SECTION 3.0

CONSERVATION PLANNING PROCESS/DESCRIPTION AND
AREA PLAN CRITERIA OF THE MSHCP CONSERVATION AREA

3.1 CONSERVATION PLANNING PROCESS

3.1.1 Process Background

The conservation planning process for the MSHCP Plan involved a variety of concurrent and sequential elements. These elements are listed below and summarized in this section.

  • Identification of overall MSHCP goals in the context of prior conservation planning efforts, stakeholder objectives and regulatory requirements;
  • Compilation of existing data and development of analysis tools;
  • Identification of applicable conservation biology principles;
  • Review of reserve selection models and methods;
  • Development of initial Conceptual Conservation Scenario;
  • Informal gap analysis;
  • Identification of alternatives and selection of proposed alternative;
  • Development and refinement of Conceptual Reserve Design/Criteria Based Plan;
  • Description and analysis of selected alternative.

3.1.2 Overall MSHCP Goals and Conservation Planning

Context

Sections 1.2.3 and 1.2.4 of this document summarize the overall planning and regulatory context within which the MSHCP conservation planning process proceeded. The range of stakeholder objectives to be addressed by the conservation planning process is presented in the planning context presented in Section 1.2.3. These various inputs resulted in the overall MSHCP goals and objectives presented in Section 1.3 of this document and in the policy direction provided by the County Board of Supervisors as noted in Section 1.3.

3.1.3 Compilation of Existing Data

A description of the biological and physical databases is provided in Section 2.1.1 of this document. In addition to these databases, a variety of other data were assembled as part of the overall RCIP process and informed the conservation planning process for the MSHCP. These include digital data layers depicting existing land use, planned land use, status of land ownership, existing and planned roads, utility easements and assessors parcels.

The biological and physical databases described in Section 2.1.1 were augmented by additional literature reviews and data gathered from a variety of sources. Input also was sought from local biologists. Representatives from the USFWS, UCR, DUDEK, RBF, Los Angeles County Museum, Coachella Valley Association of Governments, Tierra Madre Consultants (now AMEC), Camp Pendleton Amphibians and Reptiles Survey (CPARS), Zoological Society of San Diego, Loma Linda University, County of Riverside, and independent consultants convened for a three-day habitat assessment workshop on April 27 through 29, 1999. The workshop was followed by a subsequent meeting with Dr. Robert Fisher of San Diego State University and DUDEK regarding species occurrences and general conservation issues on June 9, 1999. The purpose of the habitat assessment workshops was several fold: to identify the goals and objectives of the MSHCP; to provide a forum for review of the data available for the planning effort; to discuss the status of the species data and accounts; and to discuss approaches to habitat assessment. A detailed description of the workshops can be found in Appendix C of the August 9, 1999 "Draft MSHCP Proposal" (DUDEK 1999) on file with the County of Riverside.

On June 30, 1999, a workshop hosted by UCR was conducted to further solicit information regarding species proposed for analysis as part of the MSHCP. Local biologists and other experts familiar with Western Riverside County flora and fauna discussed existing data and data gaps for the species to be addressed as well as other taxa (e.g., insects). A general evaluation of the existing data was made for each of the taxon, data gaps were identified, "hot spots" for species occurrence were noted, and corridors and areas of concern were identified. Habitat management also was discussed.

Other sources contributing to the compilation of existing data included ongoing personal communication with local biologists and biologists with the USFWS and CDFG, querying the CNDDB, and reviewing Environmental Impact Reports (EIRs) and Biological Technical Reports prepared for specific development projects within the Plan Area. This effort has been ongoing throughout the MSHCP planning process.

Analysis tools developed specifically for the MSHCP included the Bioregions map described in Section 2.1.2 of this document. An additional analysis tool to evaluate edge-affected areas under existing conditions and associated with potential conservation scenarios was developed. Edge- affected lands under existing conditions were identified using the MSHCP vegetation map, Bioregions map and major highways map. These polygon-based data layers were converted to 100-foot pixel grids. Lands were either classified as Habitat or urban/agricultural. Based on distance between urban/agricultural lands and Habitat, "Edge Effects" were defined as follows: 0-250 feet - strongly affected; 251-600 feet - somewhat affected; >600 feet - relatively unaffected. The application of this tool to analysis of the MSHCP Conservation Area is described in greater detail in Section A of the MSHCP Reference Document - Volume II of the MSHCP Plan.

3.1.4 Applicable Conservation Biology Principles

General principles of conservation biology are captured by the reserve design tenets described in the NCCP General Process Guidelines and NCCP Act (CDFG 1998). These reserve design tenets provided a framework for the conservation planning process. They can be summarized as follows:

  • conserve focus species and their Habitats throughout the Plan Area
  • conserve large habitat blocks
  • conserve habitat diversity
  • keep reserves contiguous and connected
  • protect reserves from encroachment and invasion by non-native species

The theoretical and empirical underpinnings of the NCCP reserve design tenets can be found in the conservation biology literature, of which key concepts are summarized here.

Although many factors can be incorporated into reserve design and selection, diversity, rarity, naturalness, size and representativeness are the most widely used (Margules et al. 1988). Other considerations include island biogeography design principles of MacArthur and Wilson (1963 and 1967): (1) area effect - the larger the preserve, the greater the species richness (i.e., species/area relationship) and the greater the chances of long-term viability of populations (more individuals); (2) isolation or distance effect - the less the distance between reserve units, the greater the opportunity for gene flow, colonization, and rescue effect (e.g., also see Brown and Kodric-Brown 1977); (3) species equilibrium - the number of species that an area can support is determined by a balance between colonization and extinction; and (4) Edge Effect - the larger the ratio of reserve area to reserve perimeter, the lesser the Edge Effect.

An Edge Effect is defined as a change in the "conditions or species composition within an otherwise uniform habitat as one approaches a boundary with a different habitat (Ricklefs 1993)." Edge Effects at the boundary between natural lands and human-occupied lands ("urban edge effects") arise due to human-related intrusions such as lighting, noise, invasive species, exotic predators (dogs, cats, and opossums), hunting, trapping, off-road activities, dumping, and other forms of recreation and disturbance. Although some species are in some ways unaffected by edges [e.g., reproductive output of the rufous-crowned sparrow (Morrison and Bolger 2002), distribution of arthropod species (Bolger et al. 2000)] or even show preferences for edges (e.g., indigo buntings and northern cardinals in Woodward et al. 2001), human-induced edge effects are generally unfavorable to native species.

Another important feature of reserve design is the spatial arrangement of wildlife movement corridors and Linkages between Core Areas. At this point it is useful to contrast movement corridors with Linkages. Movement corridors are often linear and facilitate efficient movement by providing adequate cover and lack of physical obstacles for movement (Beier and Loe 1992). Movement corridors do not provide Live-In Habitat for species. Linkages, in contrast, are areas providing permanent resident "Live-In" Habitat as well as movement Habitat for a particular species. The Linkage contains resources that meet the life history requirements for the species the Linkage is intended to serve. Known as landscape Linkages, these areas are capable of sustaining a full range of community/ecosystem processes, thus enabling seed dispersal and animal movement over a period of generations (USFWS 1999). Each habitat connection may be defined as a corridor or a Linkage for each species. Therefore, although areas in the MSHCP designated as Linkages may in fact function only as movement corridors for some species, for simplicity, connections between blocks of Habitat are always referred to generally as Linkages in this document.

Connectedness through landscape Linkages and movement corridors is important because habitat fragmentation and isolation lead to extinction of local populations and are the most serious threats to biological diversity. Bolger et al. (1997) found fewer rodent species in fragments isolated for longer periods of time and by greater distances. Lower arthropod diversity was also observed by Bolger et al. (2000) in older and smaller habitat fragments. The probability of extinction becomes greater as immigration and emigration are impeded by conversion of natural Habitat between occupied or potential habitat patches to inhospi land covers. Linkages, therefore, serve to ameliorate habitat fragmentation and isolation by permitting the following: (1) the travel, migration and meeting of mates for wide-ranging animals; (2) plant propagation; (3) interchange of genetic material; (4) movement of populations in response to environmental changes and disasters; and (5) colonization of available Habitat by individuals (Beier and Loe 1992).

Empirical evidence exists to support the utility of Linkages and corridors. In a study by Beier (1995), radio-tagged mountain lions never crossed into urban areas; individuals used defined movement corridors for dispersal and for traveling between areas comprising their home ranges. Beier and Noss's (1998) review of thirty-two empirical studies pertaining to the utility of wildlife corridors supported the idea that corridors are "valuable conservation tools." Price et al. (1994) also encourage the consideration of connectedness, particularly for endangered species such as the Stephens' kangaroo rat. Habitat connections are particularly important to the persistence of metapopulations which comprise this species' populations.

Using the available data, the five tenets listed at the beginning of this section were incorporated in the conservation planning process. The species list developed early in the planning process, as described in Section 2.1.4 of this document, along with the species occurrence database and input provided by local biologists and the information assembled for the species accounts (presented in Section B of the MSHCP Reference Document - Volume II of the MSHCP Plan), provided guidance for the overall species needs that would need to be met within the conserved areas. The MSHCP vegetation map, coastal sage scrub quality model, and edge analysis were combined and used in a variety of ways to identify the presence and locations of existing large habitat blocks for potential inclusion within conserved areas. These data and analyses also were used to evaluate existing and potential locations for Linkages. Data were generally analyzed by plotting hard copy maps of data layers and using acetate overlays to assess combined layers. This overlay technique was also conducted digitally using ArcView.

3.1.5 Review of Reserve Selection Models and Methods

In the spring of 1999 DUDEK reviewed several documents and papers from the "gray" and published scientific literature regarding theoretical and applied reserve selection techniques, ranging from relatively subjective ranking approaches (e.g., Duever and Noss 1990; San Diego Multiple Species Conservation Program [MSCP] and North San Diego County Multiple Habitat Conservation Program [MHCP]) to highly automated reserve selection approaches (e.g., Church et al. 1996). Based on this selective review of the literature, it was determined that these reserve selection procedures held little promise for a priori reserve design in the MSHCP planning effort for several reasons: (1) the lack of necessary data to run most of the models; (2) the lack of time and resources to collect such data; (3) the lack of time and resources to validate the results of the models; and (4) the scale differences for the MSHCP Plan Area (highly parcelized) compared to typical scales of 1/4 sections (160 acres) and sections (640 acres) used in the scientific models. Nonetheless, it is instructive to review some of the reserve selection approaches described in the literature because they illustrate many of the important concepts of conservation biology theory and provide some useful analytic approaches for evaluating the MSHCP.

There are many examples of reserve selection procedures in the literature, ranging from quantitative rankings of alternative reserve areas (Duever and Noss 1990) to automated computer algorithms that select reserve units based on pre-programmed criteria (e.g., Austin and Margules 1986; Bedward et al. 1992; Church et al. 1996; Kirkpatrick 1983; Lomolino 1994; Margules et al. 1988; Margules and Usher 1981; Rossi and Kuitunen 1996; Sætersdal and Birks 1993). The computer algorithms typically are designed to select the most efficient reserve system based on some preselected conservation currency such as the maximum number of species, rarity, or biodiversity hotspots; i.e., what reserve design provides the greatest conservation value with the least number of reserve sites? These reserve selection algorithms typically are optimizing solutions such as the Maximal Covering Location Problem (MLCP) (Church et al. 1996) or more simple heuristic iterative algorithms that find reasonable approximations to optimum solutions (e.g.,Margules et al. 1988).

A common feature of the reserve selection approaches is to establish conservation criteria, currency, or surrogates for conservation value. For example, Margules and Usher (1981) identified 18 classes of criteria for evaluating conservation value that could be incorporated into the selection procedure. Some common, but not necessarily mutually exclusive, criteria in these reserve selection models include the following:

  • biological diversity (defined in various ways)
  • size of reserve unit
  • species richness or population abundance
  • representativeness (biological and/or environmental)
  • complementarity
  • irreplaceability
  • number of endangered or threatened species
  • rarity of species
  • naturalness
  • threats
  • costs
  • management requirements

Among these criteria, diversity, rarity, naturalness, size and representativeness are most widely used (Margules et al. 1988). Although these criteria tend to be common to selection approaches, how they are defined and used varies among the different model approaches (e.g., Belbin 1993).

As described above, a basic goal of the reserve selection models is to select a set of reserve units that optimizes or maximizes the representation of the identified conservation currency with the least number of units (e.g., Camm et al. 1996; Church et al. 1996). Criteria can be systematically and interactively manipulated to compare results using different priorities, assumptions, weightings of criteria, etc. A strength of such modeling is flexibility and the ability to evaluate different approaches fairly quickly, depending on the computer resources available, number of variables in the selection model, and the size of the data set. The disadvantage of this flexibility is that there are almost infinite ways that models can be programmed with regard to criteria, assumptions, and weightings. Thus, with a large and diverse group of stakeholders, achieving consensus on the most appropriate approach is extremely difficult. Also, demonstrating the sensitivity, reliability, and external validity of any given approach would be difficult in the planning time frame. The validity of the approach can only be evaluated in terms of the viability of the reserve system. Ultimately a functional analysis of the reserve system will occur over the next several decades through the monitoring and Adaptive Management Program.

An illustration of a reserve selection application is a study by Church et al. (1996) where reserve selection is approached as a Maximal Covering Location Problem (MCLP). The MCLP finds the optimum reserve design that solves the problem of selecting "the smallest number of sites from some biological domain which represents all, or as many as possible, of the species in that domain." Using the MCLP has a number of practical problems. A key assumption of the MCLP is that the reserve selected is large enough to support a viable population of a species, community, or Habitat, thus begging the question of what constitutes a viable species, community, or Habitat. This problem would have to be resolved before the reserve selection model could be applied because the viability threshold is part of the computer algorithm. Furthermore, the exercise of evaluating species viability is itself a spatial problem (e.g., how is a viable metapopulation spatially structured), and not just specifying a certain number of populations without regard to their spatial context. Hence, application of the MCLP after this is done seems somewhat redundant, although this qualitative analysis does not address the optimality of design. Finally, it should be noted that Church et al. caution that some optimality problems may be difficult or unsolvable. As the number of variables and data set increases, it is less likely that an optimum solution exists or that it can be easily solved.

Given the uncertain application of reserve selection techniques and the broad range of additional issues that would be triggered from such approaches, DUDEK tends to agree with the assertion of Prendergast et al. (1999) that funds should be allocated for more pragmatic and policy-driven approaches to Conservation (i.e., what are the jurisdictions actually capable of doing) rather than theoretical optimization of reserve design. Regardless of the reserve design selected, and whether it is algorithm-based or stakeholder-driven, the soundness of the MSHCP Conservation Area has to be evaluated by the Wildlife Agencies and other stakeholders.

Although specific reserve selection models were not developed and used for the reasons noted above, the concepts incorporated in the models and listed above (e.g., diversity, size, representativeness, etc.) were considered in the conservation planning process. Values and goals for the conservation planning effort were identified as described in Section 3.1.2 of this document. A comprehensive database was assembled as described in Section 3.1.3 and conservation biology principles were considered as described in Section 3.1.4. Based on this framework, an initial conservation scenario was developed for review by stakeholders with initial identification of potential acreage requirements. Development of this information was necessary for stakeholders to make decisions regarding the next steps in the conservation planning process. Subsequently, as described in Section 3.1.7, alternative conservation scenarios were developed for review by stakeholders and a recommended conservation scenario was selected. The recommended conservation scenario was then refined and analyzed as described in Sections 3.1.8 and 3.2 of this document.

3.1.6 Conceptual Conservation Scenario

An initial reserve concept was developed to assist the MSHCP Advisory Committee in decisions to proceed with conservation planning efforts. This generalized Conceptual Conservation Scenario was developed based on the existing data and literature, habitat assessment workshops, species occurrence information, coastal sage scrub habitat quality modeling, existing and planned land uses, and general conservation biology principles summarized in the NCCP reserve design tenets. At the direction of the MSHCP Advisory Committee, the Conceptual Conservation Scenario was presented and described in narrative form. A map was not prepared. Also at the direction of the MSHCP Advisory Committee, the Conceptual Conservation Scenario was intended to address the life history requirements of as many species as possible on the species list developed by the MSHCP Advisory Committee ( 2-2).

A key objective of the Conceptual Conservation Scenario was to develop a rough estimate of the number of acres needed to conserve the species on the species list developed by the Wildlife Agencies in concert with the MSHCP Advisory Committee (Table 2-2). To the extent possible, existing reserves and areas with multiple species and habitat resources (i.e., ‟hot spots") were incorporated to design an efficient reserve. Core Areas were identified including areas in both existing Public/Quasi-Public Lands and new areas.

Potential Linkages connecting the Core Areas also were identified. Consideration of the species anticipated to utilize the Linkages helped determine if the Linkage should be designed as a landscape Linkage containing biological features and resources for permanent residence, as a movement corridor primarily intended to convey larger wildlife or both. The San Jacinto River is an example of a landscape Linkage that is a Core Area for Narrow Endemic Plant Species but also serves as a movement corridor across the central portion of the Plan Area for species such as the bobcat. These Narrow Endemic Plant Species are dependent on the river's hydrological processes to maintain the appropriate soil and habitat features and a mechanism for dispersal. An example of a landscape Linkage constrained by existing land use patterns is the upland connection between Core Areas in the Lake Skinner/Diamond Valley Lake area and the Estelle Mountains/Lake Mathews Reserve area. Patches of coastal sage scrub exist in this area that provide Habitat for the coastal California gnatcatcher; however, existing conditions do not provide a continuous landscape connection suitable for less mobile species such as small mammals and reptiles. Examples of movement corridors unlikely to provide Live-In Habitat for most species include undercrossings of I-15 at Indian Canyon and Horsethief Canyon for bobcats and mountain lions moving between the Cleveland National Forest and the Estelle Mountains/Lake Mathews Reserve area.

Estimating rough acreages for Conservation was an important component of the Conceptual Conservation Scenario. This process involved:

Step 1: The narrative Conceptual Conservation Scenario was roughly mapped in the form of potential conservation analysis units. This rough map was intersected with the MSHCP vegetation map and vegetation acreages within each category were calculated using GIS.

Step 2: Consistent with the approach described in the August 9, 1999 "Draft MSHCP Proposal," 100 percent of the areas characterized as developed on the vegetation map and 75 percent of the areas characterized as Agriculture on the vegetation map were deleted from the acreage totals.

Step 3: Areas developed since the MSHCP vegetation map was prepared (1995) were defined using the Existing Land Use coverage developed in 1999 for the RCIP. The Existing Land Use coverage is based on 1998 aerial photography and 1997 SCAG database. Acreage estimates were determined for areas that appear to have been developed since the MSHCP vegetation map was prepared and these acreages were deleted from the overall acreage totals.

Step 4: A global 10 percent reduction in total acreage was then assumed based on anticipated new information such as updated information regarding existing Development, updated information regarding Public/Quasi-Public Lands, updated information regarding development approvals and Covered Activities.

A rough acreage estimate was derived from the four-step process described above and then an acreage range was applied under the assumption of various levels of species Conservation. The range of conservation acreages in the Conceptual Conservation Scenario totaled 380,000 to 510,000 acres of private and Public/Quasi-Public Lands.

3.1.7 Informal Gap Analysis

Methods

Based on the Conceptual Conservation Scenario described above, an informal gap analysis was conducted. This informal gap analysis is not to be confused with the formal Gap Analysis Program (GAP) described by Scott et al. (1993), but is based on the same principles (note use of lower case for "gap analysis"). The gap analysis identified areas as important for Conservation in the Conceptual Conservation Scenario but not currently in public ownership, i.e., there is a lack ("gap") of protection in these areas. The locations of existing designated open space lands and other public lands were mapped using GIS. The initial analysis was based on the status of land ownership map (Figure 2-9). Subsequently, a preliminary parcel-based Public/Quasi-Public Lands database was developed by County staff and was used for analysis. This database was then compared with a schematic map of the Conceptual Conservation Scenario using GIS to identify the gaps in Conservation and where land may need to be acquired to assemble the MSHCP Conservation Area.

Results

The gap analysis identified 153,000 acres needed for Conservation that are not currently in public ownership (i.e., the area within the generalized Conceptual Conservation Scenario that currently is unprotected). The gaps in protection include portions of core resource areas, landscape Linkages, movement corridors or Constrained Linkages, and other important localized resource areas such as vernal pool and the Delhi Sands flower-loving fly Habitats.

A narrative summary of the gaps in protection resulting from the analysis is provided below:

3.1.8 Identification of Alternatives and Selection of Proposed Alternative

As directed by the MSHCP Advisory Committee, the initial conservation planning process focused on identifying acreage requirements for a conservation scenario that would conserve the majority of species from the initial species list (Table 2-2). The MSHCP Advisory Committee also requested identification of alternative conservation scenarios that could result in Conservation of fewer species. These alternative conservation scenarios were identified as the Listed and Proposed Species Alternative, the Listed, Proposed and Strong Candidate Species Alternative, and the Existing Reserves Alternative. These alternatives were developed and analyzed both quantitatively and qualitatively using the MSHCP database in the same manner as the Conceptual Conservation Scenario. Schematic maps were developed for GIS analysis and visual display purposes for stakeholders. The alternatives are summarized in Section 3.4 of this document and in the MSHCP Alternatives Development Document (DUDEK, October 2000). Also considered as part of this process were a No Project/No MSHCP Alternative and a "more biologically robust" alternative. The No Project/No MSHCP Alternative is summarized in Section 3.4 and in the Alternatives Development Document and the "modified reserve design" alternative is discussed in detail in the MSHCP EIR/EIS and briefly in Section 9.0 of this document.

In general, it was concluded that alternatives that resulted in Conservation of fewer species would not substantially reduce acreage requirements for Conservation, or costs associated with Reserve Assembly. It was also concluded that the "modified reserve design" alternative would result in substantially increased costs while not resulting in Conservation of additional species. Based on these general conclusions, and other factors considered by stakeholders and the County Board of Supervisors, the refinement of the initial Conceptual Conservation Scenario, known as Alternative 1, was selected as the preferred alternative and the conservation planning process proceeded with further development and refinement of that alternative.

3.1.9 Conceptual Reserve Design/Criteria-Based Plan

At the December 19, 2000 meeting of the County Board of Supervisors, policy direction was given to proceed with preparation of a criteria-based plan for Alternative 1, which would conserve approximately 500,000 acres in the Plan Area. The criteria-based approach anticipates Conservation within the existing Public/Quasi-Public Lands comprising approximately 347,000 acres and development of Criteria to describe additional Conservation on private lands of approximately 153,000 acres.

Development of the criteria-based plan involved review and refinement of the initial Conceptual Conservation Scenario and conceptual Alternative 1 and creation of the Conceptual Reserve Design. This included an iterative process of going back through the data compilation and review, gap analysis, and consideration of conservation biology principles that were completed for the Conceptual Conservation Scenario and Alternative 1. The data layers described in Sections 2.1.1 and 2.2.2 were used for this process with updated data layers reflecting new information assembled throughout the planning process. The primary information updated throughout the process were the species occurrence data and other species-specific information obtained through review of literature and comments received on draft species accounts distributed at several intervals during the process. In addition, as noted previously, the Public/Quasi-Public data base was refined. A parcel-based Public/Quasi-Public Lands database was used for the description and analysis of the proposed MSHCP Conservation Area in this document. Updated land use data also were incorporated in the process including updated identification of lands with priorconservation agreements. Updated aerial photography became available in summer 2001.

As with the process for the Conceptual Conservation Scenario and Alternative 1, a specific quantitative model was not developed for the Conceptual Reserve Design. The iterative process involved overlaying data layers manually using hard-copy plots and acetates, as well as on-screen data overlays using GIS. Initial refined concepts were developed for review and comment by the Wildlife Agencies and their comments were addressed in the refined concepts. A more detailed description of the organizing framework and methodology used to develop the Conceptual Reserve Design/Criteria-Based Plan is presented in Section 3.3.1 of this document.

3.1.10 Description and Analysis of MSHCP Conservation Area

The process described in Sections 3.1.1 through 3.1.8 resulted in identification of an MSHCP Conservation Area that could be described and analyzed. The description and analysis of the MSHCP Conservation Area have two primary purposes: (1) to provide a complete enough description of the Conservation anticipated under the MSHCP such that Reserve Assembly can be adequately measured and monitored over the long-term MSHCP implementation process, while at the same time incorporating sufficient flexibility to allow appropriate response to new information and changing conditions; and (2) to provide a sufficient level of detail to permit analysis of Covered Species consistent with regulatory requirements. A generalized description and analysis of the MSHCP Conservation Area is presented in Section 3.2 of this document and in Section A of the Reference Document - Volume II of the MSHCP Plan. The detailed species accounts are included in Section B of the Reference Document - Volume II of the MSHCP Plan and summary species accounts are provided in Section 9.0 of this document.

3.2 DESCRIPTION OF THE MSHCP CONSERVATION AREA

3.2.1 The MSHCP Plan Map

Figure 3-1 depicts the Criteria Area within the Plan Area and represents the MSHCP Plan map. Four categories are depicted on the legend for the Plan map and are described below.

Criteria Area: This represents the area within which MSHCP Criteria will be applied and from which 153,000 acres of new Conservation will be achieved to contribute toward assembly of the overall MSHCP Conservation Area. Criteria have been developed for individual Cells or Cell Groupings and are presented for each Area Plan in Section 3.3.

Public/Quasi- Under this category, existing known Public/Quasi-Public Lands (PQP)

Public Lands: that will form the initial backbone of the MSHCP Conservation Area are depicted. Approximately 347,000 acres of Conservation are anticipated on these lands.

Within five years of Permit issuance, the RCA shall verify the precise acreage, location, amount and status of PQP Lands in the MSHCP Conservation Area. Such information shall be submitted to the Wildlife Agencies for review. In the event that a Permittee elects to use property currently depicted as PQP Lands on the MSHCP Plan map (Figure 3-1) in a way that alters the land use such that it would not contribute to Reserve Assembly the Permittee shall locate and acquire or otherwise encumber replacement acreage at a minimum ratio of 1:1 replacement taking into account direct and indirect effects of PQP Lands in one location with PQP Lands in another location. The Permittee must make findings that the replacement acreage is biologically equivalent or superior to the existing property as set forth in Section 6.5 of the MSHCP, Volume I.

 

 

 

 

 

 

Rural Mountainous Designation: This category represents the Rural/Mountainous land use designation incorporated in the County General Plan. In general these lands are characterized by steep slopes that represent constraints to Development. For example, of the approximately 54,900 acres depicted on the MSCHP Plan map outside the Criteria Area but within the Rural Mountainous designation, approximately 42,500 acres (77 percent) are characterized by slopes with gradients greater than 30 percent. While Reserve Assembly activities are not expected to occur in Rural Mountainous designation areas outside the Criteria Area, existing and future land use practices in these areas may provide an edge for the MSHCP Conservation Area that would minimize Edge Effects when compared with more urban land uses.

 

 

American Indian Lands: American Indian Lands are depicted on the MSHCP Plan map for reference purposes. No Conservation is assumed on these lands and no activities on these lands would be permitted under the MSHCP. The American Indian Lands are not a part of the MSHCP.

The MSHCP Conservation Area will be comprised of existing Public/Quasi-Public Lands and new Conservation on approximately 153,000 acres of land within the Criteria Area. While the precise configuration for new Conservation within the Criteria Area has not been defined or mapped, a Conceptual Reserve Design was developed for analysis purposes as described in Sections 3.1.9 and 3.3.1 of this document. While certainly not the only possible configuration to emerge from application of Criteria within the Criteria Area, the Conceptual Reserve Design was a useful tool in establishing conservation targets as part of the MSHCP planning process. The conservation targets developed as part of that process, along with anticipated Conservation on Public/Quasi-Public Lands, form the basis for the description of the MSHCP Conservation Area presented in this section. Achievement of the conservation targets as part of the overall Reserve Assembly process will be an important measuring and monitoring tool for the MSHCP.

3.2.2 The MSHCP Conservation Area

In addition to the features incorporated in the MSHCP Plan map, as described above, the MSHCP Conservation Area may be described in terms of several specific analysis factors considered during the conservation planning process. These include Bioregions, vegetation, soils, patch size, and edge affected lands. This section provides a summary description of the MSHCP Conservation Area based on those analysis factors. A more detailed description is provided in Section A of the MSHCP Reference Document - Volume II of the MSHCP Plan. The MSHCP Conservation Area may also be described in terms of Cores and Linkages. The description of Cores and Linkages is provided in Section 3.2.3 of this document.

Bioregions

Within the MSHCP Plan Area, large percentages of the Agua Tibia mountains (80.3 percent, 10,130 ac.), San Jacinto Mountains (71.7 percent, 134,000 ac.), San Jacinto Foothills (64.6 percent, 72,240 ac.) and the Santa Ana Mountains (61.3 percent, 85,810 ac.) Bioregions are conserved. Significant amounts of the Conservation in these Bioregions occur within existing Public/Quasi-Public Lands. Smaller portions of the Desert Transition (37.7 percent, 33,460 ac.), San Bernardino Mountains (34.5 percent, 9,990 ac.) and Riverside Lowlands (24.2 percent, 166,820 ac.) are conserved within the MSHCP Plan Area. Much of the central portion of the Desert Transition Bioregion will not be conserved. Six percent of the Desert Transition Bioregion currently supports urban Development or agricultural uses. About ten percent of the San Bernardino Mountains Bioregion currently has urban or agricultural land uses. The remaining non-conserved lands are either American Indian Lands (5.7 percent), Rural Mountainous (15.7 percent), or undeveloped private land. The Riverside Lowlands is the largest Bioregion and will have the lowest proportion of its acreage in Conservation, with 24.2 percent (166,820 acres) within the MSHCP Conservation Area. Approximately 50.4 percent (about 347,800 acres) of the land in this Bioregion is currently supporting urban or agricultural land uses. Very little of this Bioregion is within American Indian Lands or is considered Rural Mountainous.

Vegetation

Table 3-1 presents a summary of Vegetation Communities conserved within the MSHCP Conservation Area. Playas/vernal pools and water vegetation types had the highest percentages of Conservation within the MSHCP Conservation Area, with 85 percent of the total acreages of both these Vegetation Communities conserved. Riparian scrub/woodland forest, Riversidean alluvial fan sage scrub, woodlands/forests, chaparral, montane coniferous forest, coastal sage scrub and meadows/marshes also are conserved at high levels, with 50 percent to 75 percent of each of these Vegetation Communities conserved. Desert scrubs, grassland, Agriculture, and cismontane alkali marsh are conserved at the lowest levels, with percentages of Conservation at 34 percent, 28 percent, 12 percent, and 3 percent, respectively.

Total is not exact due to rounding.

Soils

Clay soils within the Plan Area include Bosanko, Auld, Altamont, and Porterville. In addition, areas from which clay had been mined (known as "claypit") were digitized. Within the Plan Area, clay soils support several sensitive plant species, including listed species such as Munz's onion (state threatened, federally endangered), thread-leaved brodiaea (state endangered, federally threatened), and San Diego button celery (state and federally endangered); and sensitive species such as Orcutt's brodiaea, long-spined spine flower, small-flowered morning glory, many-stemmed dudleya, Palmer's grapplinghook, graceful tarplant, and small-flowered microseris. The Domino-Traver-Willows soil association includes saline-alkali soils largely located along floodplain areas within the Plan Area. Sensitive plants supported by the Domino-Traver-Willows soil association include two listed species, the San Jacinto Valley crownscale (federally endangered) and the spreading navarretia (federally threatened); and sensitive plant species, including Parish's brittlescale, Davidson's saltscale, Coulter's goldfields, and vernal barley.

Within the clay soils areas, 31 percent of the total is conserved, including 12 percent within Additional Reserve Lands and 19 percent on existing Public/Quasi-Public Lands. Of these clay soils, 18 percent of Auld, 23 percent of Bosanko, 37 percent of Porterville, 10 percent of claypit, and 12 percent of Altamont are conserved either on Public/Quasi-Public Lands or captured within the Additional Reserve Lands. Within Domimo-Traver-Willows soils, 36 percent of the total is conserved, including 21 percent within the MSHCP Conservation Area and 15 percent on existing public lands. Within this soil association, 17 percent of Domino, 32 percent of Traver, and 74 percent of Willows soils are conserved either on Public/Quasi-Public Lands or within Additional Reserve Lands.

Patch Size

The individual sizes of patches comprising the MSHCP Conservation Area are important elements to the functioning of the conserved lands. It is generally agreed that large-sized patches encompass a greater portion of the landscape and allow for a greater inclusion of ecological niches, and that larger Core Areas offer greater resistance to catastrophic changes. However, while larger-sized Core Areas are usually considered better-functioning, widespread smaller satellite Core Areas can incorporate higher species diversity by efficiently preserving nodes of species of limited distribution. The MSHCP Conservation Area has both small and large areas in order to balance the need to conserve narrowly-distributed species and preserve the greatest number of species and protect habitat function with the least management effort.

The MSHCP Conservation Area is composed of approximately 575 patches. The spatial character of the MSHCP Conservation Area is complex with large numbers of small, spatially disjunct patches and small numbers of large connected patches. Sixty-five percent of these patches are less than ten acres in area and make up less than 0.25 percent of the areas to be conserved under the MSHCP. The vast majority of these small patches occur within areas heavily fragmented by urbanization in the Riverside Lowlands Bioregion and are represented by small patches of existing Public/Quasi-Public Lands. By contrast only 28 of the patches (5 percent) are greater than 1,000 acres but these make up 94 percent of the areas to be conserved under the MSHCP. A single connected block makes up the largest portion of the MSHCP Conservation Area at approximately 238,000 acres (50 percent of the acreage).

Edge Affected Land After Completion of Reserve Assembly

Increases in fragmentation of the landscape lead to increases in the area where urban/agricultural landscapes and native habitats interface. These areas of high fragmentation are subjected to Edge Effects, which are generally unfavorable and are ultimately due to nearby human activity. Some examples of Edge Effects include introduction/colonization of non-native species, increased predation, increased fire frequency, and small-scale environmental changes in temperature, light, and wind (Primack, 1993).

The MSHCP Conservation Area will be subjected to these Edge Effects due to urbanization within the Plan Area. For the purposes of estimating Edge Effects on habitat patches at completion of Reserve Assembly, each acre within the MSHCP Conservation Area (excluding urban and agricultural land) was placed into one of three categories based on proximity to urban/agricultural lands: strongly affected (1 to 250 feet from urban or agricultural land), somewhat affected (251 to 600 feet from urban or agricultural land), and not affected (more than 600 feet from urban or agricultural land).

From this analysis, it was found that 14 percent of the MSHCP Conservation Area will be strongly affected, 15 percent will be somewhat affected, and 71 percent will not be affected by Edge Effects. This large percentage of lands not likely to be exposed to Edge Effects is due to the effect of a small number of large habitat blocks. The strongly urban/agricultural areas of the Riverside Lowlands Bioregion and San Bernardino Mountains Bioregion have the greatest proportion of land that may be subject to Edge Effects.

3.2.3 Cores and Linkages within the MSHCP Conservation Area

The MSHCP Conservation Area is comprised of a variety of existing and proposed Cores, Extensions of Existing Cores, Linkages, Constrained Linkages and Non-contiguous Habitat Blocks. These features, generally referenced as Cores and Linkages, are depicted in Figure 3-2. The following definitions apply to the legend items shown on Figure 3-2.

Core A block of Habitat of appropriate size, configuration, and vegetation characteristics to generally support the life history requirements of one or more Covered Species. Although a more typical definition is population-related and refers to a single species (see Hunter 2002, Primack 2000), in the MSHCP this term is Habitat-related because of the multi-species nature of the MSHCP Plan.

Extension of Existing Core A block of Habitat contiguous with an existing Core Area which serves to provide additional Habitat for species in the adjacent existing Core and to reduce exposed edge.

Non-contiguous Habitat Block A block of Habitat not connected to other Habitat areas via a Linkage or Constrained Linkage.

Constrained Linkage A constricted connection expected to provide for movement of identified Planning Species between Core Areas, where options for assembly of the connection are limited due to existing patterns of use.

Linkage A connection between Core Areas with adequate size, configuration and vegetation characteristics to generally provide for "Live-In" Habitat and/or provide for genetic flow for identified Planning Species. Areas identified as Linkages in MSHCP may provide movement Habitat but not Live-In Habitat for some species, thereby functioning more as movement corridors. Since it is expected that every Linkage will provide Live-In Habitat for at least one species, and since the term "corridor" may be easily confused with the term as it is applied to transportation Corridors discussed in the CETAP portion of the RCIP, the term Linkage is used here. For a more thorough discussion of Linkage and movement corridors, see Section 3.1.4, Applicable Conservation Biology Principles.

 

 

 

 

 

 

The Cores and Linkages depicted in Figure 3-2 are based on the Conceptual Reserve Design developed for analytical purposes for the MSHCP. Likewise, the quantitative information presented with each Core or Linkage is based on the Conceptual Reserve Design. As described in Section 3.2.1 of this document, the Conceptual Reserve Design forms the basis for identifying target conservation acreages and generating quantitative data for the MSHCP biological analyses. The Conceptual Reserve Design is intended to describe one way in which the MSHCP Conservation Area could be configured consistent with MSHCP Criteria; it does not represent the only possible reserve that could be assembled consistent with the MSHCP Criteria. Flexibility is intended to be incorporated in the Reserve Assembly process to enable new information and data to be incorporated as part of the long-term MSHCP implementation process.

 

 

The tables in the text discussion present four categories of information for each Core or Linkage: Dimensions, Species, Adjacent Planned Land Uses, and Covered Activities.

1. Dimensional Data. Dimensional data include total acreage, edge, interior, P/A ratio, and distance to nearest Core. For Cores, Non-contiguous Habitat Blocks, and Extensions of Existing Cores, only total area, P/A ratio, and distance to the nearest connected Core are considered. For Linkages and Constrained Linkages, only total area, P/A ratio minimum/ maximum widths and lengths are considered.

Total area contained within a Core or Linkage was calculated based on the Conceptual Reserve Design and then was divided into area classified as edge and area classified as interior. To complete this edge analysis, a 250-foot buffer was created outside and adjacent to the Core or Linkage and designated "edge" area, while the remaining area was designated "interior." It is anticipated that these edge areas will incur greater "Edge Effects" due to nearby human activities such as lighting, urban runoff, toxics such as pesticides, or domestic predators. For the sake of simplicity, a 250-foot buffer was used, though in reality Edge Effects may decrease in a complex fashion, depending on species and type of Edge Effect, from the margin to the interior of the Core or Linkage (see Section 3.1.4 for a more thorough discussion of Edge Effects.). In addition, the extent to which a Core or Linkage is affected by edge varies as a function of the land use surrounding the Core or Linkage. For example, a Rural Mountainous land use designation in areas adjacent to a Linkage would give rise to far fewer Edge Effects than a city land use designation surrounding the Linkage. Land use designations surrounding each Core and Linkage are discussed in the individual Core and Linkage descriptions following the tables. Finally, Edge Effects are also species specific, since different species respond differently to Edge Effects.

The tables also present the distance to nearest connected Core and the perimeter-to-area (P/A) ratio of each Core or Linkage, as appropriate. Once a GIS coverage delineating Cores and Linkages was created, perimeters and areas were computed with GIS in order to determine the P/A ratio. Distance to nearest connected core was identified as the length of each linkage connecting the cores in question. From a biological perspective low P/A ratios are generally considered more favorable since low P/A ratios represent unfragmented habitat blocks with comparatively lower amounts of exposed edge. As the overall size of the Core or Linkage increases, however, the importance of this metric may decrease. In cases where more than one route through a Linkage is possible, the reader is referred to the text description of the Linkage.

Note: The sum of the areas for the proposed Cores and Linkages is 183,000 acres, a value above the target acreage of 153,000 acres of new Conservation on private lands. This difference arises as an artifact of the classification of each Core or Linkage as either "Proposed" (i.e., new, private Conservation) or "Existing" (i.e., Public/Quasi-Public Land) despite the fact that some Cores or Linkages contain a patchwork of Public/Quasi-Public Lands and private lands identified for potential acquisition. Thus, the additional 30,000 acres contained within the proposed Cores or Linkages reflects the inclusion of existing Public/Quasi-Public Lands within the proposed Cores and Linkages.

2. Planning Species. Planning Species considered for each Core or Linkage are also listed in the tables. Planning Species are subsets of Covered Species that are identified to provide guidance for Reserve Assembly in Cores and Linkages and/or Area Plans. Species listed in this column may include species which are not Planning Species for the area in question but which may have important or key populations located in the area.

3. Adjacent Proposed General Plan Land Use. Each table lists General Plan land uses proposed adjacent to the Core or Linkage, as defined by the County of Riverside General Plan. Proposed land uses include Agriculture, Community Development (including Community Centers), Open Space/Conservation, Cities, Rural (including Mountainous), Indian Lands, and Water. For specific descriptions of each of these categories, refer to the General Plan. Adjacent land uses are important because of the Edge Effects each exerts on each Core or Linkage. Community Development and Cities represent an urban level of Development with a high density of people and associated structures, vehicles, and activity. Agriculture and Rural (non-mountainous) represent land use designations with minimal structures and more open, vacant land. Rural Mountainous is typically an even lower-density land use due to steep slopes. Open space/Conservation lands are generally the most undeveloped, as they contain few, if any, structures and are specifically intended for the preservation of natural resources. Land use practices within these designations could affect resources within the Cores and Linkages due to issues such as those identified in Section 6.1.4 of this document. These issues include lighting, urban runoff, toxics such as pesticides, or domestic predators. MSHCP policies and procedures included in Section 6.0 of this document and in the global and species-specific objectives in Section 9.0 of this document will be implemented to ensure that the existing Habitat and movement functions of the Linkage are maintained as planned land uses are developed along the edge of the Linkage.

4. Major Covered Activities. Major Covered Activities that may affect the Cores and Linkages are also listed in the tables. These Covered Activities may include new facilities or widenings or extensions of existing facilities. Guidelines for Covered Activities presented in Section 7.0 of this document will be incorporated in the siting, design, construction and maintenance of these facilities to avoid and minimize effects of these facilities on Core and Linkage biological functions and values.

Quantitative data shown below for each Core and Linkage are based on the Conceptual Reserve Design. As noted in Section 3.3.1, the Conceptual Reserve Design was developed primarily for the purposes of developing quantitative information for the MSHCP species accounts and Area Plan Criteria. The Conceptual Reserve Design does not represent the only possible MSHCP Conservation Area that may be assembled during the long-term Reserve Assembly process. Flexibility is incorporated in the MSHCP to allow Reserve Assembly to be informed by project-specific data and planning as part of MSHCP implementation.

Index for Cores and Linkages

The Cores and Linkages are organized with their corresponding page numbers in this section as follows:

Existing Core A

Existing Core A consists of Prado Basin and the Santa Ana River, located in the northwest region of the Plan Area. This southwest-to-northeast trending swath of land is composed largely of Public/Quasi-Public Lands owned by a variety of entities, but it also contains a small number of privately-owned lands. The Core also functions as a Linkage, connecting Orange County to the west with San Bernardino County to the north. Existing Core A is connected to Existing Core B (Cleveland National Forest) via both and upland and a riparian connection (Proposed Constrained Linkage 1 and Proposed Constrained Linkage 2, respectively). This Core is constrained on all sides by existing urban development and agricultural use, and planned land uses surrounding the Core consist largely of high impact land uses such as city and community Development. Therefore, high quality riparian Habitat within the Core and along the edges must be maintained for species such as southwestern willow flycatcher, yellow warbler, yellow-breasted chat, western yellow-billed cuckoo, and others listed in the table below. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Maintenance of existing floodplain processes and water quality along the Santa Ana River is also important to Santa Ana River woollystar and arroyo chub. Management entities in this existing Core include: the County of Riverside Parks and Open Space District, U.S. Army Corps of Engineers, Orange County Water District, and California Department of Parks and Recreation.

Existing Core B

Existing Core B is composed of Cleveland National Forest, which lines the western border of the Plan Area. Within the Plan Area this Core consists of two large and two small blocks of Public/ Quasi-Public Lands. Existing Core B is connected to Existing Core A (Prado Basin/Santa Ana River) in the north via two Constrained Linkages (Proposed Constrained Linkage 1 and Proposed Constrained Linkage 2), in the center by Proposed Linkage 1 to the Lake Mathews/Estelle Mountain area, and in the south to the Tenaja Corridor (Proposed Linkage 9). This Core represents the second largest habitat block in the Plan Area and is located only 1.6 miles from the nearest connected Core. Studies of mountain lion movement within this Core indicated that this Core provides both Live-In and Linkage Habitat for this mammal, which requires very large blocks of intact Habitat. The Core then likely also provides linkage area for other mammals such as mountain lion and bobcat in addition to the species listed in the table below. Management entities in this existing Core include the U.S. Forest Service.

Existing Core C

Existing Core C consists of public lands in the Lake Mathews/Estelle Mountain area in the northwestern region of the Plan Area, originally assembled as a Core Reserve for the Stephens' Kangaroo Rat Habitat Conservation Plan. Connections to other MSHCP conserved lands exist to the east (Proposed Linkage 3) and west (Proposed Extension of Existing Core 2). This Core is somewhat constrained by existing agriculture to the north and south of the Core; however some natural lands remain along the border of the Core. A large portion of the western border of Existing Core C is contiguous with Proposed Extension of Existing Core 2, which markedly decreases amount of exposed edge and results in a lower actual P/A ratio than that reported in the table below. This Core provides Live-In Habitat for a large number of species as well as linkage area for species moving from the Gavilan Hills area to Temescal Wash. In addition to Stephens' kangaroo rat, the Lake Mathews/Estelle Mountain Reserve contains Habitat for other species with requirements for high quality Habitat, such as Quino checkerspot butterfly and coastal California gnatcatcher. Although the Core is surrounded largely by a rural planned land use designation, in areas where community Development is planned, treatment and management of edge conditions along the borders of this Core will be necessary to ensure that it provides Habitat and movement functions for species using the Core. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Management entities in this existing Core include the Lake Mathews/Estelle Mountain Reserve Management Committee.

Existing Core D

Existing Core D consists of Sycamore Canyon Park. This Core is composed of two Non-contiguous Habitat Blocks of Public/Quasi-Public Land separated by approximately 2,000 feet, in approximately the north-central region of the Plan Area. Existing Core D is connected to Existing Noncontiguous Habitat Block A (Box Springs Mountains) via Proposed Constrained Linkage 7. At 10.8 miles from the nearest connected Core, Existing Core D is the most isolated of all proposed or existing Cores. The Core is also surrounded by City and Community Development planned land use designations. For these reasons, treatment and management of edge conditions along this Core will be necessary to ensure that it provides Habitat and movement functions for species using the Core. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. The Core provides Live-In Habitat for the granite spiny lizard, a species requiring rock outcrops, and likely provides movement Habitat for bobcat. Management entities in this existing Core include the City of Riverside Park and Recreation Department and March Joint Powers Authority.

Existing Core E

Existing Core E consists of Lake Elsinore, located in the west-central region of the Plan Area. Existing Core E is connected to other MSHCP conserved lands via Proposed Extension of Existing Core 3 (Lake Elsinore Soils). This Core provides Live-In Habitat for species as noted in the table below and also likely provides for movement of common mammals such as bobcat. Urban Development partially constrains the Core; however some natural lands remain along the border of the Core. Since this is an existing Core with no new Reserve Assembly anticipated, treatment and management of edge conditions along this Core will be necessary to ensure that it provides Habitat and movement functions for species using the Core. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1.4 of this document.

Existing Core F

Existing Core F consists of the Santa Rosa Plateau Ecological Reserve, located in the southwest region of the Plan Area. Existing Core F is connected to other MSHCP conserved lands via several Linkages: Proposed Constrained Linkage 13 (Murrieta Creek) and Proposed Linkage 10 connect the Core to conserved lands in the southeast, Proposed Constrained Linkages 11 (De Luz Canyon) and 12 (Sandia Canyon) connect the Core to San Diego County in the south, and Proposed Linkage 9 (Tenaja Corridor) connects the Core to Existing Core B in the west. This Core represents a large habitat block with a relatively low proportion of its area potentially affected by edge (approximately 460 acres of the total 8,360 acres) and a comparatively low P/A ratio. Furthermore, much of the Core is surrounded by a Rural Mountainous land use designation, which will further lower Edge Effects at the borders of the Core. For these reasons Existing Core F can be expected to provide high quality movement and Live-In Habitat for the species listed in the table below. Maintenance of hydrological processes and water quality will be necessary, however, to provide Habitat for persistence of species such as vernal pool fairy shrimp, thread-leaved brodiaea, Orcutt's brodiaea, western pond turtle, vernal barley, Riverside fairy shrimp, Santa Rosa Plateau fairy shrimp, and California red-legged frog. Management entities in this existing Core include: The Nature Conservancy, County of Riverside and California Department of Parks and Recreation.

Existing Core G

Existing Core G is comprised of the Santa Margarita Ecological Reserve. This Core Area provides Live-In Habitat for species noted below and may serve as a Linkage for Planning Species, including bobcat and mountain lion, moving between the Santa Ana Mountains and the Agua Tibia Wilderness. In addition to maintenance of habitat quality, maintenance of existing floodplain processes along Santa Margarita River is important for these species. Adjacent land use practices which may affect movement of species through this Core include construction of barriers (i.e., fencing). Proposed widening activities of I-15 may also affect movement of wildlife species connecting to this Core Area, as well as water quality and floodplain processes of the Santa Margarita River. Because the distance to the Santa Rosa Plateau, the nearest connected Core Area, is 5.5 miles, maintenance of the connection to the Santa Rosa Plateau is important for species persistence, viability and dispersal. Management entities in this existing Core include: California State University, San Diego, The Nature Conservancy, and California Department of Fish and Game.

Management entities in this existing Core include the Bureau of Land Management and California Department of Parks and Recreation.

Existing Core M

Existing Core M consists of the Agua Tibia Mountains, located along the south-central border of the Plan Area. Existing Core M is connected to other MSHCP conserved lands in the north via Proposed Linkages 17 (Woodchuck Road) and 18 (Arroyo Seco Creek) and Proposed Core 7 (Wilson Valley/Aguanga). Existing Core M is not constrained by existing urban development or agricultural uses. A very low proportion (approximately 180 acres of the 10,460 total acres) of the area of the Core is affected by edge, and the P/A ratio is also comparatively very low. Thus the Core can be expected to provide high quality movement and Live-In Habitat for the species listed in the table below. Additionally, a large portion of the border of Existing Core M is contiguous with Proposed Core 7 (Wilson Valley/Aguanga), which markedly decreases actual amount of exposed edge and ostensibly lowers the P/A ratio reported in the table. Management entities in this existing Core include the U.S. Forest Service.

Proposed Extension of Existing Core 1

Proposed Extension of Existing Core 1 (Prado Basin Extension) consists of private land located along the northwestern border of the Plan Area. This extension is present as two disjunct parcels in close proximity which serve to extend Existing Core A (Prado Basin/Santa Ana River). Proposed Extension of Existing Core 1 is connected only to Existing Core A within the Plan Area. In addition to adding to the functional area of Existing Core A, the presence of Proposed Extension of Existing Core 1 lowers the potential for Edge Effects in the area. Key populations of western yellow-billed cuckoo, southwestern willow flycatcher, Cooper's hawk, downy woodpecker, American bittern, black-crowned night heron, California horned lark, least Bell's vireo, tree swallow, white-tailed kite, and yellow warbler are supported by Proposed Extension of Existing Core 1. This area is also likely to be important for mountain lion movement from the Santa Ana Mountains to the Chino Hills beyond the Plan Area and is thought to provide for local movement of common mammals such as bobcat.

Proposed Extension of Existing Core 2

Proposed Extension of Existing Core 2 (Lake Mathews/Estelle Mountain Extension) consists of private lands located in the western region of the Plan Area. This extension is contiguous with Existing Core C (Lake Mathews/Estelle Mountain) along the length of its eastern border and serves to extend the Habitat in the Lake Mathews/Estelle Mountain area and smooth out edges along the border of this Core. Proposed Extension of Existing Core 2 is also connected to Proposed Constrained Linkage 4 (North Temescal Wash) in the north; and Proposed Linkage 1 and Proposed Constrained Linkages 3, 5 (Horsethief Canyon), and 6 (Temescal Wash south) in the south. The extension provides Habitat for species as listed in the table below, and also provides for movement of species. The Lake Mathews/Estelle Mountain Extension supports populations of coastal California gnatcatcher; thus high quality, connected Habitat must be maintained in this area which is surrounded by city (Corona) and community Development planned land uses. In addition, the proposed Hemet to Corona/Lake Elsinore CETAP Corridor Alternative 1B intersects the extension and may contribute to Edge Effects, if chosen. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Extension of Existing Core 3

Proposed Extension of Existing Core 3 (Lake Elsinore Soils) consists of two blocks of land extending from the southern border of Existing Core E (Lake Elsinore). The northern portion of the proposed extension is also connected to Proposed Linkage 8. Proposed Extension of Existing Core 3 conserves soils of the Traver series, which is important to the maintenance of several species of Narrow Endemic Plants. The northern portion of the extension also provides for movement of species along the lower San Jacinto River to Proposed Linkage 8. Together with Existing Core E, Proposed Extension of Existing Core 3 provides Habitat for shorebird use. Since surrounding land uses include city (Lake Elsinore) and community Development, management of edge conditions in this area will be necessary to maintain high quality Habitat in this area. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Extension of Existing Core 4

Proposed Extension of Existing Core 4 is comprised of the middle reach of the San Jacinto River and is contiguous with Core Area in Lake Perris Recreation Area. It provides Habitat for a number of Narrow Endemic Plant Species and movement for species connecting to Lake Perris and areas downstream of the San Jacinto in Canyon Lake. Planning Species for which Habitat is provided for within this proposed Extension of Existing Core include San Jacinto Valley crownscale, thread-leaved brodiaea, arroyo toad and Los Angeles pocket mouse. Maintenance of floodplain processes along the San Jacinto River, as well as maintenance of habitat quality of vernal pool complexes and the Traver-Willow-Domino soils supporting plant species noted in the table below, are important for these species. As shown on the table below, areas not affected by edge total approximately 2,890 acres of the total 3,330 acres occupied by this Extension of Existing Core. Since this Extension of Existing Core may be affected by edge, treatment and management of edge conditions will be necessary to ensure that it provides Habitat and movement functions for species using this Core. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Flood control activities associated with the Community Development land use designation and major Covered Activities may adversely affect Planning Species known to occur within the San Jacinto River.

Proposed Extension of Existing Core 5

Proposed Extension of Existing Core 5 consists of upland Habitat adjacent to Core Areas in Lake Skinner and Johnson Ranch. This extension occurs as two disjunct parcels which serve to extend Core Areas in Johnson Ranch and Lake Skinner and reduce the amount of area exposed to Edge Effects. This Extension of Existing Core would contribute to Conservation of species occurring within Core Areas in Diamond Valley Lake, Lake Skinner, and Johnson Ranch, such as mountain lion, bobcat, coastal California gnatcatcher, Quino checkerspot butterfly and Stephens' kangaroo rat. It would also broaden the connection between Johnson Ranch and Lake Skinner. Maintenance of habitat quality and contiguity with adjacent Core Areas is important for these species.

Major Covered Activities that may affect this area include Butterfield Stage Road which would be extended north from the city limits of Temecula.

Proposed Extension of Existing Core 6

Proposed Extension of Existing Core 6 consists of upland Habitat immediately southwest of Core Areas in Lake Skinner and Johnson Ranch. This extension is contiguous with Core Area to the north in Lake Skinner and to west in Johnson Ranch. This Extension of Existing Core would contribute to Conservation of species occurring within the Core Areas in Diamond Valley Lake, Lake Skinner, and Johnson Ranch, including mountain lion, bobcat, coastal California gnatcatcher, Quino checkerspot butterfly and Stephens' kangaroo rat. It would also broaden the connection between Johnson Ranch and Lake Skinner. Maintenance of habitat quality and contiguity with adjacent Core Areas is important for these species. In addition to indirect effects of adjacent land uses described in Section 6.0 of this document, runoff and the use of toxics associated with agricultural planned land use located adjacent to MSHCP Conservation Areas may adversely affect species noted in the table below.

The proposed widening improvements to major Covered Activities, including Borel Road and Buck Road, may directly affect Habitat or result in habitat fragmentation.

Existing Constrained Linkage A

Existing Constrained Linkage A consists of lands in conservation easement in the Skunk Hollow area. This Public/Quasi-Public Linkage exists as two nearly elliptical blocks separated by approximately 330 feet in the south-central region of the Plan Area. The presence of these lands in the MSHCP decreases the gap between the Proposed Core 2 (Antelope Valley) to the west of the Linkage and the Johnson Ranch section of Existing Core J to the east of the Linkage. This Linkage is constrained by existing agriculture on all sides of the Linkage that are not connected to other MSHCP Conservation Area lands. This Linkage likely provides for movement of common mammals such as bobcat. As shown in the table below, areas not affected by edge within this Linkage total approximately 230 acres of the approximately 310 total acres of the Linkage. This represents a relatively high proportion of area not affected by edge compared to other MSHCP Constrained Linkages; therefore this area likely functions as a small block of Core Area. Nonetheless, as the planned land uses surrounding Existing Constrained Linkage A include city (Temecula) and community Development, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Existing Constrained Linkage B

Existing Constrained Linkage B is comprised of Salt Creek. This Linkage provides Habitat for species and also provides for movement of species from the Hemet area in the east, through the central region of the Plan Area, to Canyon Lake in the west. This Linkage is constrained by existing urban and agriculture along both the northern and southern edges of the Linkage. As shown in the table below, areas not affected by edge within this Linkage total approximately 5 acres of the approximately 325 total acres of the Linkage. The Linkage also possesses the second largest P/A ratio of all Linkages and Constrained Linkages and is surrounded by planned land uses designated City and Community Development, indicating that the potential for Edge Effects in this Linkage is extremely high. Therefore, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. In addition, maintenance of existing floodplain processes along Salt Creek is important for a number of the Narrow Endemic Plant Species listed in the table below. MSHCP policies and procedures included in Section 6.0 of this document will be implemented to ensure that the existing Habitat and movement functions of the Linkage are maintained as planned land uses are developed along the edge of the Linkage. Management entities in this existing Constrained Linkage include the Riverside County Flood Control and Water Conservation District.

Existing Constrained Linkage C

Existing Constrained Linkage C consists of the middle segment of the San Jacinto River, located in the northeast region of the Plan Area. This Public/Quasi-Public Linkage connects Proposed Core 5 in the east (upper San Jacinto River area) with Proposed Constrained Linkage 20 to the west. It is also connected to Proposed Core 3 (Badlands/Potrero area) via Proposed Constrained Linkage 21. Like Existing Constrained Linkage B (Salt Creek), Existing Constrained Linkage C is constrained on all sides by existing Development, has large amounts of area potentially affected by edge (approximately 240 acres of the total 245 acres), and possesses a high P/A ratio (230 feet per acre). However, unlike Salt Creek, this Constrained Linkage is largely surrounded by an open space/ conservation planned land use. Thus Edge Effects may not affect the Linkage to such a strong degree. In areas of the Linkage bordering a planned land use designated city, however, treatment and management of edge conditions along the Linkage will still be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Furthermore, maintenance of existing floodplain processes along the San Jacinto River is important for a number of the Narrow Endemic Plant Species listed in the table below.

Existing Constrained Linkage D

Existing Constrained Linkage D is comprised of Bautista Creek. This Linkage provides Habitat for species noted below, movement of species along the San Jacinto River, and a connection to Cactus Valley and the San Jacinto Mountains. This Linkage is constrained by proposed General Plan Community Development designation along both sides of this existing Linkage. Planning Species, for which Habitat is provided within this Linkage, include least Bell's vireo, southwestern willow flycatcher, arroyo toad, western pond turtle, mountain yellow-legged frog, San Bernardino kangaroo rat, and slender-horned spine flower. In addition to maintenance of habitat quality, maintenance of existing floodplain processes along Bautista Creek is important for these species. This Linkage likely provides for movement of common mammals such as bobcat. As shown on the table below, areas not affected by edge within this Linkage total approximately 10 acres of the total 120 acres of the Linkage. Since this is an existing Constrained Linkage with no new Reserve Assembly anticipated and it is already affected by edge, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Existing Constrained Linkage E

Existing Constrained Linkage E is generally comprised of lands set aside as part of a pre-existing conservation agreement and lower Tucalota Creek. This Linkage provides potential nest sites and foraging Habitat for certain species and connections to Core Areas in French Valley and Johnson Ranch. This Linkage is constrained by existing agricultural practices and roadways, including Borel Road and Pourroy Road. Planning Species for which Habitat is provided within this Linkage include grasshopper sparrow, Bell's sage sparrow, and Munz's onion. Maintenance of habitat quality and floodplain processes along lower Tucalota Creek are important for these species. This Linkage likely provides for movement of common mammals such as bobcat. As shown on the table below, areas not affected by edge within this Linkage total approximately 40 acres of the total 180 acres of the Linkage. Since this is an existing Linkage already affected by edge, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using this Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Existing Linkage A

Existing Linkage A consists of a parcel of BLM-owned (Public/Quasi-Public) land located on the southern border of the Plan Area, directly east of I-15. This Linkage is connected to other MSHCP conserved lands via Proposed Constrained Linkage 14 (Pechanga Creek). The Linkage may be used to move from Pechanga Creek south into San Diego County (a journey of approximately 7,350 feet), or to the east, to Rural Mountainous land beyond the Linkage (a journey of approximately 7,740 feet). Existing agriculture or urban Development do not constrain the Linkage, which is surrounded largely by a planned land use designation of Rural Mountainous. This Linkage likely provides for movement of common mammals such as bobcat as well as Live-In Habitat for species listed in the table below. Since this is an existing Linkage with no new Reserve Assembly anticipated, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/ Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Existing Noncontiguous Habitat Block A

Existing Noncontiguous Habitat Block A consists of the Box Springs Mountains, located in the extreme northern region of the Plan Area. Existing Noncontiguous Habitat Block A includes two pieces of land connected to each other by Proposed Constrained Linkage 8. This habitat block is in turn connected to other MSHCP conserved lands via Proposed Constrained Linkage 7 and Proposed Linkage 4 (Reche Canyon). Although this habitat block has a relatively high P/A ratio (44 feet per acre) compared to the existing and proposed Core Areas, it is well connected overall and situated only 1.7 miles from Existing Core D. This habitat block provides Live-In Habitat for species, and it likely contains movement Habitat for common mammals such as bobcat. However, Existing Noncontiguous Habitat Block A is partially constrained by existing urban Development and is surrounded by a city planned land use designation. Potential alignment of the San Bernardino to Moreno Valley corridor may also affect movement and viability of species within the habitat block. As such, treatment and management of edge conditions along this habitat block will be necessary to ensure that it provides Habitat and movement functions for species using the habitat block. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Management entities in this existing Noncontiguous Habitat Block include the County of Riverside Park and Open Space District.

Existing Noncontiguous Habitat Block B

Existing Noncontiguous Habitat Block B consists of Bogart County Park, located in the northeastern portion of the Plan Area. This publicly-owned habitat block is connected to other MSHCP conserved lands via Proposed Constrained Linkage 23 (Cherry Valley Linkage). Existing urban Development and a Community Development planned land use designation constrain some margins of the block. Therefore, special care must be taken to maintain high quality Habitat within the Core and along the edges for species sensitive to Edge Effects listed in the table below. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Despite potential Edge Effect issues, this habitat block provides Live-In Habitat for a number of species as noted in the table below and possibly movement Habitat for other common mammals such as bobcat.

Existing Noncontiguous Habitat Block C

Existing Noncontiguous Habitat Block C is comprised of BLM land north of the Cahuilla Indian Reservation. This habitat block supports known populations of Quino checkerspot butterfly. Maintenance of habitat quality and connections to other areas supporting populations of Quino checkerspot butterfly is important for this species. As shown in the table below, approximately 550 acres of a total of 660 acres within this habitat block are not affected by edge. Since this is an existing Noncontiguous Habitat Block affected by edge with no new Reserve Assembly anticipated, management of edge conditions along the habitat block will be necessary to ensure that habitat quality is maintained and indirect effects of widening Cary Road (existing facility) and planned land uses are minimized. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Core 1

Proposed Core 1 is located approximately in the east-central region of the Plan Area. This Core Area consists largely of private lands in the Alberhill area but also contains small pieces of Public/Quasi-Public Lands. The Core exists in two blocks, one east and one west of I-15. Connections are made from the Core to Proposed Linkage 1, Proposed Linkage 2 (Alberhill Creek), Proposed Linkage 3, and Existing Core C (Lake Mathews/Estelle Mountain). The Core provides Habitat for species and also provides for movement of species. Key populations of coastal California gnatcatcher, Munz's onion, many-stemmed dudleya, cactus wren, tricolored blackbird, and yellow warbler are supported in this Core Area. The Core likely provides for movement of common mammals such as bobcat. Since this Core is contiguous with Existing Core C (Lake Mathews/ Estelle Mountain) via an approximately 10,000-foot connection, the functional area of the Core is much greater than 7,470 acres reported in the table below. Because a portion of the Core is surrounded by city (Lake Elsinore) and community Development planned land uses, and since this Core may be affected by the proposed Hemet to Corona/Lake Elsinore CETAP Corridor, management of edge conditions in these areas will be needed to maintain high quality Habitat within the Core. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Core 2

Proposed Core 2 (Antelope Valley) is located approximately in the southwest region of the Plan Area. This Core Area consists largely of private lands but also contains small pieces of Public/Quasi-Public Lands. Connections from the Core are made through Proposed Constrained Linkages 15 (Lower Warm Springs Creek), 16, 17 (Paloma Valley), and 18. The Core is constrained in all directions by existing agricultural uses and urban Development. Though the Core has one of the highest P/A ratios of all MSHCP proposed or existing Cores, it is highly connected to other MSHCP conserved lands and is located only 1.1 miles from the nearest connected Core, Existing Core J (Lake Skinner/Diamond Valley Lake). This Core provides important Habitat for the Quino checkerspot, which has key populations in this area. This butterfly is restricted by the distribution and availability of its hosts plants, which in many areas have been replaced by non-native exotic weed species and habitat type conversion. Because of the large number of Covered Activities planned in this area and the constrained condition of the Core, management of edge conditions will be necessary in this area to maintain high quality Habitat for the Qunio checkerspot and other species using this Core. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Core 3

Proposed Core 3 (Badlands/Potrero) is located in the northeast region of the Plan Area. This Core consists mainly of private lands but also contains a few Public/Quasi-Public parcels including De Anza Cycle Park. The Core is connected to Proposed Linkage 12 (north San Timoteo Creek), Proposed Linkage 4 (Reche Canyon), Proposed Constrained Linkage 22 (east San Timoteo Creek), Existing Core H (Lake Perris), Existing Core K (San Jacinto Mountains), Proposed Linkage 11 (Soboba/Gilman Springs), and Proposed Constrained Linkage 21. The Core also functions as a Linkage, connecting the San Bernardino National Forest to the southwest with San Bernardino County and other conserved areas to the north of the Core. With a total acreage of approximately 24,920 acres, Proposed Core 3 is one of the largest MSHCP Core Areas. In addition, the Core is contiguous with Existing Core H (Lake Perris/Mystic Lake) and Existing Core K (San Jacinto Mountains), thus greatly enlarging the functional area of the Core. The Core has both a large proportion of its area unaffected by edge (approximately 23,420 acres of the total 24,940 acres) and is only partially constrained by existing agricultural use. Within the Core, important Live-In and movement Habitat is provided for Bell's sage sparrow, loggerhead shrike, cactus wren, Stephens' kangaroo rat, southern California rufous-crowned sparrow, and mountain lion, which have key populations in the Badlands. Management of edge conditions will be necessary in the Badlands to maintain high quality Habitat for these species in areas which may be affected by covered facilities including Lambs Canyon Road, San Timoteo Canyon Road, and Gilman Springs Road. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Note: * This Core is contiguous with Existing Core H and Existing Core K.

Proposed Core 4

Proposed Core 4 (East Cactus Valley) is located in the east-central region of the Plan Area. This Core is composed of private lands and is generally unconstrained by existing urban Development or agricultural use. Connections are made from the Core via Existing Constrained Linkage D (Bautista Creek), Proposed Linkage 14 (Cactus Valley), and Existing Core K (San Jacinto Mountains). The Core also functions as a Linkage, connecting the Diamond Valley Lake/Lake Skinner and Cactus Valley areas in the west with the San Jacinto Mountains in the east. Proposed Core 4 is contiguous with Existing Core K (San Jacinto Mountains), thus greatly enlarging the functional area of the Core. The Core provides Live-In and movement Habitat for several species, including the Quino checkerspot, which has key populations in this area. As previously mentioned, this butterfly is restricted by the distribution and availability of its host plants, which in many areas have been replaced by non-native exotic weed species and habitat type conversion. However, due to the lack of planned roadway facilities, the large size of the Core (11,890 acres), and surrounding planned land uses largely of Rural Mountainous, these types of Edge Effects are not expected to compromise the integrity of the Core.

Proposed Core 5

Proposed Core 5 is comprised of the portion of the upper San Jacinto River extending from the San Jacinto Mountains to just west of State Street. It is contiguous with Core Areas in the San Jacinto Mountains and areas downstream along the San Jacinto River. Planning Species for which Habitat is provided within this Core include mountain yellow-legged frog, arroyo toad, least Bell's vireo, southwestern willow flycatcher, San Bernardino kangaroo rat, and Los Angeles pocket mouse. Maintenance of floodplain processes and water quality of the San Jacinto River is important for these species, as well as maintenance of habitat quality. This Core likely provides for movement of mammals such as mountain lion and bobcat, connecting to Core Areas in the San Jacinto Mountains, Lake Perris and San Jacinto Wildlife Refuge. In addition to indirect effects associated with adjacent planned land uses identified in Section 6.0 of this document, flood control activities resulting from adjacent planned land uses may also adversely affect species such as arroyo toad, San Bernardino kangaroo rat, least Bell's vireo, southwestern willow flycatcher and Los Angeles pocket mouse.

Proposed Core 6

Proposed Core 6 is comprised largely of the Silverado Ranch. It provides Habitat for a number of Planning Species such as Quino checkerspot butterfly, Stephens' kangaroo rat, Los Angeles pocket mouse, mountain lion and bobcat. As shown on the table below, areas not affected by edge within this proposed Core total approximately 4,060 acres of the total 4,290 acres of the Core. Maintenance of large intact interconnected habitat blocks is important for these species.

In addition to indirect effects of adjacent land uses described in Section 6.0 of this document, fire, fire suppression, and sheep and cattle grazing associated with Development adjacent to MSHCP Conservation Areas may adversely affect species listed in the table below. Other activities which may affect biological resources within the proposed Core include widening of existing roadways. The proposed roadway widening noted in the table below may result in habitat fragmentation and increased motor vehicle traffic may adversely affect Quino checkerspot butterfly during their flight season.

Proposed Core 7

Proposed Core 7 is comprised of a mosaic of upland and wetland habitat types in the Vail Lake, Sage and Wilson Valley areas. The proposed large intact habitat blocks provide Live-In Habitat for a number of Planning Species and movement for species connecting to other Core Areas located in the Agua Tibia Wilderness, San Bernardino National Forest and Beauty Mountain Management Area. This Core supports Quino checkerspot butterfly, coastal California gnatcatcher, Stephens' kangaroo rat, least Bell's vireo, bobcat, mountain lion and several Narrow Endemic Plant Species occurring on Travers-Willow-Domino soil series. Maintenance of large intact interconnected habitat blocks and wetland functions and values of Vail Lake and portions of Tucalota Creek, Temecula Creek, Tule Creek, Cottonwood Creek, Arroyo Seco Creek, Kolb Creek and Wilson Creek is important for these species. As shown on the table below, areas not affected by edge within this Core total approximately 48,510 acres of the total 50,000 acres occupied by this Core. For portions of Core Areas adjacent to Development, treatment and management of edge conditions will be necessary to ensure habitat quality for species using the Core.

Proposed widening activities may directly affect Habitat, floodplain processes along Temecula Creek important to the species noted above and in the table below, or may affect movement through this Core.

Proposed Noncontiguous Habitat Block 1

Proposed Noncontiguous Habitat Block 1 consists of two habitat blocks containing soils suitable for supporting the Delhi Sands flower-loving fly. This habitat block is constrained by existing adjacent agricultural activities. Maintenance of Delhi sands soil series is important for this species. As shown in the table below, areas not affected by edge within this habitat block total approximately 190 acres of the total 290 acres occupied by this proposed Noncontiguous Habitat Block. Because this species is adversely affected by agricultural activities such as grazing and discing, treatment and management of edge conditions will be necessary to maintain intact habitat blocks of Delhi sands. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

This Noncontiguous Habitat Block provides Habitat for Planning Species such as Delhi Sands flower-loving fly, loggerhead shrike, San Bernardino kangaroo rat and coastal California gnatcatcher. It may also provide a "stepping stone" for birds connecting to areas in San Bernardino County. Maintenance of large intact interconnected habitat blocks is important for these species. As shown in the table below, areas not affected by edge total approximately 1,070 acres of the total 1,230 acres occupied by this habitat block. Since this habitat block may be affected by edge, treatment and management of edge conditions will be necessary to ensure that it provides Habitat and movement functions for species using this habitat block.

Proposed Noncontiguous Habitat Block 3

Proposed Noncontiguous Habitat Block 3 consists of a habitat block containing soils suitable for supporting the Delhi Sands flower-loving fly. This habitat block is constrained by existing adjacent agricultural activities. Maintenance of Delhi Sands soil series is important for this species. As shown in the table below, areas not affected by edge within this habitat block total approximately 120 acres of the total 185 acres occupied by this proposed Noncontiguous Habitat Block. Because this species is adversely affected by agricultural activities such as grazing and discing, and by exotic invasive species, treatment and management of edge conditions will be necessary to maintain intact habitat blocks of Delhi Sands as adjacent planned community Development is developed along the edge of the habitat block. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Noncontiguous Habitat Block 4

Proposed Noncontiguous Habitat Block 4 is comprised of the Motte Rimrock Reserve. It provides Habitat for a number of Planning Species, including Quino checkerspot butterfly, coastal California gnatcatcher, and Stephens' kangaroo rat. Maintenance of large intact interconnected habitat blocks is important for these species. As shown in the table below, areas not affected by edge total approximately 920 acres of the total 1,150 acres occupied by this habitat block. Since this habitat block may be affected by edge, treatment and management of edge conditions will be necessary to ensure that it provides Habitat and movement functions for species using this habitat block as planned adjacent land uses are developed along the edge. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Activities associated with proposed adjacent land uses such as fire, fire suppression, off-road vehicle use and landscaping with exotic invasive species may be harmful to Stephens' kangaroo rat.

Proposed Noncontiguous Habitat Block 5

Proposed Noncontiguous Habitat Block 5 consists of the Lakeview Mountains, located approximately in the center of the Plan Area. This habitat block is connected to other MSHCP conserved lands via Proposed Constrained Linkage 20. The Lakeview Mountains are located 1.2 miles from the nearest connected Core (Existing Core H, Lake Perris/Mystic Lake). Private lands comprise the vast majority of lands in the habitat block, but a few small parcels of Public/ Quasi-Public Lands are also present. The Lakeview Mountains represent a large block of Habitat, which has a low P/A ratio and contains only 900 of the total approximately 7,150 acres as edge area. As such, this Noncontiguous Habitat Block supports the species listed in the table below, including a key population of Bell's sage sparrow. Since surrounding land uses include a substantial amount of city and agriculture, and one alternative for the Highway 79 Realignment Corridor would impact the habitat block, treatment and management of edge conditions in these affected areas will be necessary to ensure that it maintains high quality sage scrub Habitat, particularly for the Bell's sage sparrow. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Noncontiguous Habitat Block 6

Proposed Noncontiguous Habitat Block 6 consists of three vernal pools west of Hemet/San Jacinto, and east of the Lakeview Mountains. Though small in size, these parcels preserve important populations of Narrow Endemic Plant Species, including Davidson's saltscale, thread-leaved brodiaea, little mousetail, California Orcutt grass and spreading navarretia, as well as vernal pool fairy shrimp. Maintenance of vernal pool hydrology, water quality and Traver-Willow- Domino soil series is important for these species. Proposed Noncontiguous Habitat Block 6 is constrained by existing urban development and agricultural use. As shown in the table below, approximately 220 acres of the total 330 acres occupied by the vernal pools are not affected by edge. Adjacent urban Development in the City of San Jacinto, and realignment of the SR-79 North Corridor may affect resources within this habitat block. Treatment and management of edge conditions will be necessary to ensure that habitat quality and vernal pool hydrology are maintained as planned land uses are developed and major Covered Activities are implemented along the edge of this habitat block. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Noncontiguous Habitat Block 7

Proposed Noncontiguous Habitat Block 7 is comprised of a complex of vernal pools west of the City of Hemet. Though small in size and connected to other MSHCP lands solely via Existing Constrained Linkage B (Salt Creek), these parcels preserve important populations of Narrow Endemic Plant Species, including Davidson's saltscale, thread-leaved brodiaea, little mousetail, California Orcutt grass and spreading navarretia, as well as vernal pool fairy shrimp. Maintenance of vernal pool hydrology, water quality associated with Salt Creek and Traver-Willow-Domino soil series is important for these species. Proposed Noncontiguous Habitat Block 7 is constrained by existing urban Development and agricultural use. As shown in the table below, approximately 1,030 acres of the total 1,260 acres occupied by this habitat block are not affected by edge. Adjacent planned community Development, rural, urban Development in the City of Hemet, and expansion of existing facilities such as SR-74 and SR-79 may affect resources within this habitat block. Treatment and management of edge conditions will be necessary to ensure that habitat quality and vernal pool hydrology are maintained as planned land uses are developed along the edge of this habitat block.

Proposed Constrained Linkage 1

Proposed Constrained Linkage 1 is located in the northwest portion of the Plan Area. The Linkage connects Existing Core A (Prado Basin/Santa Ana River) with Existing Core B (Cleveland National Forest) to the south. Existing urban Development constrains the Linkage at its northern terminus; the Linkage is unconstrained in the south. In addition, SR91 intersects this Linkage at its northern border. Despite this, Proposed Constrained Linkage 1 likely provides for movement of mountain lion and bobcat from the Santa Ana Mountains to the Chino Hills area beyond the Plan Area. Maintenance of contiguous habitat blocks with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles in this proposed Linkage.

In addition, the Linkage has a relatively low P/A ratio (79 feet per acre) compared to other MSHCP Constrained Linkages, and the Linkage is surrounded by a Rural Mountainous planned land use designation. Thus Edge Effects will be somewhat mitigated by these factors. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. In addition, as SR-91 intersects the Linkage at its northern terminus, an adequate wildlife underpass or overpass may need to be implemented to insure movement of species in this area and to reduce the chance of mortality from vehicle collision.

Proposed Constrained Linkage 2

Proposed Constrained Linkage 2 consists of Fresno Canyon, located along the eastern border of the Plan Area. Like Proposed Constrained Linkage 1, this Linkage connects Existing Core A (Prado Basin and Santa Ana River) with Existing Core B (Cleveland National Forest) to the south. Unlike Constrained Linkage 1, however, the Fresno Canyon Constrained Linkage provides a riparian connection from the Prado Basin and Santa Ana River to the Cleveland National Forest, thus allowing for movement of species such as coast range newt and western pond turtle. This Linkage is also likely to be important for mountain lion movement from the Santa Ana Mountains to the Chino Hills beyond the Plan Area. Maintenance of contiguous habitat blocks with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles in this proposed Linkage.

Existing agricultural use and a small amount of urban Development constrain the Linkage along much of its length, and the vast majority of the Linkage is surrounded by a city (Corona) planned land use designation; thus treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. In addition, as SR-91 intersects the Linkage at its northern terminus, an adequate wildlife underpass or overpass may need to be implemented to insure movement of species in this area and to reduce the chance of mortality from vehicle collision.

Proposed Constrained Linkage 3

Proposed Constrained Linkage 3 is comprised of upland Habitat located in the vicinity of Indian Truck Trail. It provides movement of species between Core Areas along Temescal Wash and Lake Mathews/Estelle Mountain area to the Santa Ana Mountains in the Cleveland National Forest via an undercrossing of I-15. Although this Linkage is constrained by planned community Development. Planning Species such as bobcat may use this Linkage and maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles. As shown below, areas not affected by edge within this Linkage total approximately 20 acres of the total 80 acres of the Linkage. Since this Linkage is affected by edge, it is anticipated that treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides linkage area for species, such as bobcat moving through this area. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Habitat fragmentation or construction of barriers as a result of planned community Development may affect large mammal movement through this Constrained Linkage. Proposed widening of I-15 may also affect movement through this Constrained Linkage. Maintenance of an adequate wildlife undercrossing at least 10-20 feet wide with fencing and vegetative cover will be important to accommodate movement of bobcats.

Proposed Constrained Linkage 4

Proposed Constrained Linkage 4 is comprised of the portion of Temescal Wash extending from Indiana Avenue to El Cerrito Road. This Linkage provides Habitat for wetland species, Narrow Endemic Plant Species, and movement for species connecting to Core Areas in Lake Mathews/Estelle Mountain and areas upstream along Temescal Wash. The northern extent of this Linkage is constrained by existing Development in the City of Corona. Planning Species for which Habitat is provided within this Linkage include Parry's spine flower, peninsular spine flower, smooth tarplant, least Bell's vireo and southwestern willow flycatcher. Maintenance of habitat quality and floodplain processes along Temescal Wash are important for these species. As shown below, areas not affected by edge within this Linkage total approximately 160 acres of the total 380 acres of the Linkage. Since this Linkage is affected by edge, it is anticipated that treatment and management of edge conditions along the portion of this Linkage adjacent to urban Development in the City of Corona will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 5

Proposed Constrained Linkage 5 is a wildlife undercrossing located in the vicinity of I-15 and Horsethief Canyon Road. It provides a connection to Core Areas along Temescal Wash and in the Lake Mathews/Estelle Mountain area to ultimately the Santa Ana Mountains in the Cleveland National Forest. It augments a proposed Linkage north of Alberhill. It is constrained by planned community Development to the east and to the north along I-15. Maintenance of contiguous Habitat is important for these species. This Linkage likely provides for movement for mammals such as mountain lion and bobcat. Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles.

As shown below, areas not affected by edge within this Linkage total approximately 15 of the 25 acres of the Linkage. Since this Linkage is affected by edge, it is anticipated that treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Adjacent planned community Development and widening of I-15 may affect movement of species through this Constrained Linkage.

Proposed Constrained Linkage 6

Proposed Constrained Linkage 6 is located approximately in the east-central region of the Plan Area and consists of a portion of Temescal Wash. This Linkage connects Proposed Core 1 (Alberhill), Proposed Extension of Existing Core 2 (Lake Mathews/Estelle Mountain Extension), and Proposed Linkage 1. Private lands comprise the entirety of the Linkage, which provides important upland and riparian Habitat for species such as those listed in the table below. High quality riparian Habitat must be maintained within the Core and along the edges for species such as Cooper's hawk, yellow warbler, white-tailed kite, yellow-breasted chat and least Bell's vireo, which have key populations located in or along the wash. Since existing agricultural use completely constrains this Linkage, and the Linkage is partially surrounded by community Development planned land use, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 7

Proposed Constrained Linkage 7 is comprised of upland Habitat in the vicinity of Central Avenue. It is the only connection from Sycamore Canyon Park to Box Springs Reserve. This Linkage is important for species dispersal and would reduce the likelihood of species extinction as a result of population isolation. Habitat for Planning Species such as cactus wren and Bell's sage sparrow occurs within this Linkage. This Linkage likely provides for movement of common mammals such as bobcat. Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles.

As shown in the table below, areas not affected by edge within this Linkage total approximately 65 acres of the total 175 acres of the Linkage. Since this Linkage is affected by edge, it is anticipated that treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. The Linkage is constrained by existing urban Development and roadways. Adjacent planned community Development, urbanized areas of the City of Riverside and proposed widening activity of I-215 may affect bobcat movement through this Constrained Linkage. Maintenance of an adequate wildlife undercrossing at least 10-20 feet wide with fencing and vegetative cover will be important to accommodate bobcat movement.

This Linkage is constrained by planned Rural Mountainous Development to the north. Since this Linkage is affected by edge, it is anticipated that treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 9

Proposed Constrained Linkage 9 is one of four Constrained Linkages connecting the Santa Rosa Plateau and Tenaja Corridor to San Diego County. It provides an upland connection to the Cleveland National Forest and areas in San Diego County via the Tenaja Corridor for large mammals. This connection may serve as one component of a larger movement corridor for mountain lions traveling between the Santa Ana Mountains and the Palomar Mountains. A Linkage between these two mountain ranges would reduce the risk of extirpation of the Santa Ana Mountains population of mountain lion, which was considered to be "demographically unstable" without a movement connection (Beier 1993). Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles. This Linkage also may serve as foraging Habitat for raptors and other wildlife species noted in the table below.

Since this Constrained Linkage is affected by edge, it is anticipated that management of edge conditions will be necessary to ensure that this Linkage maintains movement of large mammals. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. This Linkage is constrained by surrounding planned Rural Mountainous land uses. Any barriers, including roadways and fencing, associated with adjacent planned Rural Mountainous land uses may result in fragmentation of this Constrained Linkage and affect wildlife movement.

Proposed Constrained Linkage 10

Proposed Constrained Linkage 10 is one of four Constrained Linkages connecting the Santa Rosa Plateau and Tenaja Corridor to San Diego County. It provides an upland connection to the Cleveland National Forest and areas in San Diego County via the Tenaja Corridor for large mammals. This connection may serve as one component of a larger movement corridor for mountain lions traveling between the Santa Ana Mountains and the Palomar Mountains. A Linkage between these two mountain ranges would reduce the risk of extirpation of the Santa Ana Mountains population of mountain lion, which was considered to be "demographically unstable" without a movement connection (Beier 1993). Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles. This Linkage also may serve as foraging Habitat for raptors and other wildlife species noted in the table below.

As shown in the table below, approximately 100 acres of a total 105 acres within this Constrained Linkage is affected by edge. Upon Reserve Assembly of this proposed Constrained Linkage, management of edge conditions will be necessary to ensure that this Linkage maintains movement of large mammals. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. It is constrained by surrounding planned Rural Mountainous land use. Any barriers, including roadways and fencing, associated with adjacent planned Rural Mountainous land uses may result in fragmentation of this Constrained Linkage and affect wildlife movement.

Proposed Constrained Linkage 11

Proposed Constrained Linkage 11 consists of De Luz Canyon, located along the southwestern border of the Plan Area. The Linkage is composed of a west fork and an east fork, which connect San Diego County in the south to Proposed Linkage 9 (Tenaja Corridor) and Existing Core F (Santa Rosa Plateau Nature Reserve), respectively. The west route, from Proposed Linkage 9 to San Diego County, is approximately 15,850 feet (3.0 miles) in length, while the east route, from Existing Core F to San Diego County, is approximately 18,980 feet (3.6 miles) in length. This Constrained Linkage contains a very high proportion of its area (approximately 250 of the total 260 acres) defined as "edge" area and has one of the highest P/A ratios of all Constrained Linkages. Furthermore, the Linkage is constrained for the majority of its length by existing agricultural use. For these reasons care must be taken to maintain high quality Habitat along the edges for species sensitive to Edge Effects listed in the table below. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1.4 of this document.

Despite potential Edge Effect issues, this Linkage provides Live-In Habitat for a number of species as noted in the table below and possibly movement Habitat for mammals such as bobcat and mountain lion. This connection may serve as one component of a larger movement corridor for mountain lions traveling between the Santa Ana Mountains and the Palomar Mountains. A Linkage between these two mountain ranges would reduce the risk of extirpation of the Santa Ana Mountains population of mountain lion, which was considered to be "demographically unstable" without a movement connection (Beier 1993). Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles.

Proposed Constrained Linkage 12

Proposed Constrained Linkage 12 (Sandia Canyon) is located along the southwestern border of the Plan Area, just east of Proposed Constrained Linkage 11 (De Luz Canyon). Like Proposed Constrained Linkage 11, Proposed Constrained Linkage 12 is composed of a west fork and an east fork. Only the west fork, however, is connected to other MSHCP lands (Existing Core F, Santa Rosa Plateau Nature Reserve). The Linkage provides important Live-In Habitat for many species as noted in the table below and also likely provides an upland connection to the Cleveland National Forest and areas in San Diego County via the Tenaja Corridor for large mammals. This connection may serve as one component of a larger movement corridor for mountain lions traveling between the Santa Ana Mountains and the Palomar Mountains. A Linkage between these two mountain ranges would reduce the risk of extirpation of the Santa Ana Mountains population of mountain lion, which was considered to be "demographically unstable" without a movement connection (Beier 1993). Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles.

Although existing agricultural use constrains the Linkage and the Linkage's P/A ratio is somewhat large (196 feet per acre), the Linkage contains 170 acres of interior area, and surrounding planned land uses consist almost entirely of Rural Mountainous. Treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 13

Proposed Constrained Linkage 13 consists of Murrieta Creek, located in the southwestern region of the Plan Area. This Constrained Linkage connects Existing Core F (Santa Rosa Plateau Ecological Reserve) in the north to Proposed Linkage 10 in the south. This Linkage is constrained along most of its length by existing urban Development and agricultural use and the planned land use surrounding the Linkage consists of city (Murrieta and Temecula). Therefore, care must be taken to maintain high quality riparian Habitat within the Linkage and along the edges for species such as yellow warbler, yellow-breasted chat, and least Bell's vireo, which have key populations located in or along the creek. Maintenance of existing floodplain processes and water quality along the creek is also important to western pond turtle and arroyo chub in this area. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1.4 of this document.

Proposed Constrained Linkage 14 consists of portions of Pechanga and Temecula Creeks, located in the southwestern region of the Plan Area. This Constrained Linkage connects Existing Core G (Santa Margarita Ecological Reserve) and Proposed Linkage 10 in the west to Existing Linkage A in the south. This Linkage bifurcates and may be used to move directly to the east, along Temecula Creek, or to the southeast, along Pechanga Creek to Existing Linkage A. This Linkage is constrained along most of its length by existing urban Development and the planned land uses surrounding the Linkage consist almost entirely of city (Temecula). I-15 also intersects the Linkage at its western terminus. Therefore, high quality Live-In riparian Habitat must be maintained, and movement Habitat for bobcat and mountain lion must be provided, as these species are known to use the Linkage for movement. This portion of Pechanga and Temecula Creek may serve as one component of a larger movement corridor for mountain lions traveling between the Santa Ana Mountains and the Palomar Mountains. A Linkage between these two mountain ranges would reduce the risk of extirpation of the Santa Ana Mountains population of mountain lion, which was considered to be "demographically unstable" without a movement connection (Beier 1993). Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles. Maintenance of existing floodplain processes and water quality along the creek is also important for wetland species noted in the table below.

Proposed Constrained Linkage 15

Proposed Constrained Linkage 15 is located in the southwestern region of the Plan Area. This Constrained Linkage consists of a portion of Lower Warm Springs Creek, from just east of the I-15 freeway to Proposed Core 2 (Antelope Valley). The Linkage provides Live-In Habitat for species such as western pond turtle and Los Angeles pocket mouse and also provides important linkage area for bobcat. This Linkage contains one of the highest P/A ratios of all MSHCP Constrained Linkages (160 feet per acre), and contains a relatively small proportion of its area as interior area (approximately 30 acres of the total 180 acres). In addition, existing urban Development constrains much of the Linkage, and planned land uses surrounding the Linkage include city (Murrieta) and community Development. For these reasons, special care must be taken to maintain high quality Habitat within the Linkage and along the edges for species sensitive to Edge Effects. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 16

Proposed Constrained Linkage 16 is located approximately in the south-central region of the Plan Area. This Constrained Linkage consists of an unnamed blueline drainage connecting Proposed Linkage 8 in the west with Proposed Core 2 (Antelope Valley) in the east. The Linkage provides Habitat for species and also provides for movement of species. The Linkage likely provides for movement of common mammals such as bobcat. Existing urban Development and agricultural use constrain the Linkage along its entire length, and the Linkage is completely surrounded by a city-designated planned land use. Species movement through the Linkage may also be affected by the intersection of the Linkage with I-215. Therefore, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 17

Proposed Constrained Linkage 17 (Paloma Valley) is located in the south-central region of the Plan Area. Proposed Extension of Existing Core 7 (Lake Skinner/Diamond Valley Lake Extension) is located to the east of this Linkage. The Linkage provides Habitat for species and also provides for movement of species. Although this Linkage is constrained by existing urban Development and agricultural use along much of its length, planned land uses surrounding the Constrained Linkage are nearly entirely rural. In addition, the Constrained Linkage has a comparatively low P/A ratio. Thus, Edge Effects on this Constrained Linkage may be substantially lower than for other Constrained Linkages. Nonetheless, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage, since several major Covered Activities are proposed for extension or widening within or adjacent to the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. An adequate wildlife underpass or overpass may need to be implemented to insure movement of species in this area and to reduce the chance of mortality from vehicle collision.

Proposed Constrained Linkage 18

Proposed Constrained Linkage 18 consists of an unnamed drainage located in the south-central region of the Plan Area. This Constrained Linkage connects Proposed Core 2 (Antelope Valley) to the west with Proposed Extension of Existing Core 7 (Lake Skinner/Diamond Valley Lake Extension). Existing agricultural use constrains the Linkage, and planned land uses surrounding the Linkage are limited nearly entirely to community Development. The Linkage also has a relatively high proportion of land affected by edge (approximately 250 acres of the total 310 acres) and will also be subject to Edge Effects also due to the widening or extension of several facilities including Washington Street, Briggs Road, and SR-79. Despite these issues, the Linkage nonetheless provides Live-In and movement Habitat for species. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. This Linkage likely provides for movement of common mammals such as bobcat. An adequate wildlife underpass or overpass may need to be implemented to insure movement of species in this area and to reduce the chance of mortality from vehicle collision.

Proposed Constrained Linkage 19

Proposed Constrained Linkage 19 (Lower San Jacinto River) is located approximately in the center of the Plan Area. This Constrained Linkage connects Proposed Linkage 7 in the southwest with Proposed Extension of Existing Core 4 (San Jacinto River Core) in the northeast. Existing agricultural use and a small amount of existing urban Development constrain the Linkage along much of its length. Surrounding planned land uses include only city (Perris). Although the river will be channelized for flood control in this area, the Linkage will nonetheless maintain connectivity along the river and provide for movement of common mammals such as bobcat. An adequate wildlife underpass or overpass may need to be implemented to insure movement of species in this area and to reduce the chance of mortality from vehicle collision. Treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage and that wetland functions and values are maintained for the benefit of Narrow Endemic Plant Species known to occur in the San Jacinto River. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Constrained Linkage 20

Proposed Constrained Linkage 20 is located approximately in the north-central region of the Plan Area. This Linkage connects Existing Core H (Lake Perris) in the north with Proposed Noncontiguous Habitat Block 5 (Lakeview Mountains) in the south. Maintenance of this connection is important to reduce the likelihood of species extirpation as a result of population isolation for species occurring in the Lakeview Mountains. Existing agricultural use completely constrains this Linkage, and the proposed General Plan land use designation surrounding the Linkage is entirely agriculture. The extension/widening of Bridge Street and the proposed alignment of the Hemet to Corona/Lake Elsinore CETAP Corridor may also compromise the integrity of Proposed Constrained Linkage 20 by adding to Edge Effects contributed by surrounding land use practices. Counteracting these potentially strong Edge Effects, however, are the dimensions of this Linkage. The Linkage has one of the lowest P/A ratios (60 feet per acre) of all MSHCP Cores and Linkages and a high proportion of its area represented as interior (approximately 270 of the total 360 acres). Thus the Linkage can be expected to provide Live-In and movement Habitat for the species listed in the table below. Nevertheless, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Maintenance of wetland functions and values is important for Narrow Endemic Plant Species known to occur in the Lake Perris/Mystic Lake area.

Proposed Constrained Linkage 21

Proposed Constrained Linkage 21 is comprised of riparian and alluvial fan sage scrub Habitats connecting the upper San Jacinto River to the southern Badlands. It provides Live-In Habitat for certain species and serves as a connection to Core Areas in the Badlands and the San Jacinto River. The Linkage is constrained by Gilman Springs Road on the northern end of the Linkage and proposed General Plan land use designation, Community Development, along Gilman Spring Road to the west of the Linkage. Planning Species for which Habitat is provided within this Linkage include bobcat, Stephens' kangaroo rat, Belding's orange-throated whiptail, San Bernardino kangaroo rat, and Los Angeles pocket mouse. In addition to maintenance of habitat quality, maintenance of floodplain processes along the upper San Jacinto River is important for these species. This Linkage likely provides for movement of common mammals such as bobcat. As shown below, areas not affected by edge within this Linkage total approximately 140 acres of the total 185 acres of the Linkage. Upon Reserve Assembly of this proposed Constrained Linkage, management of edge conditions will be necessary to ensure maintenance of floodplain processes and movement of mammals through this Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Habitat fragmentation or construction of barriers as a result of planned community Development may affect large mammal movement through this Constrained Linkage, and any flood control or alteration of hydrology associated with widening of Gilman Springs Road may affect Habitat supporting arroyo toad and San Bernardino kangaroo rat. Adequate wildlife crossings may be needed to facilitate wildlife movement across Gilman Springs Road.

Proposed Constrained Linkage 22

Proposed Constrained Linkage 22 is comprised of the portion of San Timoteo Creek extending west from I-10 to De Anza Cycle Park. This Linkage provides Habitat for certain species and a connection to Core Area in the Badlands. This Linkage is constrained by I-10 to the east, San Timoteo Canyon Road and railroad tracks to the north, SR-60 to the south, and by existing agricultural land uses within the City of Beaumont. Planning Species for which Habitat is provided for within this Linkage include least Bell's vireo and Los Angeles pocket mouse. In addition to maintenance of habitat quality, maintenance of floodplain processes along the San Timoteo Creek is important for this species. This Linkage likely provides for movement of common mammals such as bobcat. As shown below, areas not affected by edge within this Linkage total approximately 260 acres of the total 400 acres. Upon Reserve Assembly of this proposed Constrained Linkage, management of edge conditions will be necessary to ensure maintenance of floodplain processes and movement of mammals through this Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Flood control or alteration of hydrology associated with land use activities in the City of Beaumont and with widening of major existing roadways may affect Habitat supporting least Bell's vireo and Los Angeles pocket mouse.

Proposed Constrained Linkage 23

Proposed Constrained Linkage 23 is an upland Linkage located in the vicinity of Cherry Valley, which provides a connection to Bogart County Park and San Timoteo Creek for certain species. This Linkage is constrained by surrounding existing urban and rural residential Development in the City of Calimesa. Planning Species for which Habitat is provided within this Linkage include Bell's sage sparrow, Los Angeles pocket mouse, and San Bernardino mountain kingsnake. Maintenance of a contiguous connection is important for these species. This Linkage likely provides for movement of common mammals such as bobcat. As shown below, areas not affected by edge within this Linkage total approximately 860 acres of the total 1,410 acres. Upon Reserve Assembly of this proposed Constrained Linkage, management of edge conditions will be necessary to provide movement of mammals through this Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Barriers, including roadways and fencing constructed as part of adjacent Development, may result in fragmentation of the Linkage and affect movement through the Linkage by mammals such as bobcats.

Proposed Constrained Linkage 24

Proposed Linkage 24 is comprised of the portion of Temecula Creek east of Redhawk Parkway and west of Pauba Road. This Linkage provides Habitat for wetland species and a connection to Core Areas in Wilson Valley. The Linkage is constrained by existing roadways and planned community Development. Planning Species for which Habitat is provided for within this Linkage include bobcat, mountain lion, Stephens' kangaroo rat, Aguanga kangaroo rat, western pond turtle, yellow warbler, southwestern willow flycatcher, arroyo chub, loggerhead shrike, tree swallow, white-tailed kite, Cooper's hawk and least Bell's vireo. In addition to maintenance of habitat quality, maintenance of existing floodplain processes along Temecula Creek is important for these species. While specific studies of movement along this Linkage have not been conducted, it likely provides for movement of common mammals such as bobcat. As shown below, areas not affected by edge within this Linkage total approximately 110 acres of the total 340 acres of the Linkage. Since this is an existing Constrained Linkage already affected by edge, treatment and management of edge conditions along this Linkage will be necessary to ensure that it provides Habitat and movement functions for species using the Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Community Development, Agricultural and Rural Pauba Road

Pauba Road is an existing road that is proposed to be widened. Proposed widening activities may directly affect Habitat or floodplain processes in Temecula Creek, or may affect movement through this Linkage. Pauba Road crosses Temecula Creek under existing conditions and would continue to cross the creek with proposed widening. Adequate wildlife crossing may be needed to facilitate wildlife movement across Pauba Road.

Proposed Linkage 1

Proposed Linkage 1 consists of the foothills of the Santa Ana Mountains just west of Lee Lake in the west-central region of the Plan Area. The Linkage is contiguous with Existing Core B (Santa Ana Mountains) to the west, Proposed Constrained Linkages 5 (Horsethief Canyon) and 6 (Temescal Wash South) and Proposed Extension of Existing Core 2 (Lake Mathews/Estelle Mountain) to the north, and Proposed Core 1 (Alberhill) to the east. Both Live-In and movement Habitat are provided by the Linkage. Several different routes, ranging from 5,400 to 14,950 feet, may be taken through the Linkage to surrounding MSHCP Conservation Area lands. This Linkage likely provides for movement of common mammals such as bobcat. Mountain lions are also likely to use the Linkage to access Core Areas in the Lake Mathews/Estelle Mountain Reserve. Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juveniles. Since existing urban Development constrains much of the Linkage, and surrounding planned land uses include city (Lake Elsinore) and community center, management of Edge Effects in this area will be necessary. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Linkage 2

Proposed Linkage 2 is comprised of wetland Habitat associated with Collier Marsh in the City of Lake Elsinore. It supports key populations of the following species: yellow-breasted chat, San Diego ambrosia, downy woodpecker, least Bell's vireo, yellow warbler and southwestern willow flycatcher. Maintenance of wetland functions and values and water quality of Collier Marsh is important for these species. As shown below, areas not affected by edge within this Linkage total approximately 70 acres of the total 160 acres occupied by this Linkage. Since this Linkage may be affected by edge, treatment and management of edge conditions will be necessary to ensure that land uses adjacent to the Linkage do not degrade water quality or inhibit floodplain processes. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Linkage 3

Proposed Linkage 3 is generally comprised of upland Habitats in the Gavilan Hills, Harford Springs and proposed North Peak Conservation Bank area under Public/Quasi-Public and private ownership. This Linkage is one of two connections between the Lake Mathews/Estelle Mountain Reserve and Core Areas in Alberhill. Planning Species for which Habitat is provided for within the Linkage include coastal California gnatcatcher, Quino checkerspot butterfly, and Stephens' kangaroo rat. The Linkage also contains clay soils capable of supporting sensitive plant species such as thread-leaved brodiaea, Munz's onion and many-stemmed dudleya. This Linkage likely provides for movement of common mammals such as bobcat, connecting to Core Areas in Lake Mathews/Estelle Mountain and Alberhill. Maintenance of large intact interconnected habitat blocks is important for these species, as well as Conservation of clay soils supporting sensitive plant species. This Linkage is generally unconstrained by existing urban Development or agricultural use. As shown on the table below, 4,620 acres of the total 5,550 acres occupied by the Linkage are not affected by edge. No major Covered Activities are planned to be located within this Linkage; however, adjacent planned land uses, which generally consists of rural Development, may affect resources within the Linkage. Fire, fire suppression, livestock grazing, and off-road vehicle activities associated with the rural land uses may result in adverse Edge Effects. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Linkage 4

Proposed Linkage 4 is comprised of generally upland Habitat in Reche Canyon. Planning Species for which Habitat is provided for within the Linkage include Bell's sage sparrow, Stephens' kangaroo rat, bobcat, and Nevin's barberry, known to occur within chaparral and coastal sage scrub Habitats. This Linkage likely provides for movement of common mammals such as bobcat, connecting to Box Springs Reserve, the Badlands and San Bernardino County. The Reche Canyon area represents one of the largest intact Core Areas within the MSHCP Plan Area; therefore maintenance of existing large habitat blocks is important for species and reserve design. The Linkage is relatively unconstrained by adjacent planned Rural Mountainous land uses. Major Covered Activities intersecting the Linkage include the San Bernardino to Moreno Valley CETAP Corridor and Reche Canyon Road. Widening of existing Reche Canyon Road will need to consider wildlife crossings as part of the design.

Proposed Linkage 6 is an upland Linkage connecting San Timoteo Creek and Core Areas in the Badlands to San Bernardino County. It provides Habitat for raptors and movement for species, such as bobcat, connecting to San Bernardino County and San Timoteo Creek. Maintenance of large intact contiguous habitat blocks is important for these species. As shown below, areas not affected by edge within this Linkage total approximately 490 acres of the total 545 acres occupied by this Linkage. Since this Linkage may be affected by edge, treatment and management of edge conditions will be necessary to ensure that it provides Habitat and movement functions for species using this Linkage. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Linkage 7

Proposed Linkage 7 consists of a patchwork of riparian Habitat associated with the San Jacinto River and Canyon Lake and adjacent upland Habitat occurring within Kabian Park, Canyon Lake, and Four Seasons Conservation Land. Similar to Proposed Linkage 8, this Linkage is a major component of one of the two main east-west connections within the MSHCP Plan Area. The Linkage provides for movement of species connecting to Sedco Hills, Alberhill and to areas upstream along the San Jacinto River. Planning Species for which Habitat is provided for within the Linkage include Bell's sage sparrow, coastal California gnatcatcher, least Bell's vireo, and bobcat. The Linkage also contains the Traver-Willow-Domino soils series, which is capable of supporting several Narrow Endemic Plant Species such as San Jacinto Valley crownscale, vernal barley and spreading navarretia. Maintenance of large intact interconnected habitat blocks is important for these species, as well as maintenance of water quality and existing functions and values of wetland Habitats associated with the the San Jacinto River. As shown on the table below, 2,560 acres of the total 3,400 acres occupied by the Linkage are not affected by edge.

Adjacent planned land uses and major Covered Activities traversing the Linkage, noted in the table below, may affect resources within the Linkage. Adjacent planned land uses generally consist of Community Development and City (Perris, Lake Elsinore and Canyon Lake). The areas within these Cities that are adjacent to the Linkage are generally characterized as urban and rural residential land uses. Land use activities within either the City or Community Development designation, may result in Edge Effects associated with fire suppression, fire, and dispersal of invasive species. Major Covered Activities may also contribute additional Edge Effects such as trash and runoff and result in habitat fragmentation. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Construction of the proposed Hemet to Corona/Lake Elsinore CETAP Corridor Alternative 5A and 5E along SR-74 (Ethanac Road) may isolate the Linkage from Core Areas upstream along the San Jacinto River. Improvements to this facility will need to consider a terrestrial crossing for wildlife and maintenance of the hydrology of the San Jacinto River.

Proposed Linkage 8 (Sedco Hills/Wildomar) is composed largely of upland Habitat in the Sedco Hills and Wildomar area. This Linkage is a major component of one of the two main east-west connections between Core Areas in the Lake Mathews/Estelle Mountain, Alberhill and the Cleveland National Forest in the western portion of the MSHCP Plan Area and Core Areas in French Valley, Johnson Ranch, Diamond Valley Lake and San Jacinto Mountains in the eastern portion of the MSHCP Plan Area. This Linkage provides Live-In Habitat for over 50 pairs of coastal California gnatcatcher, as well as a connection to other key populations of gnatcatcher known to occur in Alberhill, North Peak and the Ramsgate area. Other Planning Species for which Habitat is provided include Quino checkerspot butterfly, Stephens' kangaroo rat, and bobcat. The grasslands occurring within this proposed Linkage also provide foraging Habitat for a number of raptors. Maintenance of large intact interconnected habitat blocks is important for these species. The northern portion of this Linkage includes a portion of the lower San Jacinto River extending under I-15 to connect with Proposed Extension of Existing Core 3.

As shown on the table below, 4,560 acres of the total 5,470 acres occupied by the Linkage is not affected by edge. Adjacent planned land uses and major Covered Activities traversing the Linkage may affect resources within the Linkage. Adjacent planned land uses generally consist of Community Development and Agriculture. Land use activities within either designation may result in Edge Effects associated with fire suppression, fire, and dispersal of invasive species. Major Covered Activities may also contribute additional Edge Effects such as trash and runoff and result in fragmentation of habitat blocks. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. Widening of I-215, which abuts this Linkage to the east, may isolate the Linkage from Core Areas in French Valley. Improvements to this facility will need to consider both an avian crossing and terrestrial crossing for wildlife. Widening of I-15 will need to consider maintenance of wildlife movement along the lower San Jacinto River.

This Linkage likely provides for movement of common mammals such as bobcat, connecting to Core Areas in Lake Mathews/Estelle Mountain and Alberhill. Coastal California gnatcatcher may use the Linkage to disperse to other Core Areas supporting gnatcatchers, such as the Hogbacks and Alberhill. Because the coastal California gnatcatcher has lower dispersal capabilities than other small passerine birds, the dispersal of juveniles requires a corridor of native vegetation which provides foraging and cover opportunities to link larger patches of appropriate sage scrub vegetation (Soule 1991).

Proposed Linkage 9

Proposed Linkage 9 is comprised of a mosaic of upland and wetland Habitats in the area known as the Tenaja Corridor. This Linkage provides Live-In Habitat for a number of Planning Species and movement for species connecting to Core Areas in the Santa Rosa Plateau or to the Santa Ana Mountains in the Cleveland National Forest. Planning Species for which Habitat is provided for within this Linkage include three fairy shrimp species. Maintenance of water quality in this Linkage and the watershed supporting the vernal pools is important for these species. This Linkage also provides for movement of species, including mountain lion and bobcat, through the Tenaja Corridor to the Santa Rosa Plateau and the Cleveland National Forest. Maintenance of habitat quality and large contiguous Habitat with appropriate refugia for resting, such as rockpiles, brushpiles, windfalls, hollow snags and hollow trees, is important for dispersal of juvenile bobcat and mountain lion. As shown below, areas not affected by edge within this Linkage total approximately 2,730 acres of the total 3,100 acres occupied by this Linkage. Habitat fragmentation or construction of barriers as a result of planned Rural Mountainous Development may affect large mammal movement through this Linkage.

Proposed Linkage 10

Proposed Linkage 10 consists of an upland connection in the southwest region of the Plan Area extending from Existing Core F (Santa Rosa Plateau Ecological Reserve) in the north to Existing Core G (Santa Margarita Ecological Reserve) in the south. Private lands compose the entirety of the Linkage, which consists of upland Habitat complementary to the riparian Linkage provided between these two Cores by Proposed Constrained Linkage 13 (Murrieta Creek). This Linkage, which is only somewhat constrained by existing urban Development, provides for movement between these two Cores for species such as bobcat and mountain lion. Although the Linkage is somewhat lengthy at 5.5 miles, it is also nearly a mile wide and thus provides Live-In Habitat for many species. Surrounding planned land uses are approximately evenly divided between Rural Mountainous and city (Murrieta, Temecula). In areas of the Linkage bordering Cities, treatment of edge conditions will be necessary to maintain the proper Habitat and movement functions of the Linkage.

Proposed Linkage 11

Proposed Linkage 11 (Soboba/Gilman Springs) is located in the northeastern section of the Plan Area. This Linkage connects to Proposed Core 3 (Badlands/Potrero) in the north, Existing Core K (San Jacinto Mountains) in the southeast, and Proposed Core 5 (Upper San Jacinto River) to the southwest. Private lands compose the entirety of the Linkage, which is only somewhat constrained by existing urban Development. This Linkage likely provides for movement of common mammals such as bobcat and may be an important Linkage area for mountain lions moving between the Badlands and the San Jacinto Mountains. Tributaries to the San Jacinto River occur within this Linkage that support arroyo toad and Los Angeles pocket mouse.

A low proportion of the area of the Linkage is affected by edge (approximately 190 acres of the total 1,670 acres), and the Linkage is 6,020 feet wide; thus Proposed Linkage 11 provides Live-In Habitat for many species in addition to movement Habitat. Nonetheless, management of edge conditions along the Linkage will be necessary due to surrounding planned land uses and possible effects of planned facilities such as Soboba Road. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document. A terrestrial crossing for mammals and reptiles may need to be considered at Soboba Road.

Proposed Linkage 12

Proposed Linkage 12 is comprised of riparian Habitats associated with San Timoteo Creek. Planning Species which use this Linkage include yellow warbler, white-tailed kite, yellow-breasted chat, least Bell's vireo, and Los Angeles pocket mouse. This Linkage likely provides for movement of common mammals such as bobcat connecting to San Bernardino County and Core Areas in the Badlands. Maintenance of habitat quality and wetland functions and values of San Timoteo Creek are important for these species.

As shown on the table below, 1,340 acres of the total 1,530 acres occupied by the Linkage are not affected by edge. This Linkage is relatively unconstrained by adjacent land uses, which include planned Rural Mountainous land uses and rural portions of the City of Calimesa. Widening of San Timoteo Creek may affect resources within the Linkage by contributing to Edge Effects such as runoff and trash. Improvements to this Covered Activity should be conducted away from the creek to conserve wetland functions and values. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

Proposed Linkage 13

Proposed Linkage 13 is comprised of Tucalota Creek and adjacent upland Habitats. It is one of two Linkages connecting Core Areas in Diamond Valley Lake, Lake Skinner and Johnson Ranch to Core Areas in the eastern portion of the MSHCP Plan Area. Because this Linkage is generally unconstrained by existing urban development or agricultural use, the Linkage provides Live-In Habitat for several Planning Species, including Quino checkerspot butterfly and Stephens' kangaroo rat . The Linkage also provides a connection for coastal California gnatcatcher, southwestern willow flycatcher, and bobcat, connecting to Core Areas in Diamond Valley Lake, Lake Skinner, and Wilson Valley. Maintenance of habitat quality, intact interconnected habitat blocks and wetland functions and values of Tucalota Creek are important for these species. As shown on the table below, 1,570 acres of the total 1,910 acres occupied by the Linkage are not affected by edge. No major Covered Activities are planned to be located within this Linkage; however, adjacent planned land uses, which generally consists of rural and Rural Mountainous Development may affect resources within the Linkage. Fire, fire suppression, livestock grazing, and off-road vehicle activities associated with these land use designations may result in adverse Edge Effects. Guidelines Pertaining to Urban/Wildlands Interface for the management of edge factors such as lighting, urban runoff, toxics, and domestic predators are presented in Section 6.1 of this document.

3.3 AREA PLANS

3.3.1 Introduction to Area Plans

As discussed in Section 3.1 of this document, the MSHCP is a criteria-based plan and identification of planning units on which to base the Criteria is necessary for such a criteria-based plan. The County's General Plan Area Plan boundaries were selected to provide the broad organizational framework for the Criteria (Figure 2-5). While these boundaries are not biologically based, they related specifically to County planning boundaries and to the boundaries of incorporated Cities within the MSHCP Plan Area. The Area Plan framework for the criteria-based approach was selected to structure implementation strategies around established planning boundaries.

Methods

For each Area Plan within the MSHCP Plan Area, the following methodology was applied. The approach is primarily map-based and relies on existing data compiled for species and Vegetation Communities as well as conservation biology principles. Information obtained during the habitat assessment workshops, additional communications with the Wildlife Agencies and local biologists regarding biological issues and conservation priorities, and specific project information obtained from various sources were also used in the Criteria development process.

The first steps in preparation of the Area Plan Criteria involved identification of: (1) Planning Species; (2) Biological Issues and Considerations; and (3) reserve configuration and management issues. For each Area Plan, several wildlife and plant species known to occur within the Area Plan were selected as Planning Species to provide guidance for Conceptual Reserve Design. Listed species and species with specific habitat requirements, such as Bell's sage sparrow (requires large patches of undisturbed Habitat) or bobcat (requires ability for movement with less tolerance to human presence than other species such as coyote), were generally selected as Planning Species. Biological Issues and Considerations, such as maintenance of key habitat blocks or Linkages, were also identified for each Area Plan. The Planning Species and Biological Issues and Considerations for each Area Plan Subunit are identified in the Area Plan texts included in Sections 3.3.2 through 3.3.17 of this document. Reserve configuration issues were generally addressed on a Plan Area wide basis and are incorporated in the Description of the MSHCP Conservation Area in Section 3.2 and in the discussion of Cores and Linkages in that section. In each Area Plan text, applicable Cores and Linkages are identified. Other general reserve configuration and management issues were also considered as appropriate for each Area Plan including the following:

  • representativeness of the applicable Bioregion(s) within the particular Area Plan;
  • representativeness of sensitive upland and wetland Vegetation Communities within the particular Area Plan;
  • maintenance of habitat contiguity;
  • maintenance of large habitat blocks;
  • maintenance of ridgelines and riparian areas for movement of mammals such as bobcats or mountain lions as appropriate;
  • minimization of Edge Effects;
  • consideration of "directional" influences such as migration/dispersal patterns, rain, wind, fire;
  • consideration of patch sizes and dispersal patches for Planning Species as appropriate.

For each Area Plan, a Conceptual Reserve Design was roughly sketched onto a vegetation map with Planning Species occurrence data and Biological Issues and Considerations highlighted. The concept was refined based on constraints and opportunities as represented on existing and planning land use maps, aerial photographs, topography maps, parcel maps, existing land ownership maps and edge area maps. Consideration was given to adjacent Area Plans to provide for appropriate edge matching and appropriate connectivity across planning and jurisdictional boundaries. The Conceptual Reserve Design developed during this process was used primarily for the purposes of drafting Area Plan Criteria, developing target acreage ranges for Area Plan Subunits, and developing quantitative data for the MSHCP species analyses. The conceptual designs for each Area Plan do not represent the only possible MSHCP Conservation Area that may be assembled within a particular Area Plan during the long-term MSHCP implementation process. Flexibility is incorporated in the target acreage ranges and the Area Plan Criteria to allow Reserve Assembly to be informed by project-specific data and planning as part of the MSHCP implementation process. In addition, a Criteria Refinement Process is incorporated in the MSHCP as discussed in Section 6.5 of this document.

The following specific map resources were used in development of the Conceptual Reserve Design for each Area Plan:

  • vegetation map (1"= 3,000' scale)
  • map of Planning Species occurrences (1" = 3,000' scale)
  • coastal sage scrub habitat quality map (1" = 3,000' scale)
  • November 2000 DOQQs (infrared)
  • soils map (Knecht 1971)
  • edge area map (DUDEK 2000)
  • Bioregions map (DUDEK 2000)
  • topography map (USGS 7.5 minute quads)
  • parcel map (1" = 3,000' scale acetate overlay)
  • existing land ownership/land status map (1" = 3,000' scale acetate overlay)
  • MSHCP Alternative 1 schematic (1" = 3,000' scale acetate overlay)
  • General Plan Alternative 3 for planned land uses (1" = 3,000' scale acetate overlay)
  • open space, trails and critical circulation study map
  • site-specific mapping information with varying levels of detail and precision obtained from a variety of sources.

USGS quarter sections (i.e., approximate 160-acre Cells) were then overlain on the Conceptual Reserve Design such that each Cell is an area in real space with a legal description but without being tied to a specific County assessor's legal parcel. Cells were then either aggregated into a Cell Group or retained as individual Cells depending upon the level of Conservation and configuration of the particular Cell or Cell Group. Cells with conservation goals anticipated to be less than 5% were either eliminated or aggregated into a Cell Group. Cells with conservation goals anticipated to be greater than 90% were aggregated into a Cell Group. Cells and Cell Groups were then aggregated into Area Plan Subunits and each Area Plan Subunit was named and numbered. Variable target acreage ranges, Planning Species and Biological Issues and Considerations were identified for each Area Plan Subunit. The variable target acreage ranges were generally based on the difference between the area of the Criteria Area for the particular Subunit and the area of the Conceptual Reserve Design for the particular Subunit. Figure 3-3 and Table 3-2 depict the locations of the Area Plan Subunits and provide a summary of the target acreage ranges for each Subunit. The names of the Subunits, and Planning Species and Biological Issues and Considerations for each Subunit are presented in the individual Area Plan texts in Sections 3.3.2 through 3.3.17 of this document.

Each Cell was assigned a quadrat cell identification number and each Cell Group was assigned a letter code. For each Cell or Cell Group, Criteria were drafted to provide an explicit description of the areas to be conserved and Criteria were recorded on a matrix for each Area Plan. The individual Area Plan matrices are included with the Area Plan texts in Sections 3.3.2 through 3.3.17 of this document. The Criteria for each Cell or Cell Group provide: (1) a statement of the Core and Linkage features within the particular Cell or Cell Group toward which Reserve Assembly will be directed; (2) a statement of the focus of Conservation within the particular Cell or Cell Group; (3) a statement of the reserve configuration or connectivity focus for the particular Cell or Cell Group; and (4) a statement of the geographic location and percentage of Conservation desired within the particular Cell or Cell Group. For example, the Criteria for a particular Cell might be: "Conservation within this Cell will contribute to assembly of Proposed Core 6. Conservation within this Cell will focus on coastal sage scrub and chaparral. Conservation within this Cell will be connected to proposed Conservation within Cell 1234 to the west. Conservation within this Cell will occur in the northern 30%-40% of the Cell." It should be noted that the Criteria statements for Cells and Cell Groups are intended to be considered as a whole to guide Reserve Assembly; individual Criteria statements are not intended to be used as stand-alone guidance for Reserve Assembly. The Criteria are written with the intent that a "non-technical observer" could re-create the initial MSHCP Conservation Area concept for the particular Cell or Cell Group. In the Criteria matrices for the individual Area Plans, Cell Groups are listed first in letter order (A, B, C, D, etc.) with individual Cells in a Cell Group listed in numerical order, followed by individual Cells (not in a Cell Group) listed in numerical order.

Results

The Area Plan texts in the following Sections 3.3.2 through 3.3.17 present the Results of the application of the Methodology described above. Implementation of the Reserve Assembly guidance incorporated in the MSHCP including the guidance provided in the descriptions of the MSHCP Conservation Area, the Cores and Linkages, the Area Plan Subunit Biological Issues and Considerations and Planning Species, and the Cell and Cell Group Criteria are intended to result in a MSHCP Conservation Area configuration that provides significant blocks of Habitat, minimizes internal fragmentation and Edge Effects, and maximizes the ratio of surface area to perimeter.

Criteria Review Consistency Process

Application of the Reserve Assembly guidance provided in the MSHCP is intended to occur sequentially, beginning at the broad, landscape scale and proceeding through the individual Cell Criteria. This sequential approach is important to achieve the desired outcome, which, as noted above, is a reserve configuration that provides significant blocks of Habitat and minimizes internal fragmentation. When individual projects are considered, Permittee staff and applicants should first examine the project in the context of the overall MSHCP Conservation Area by relating the project to the MSHCP Conservation Area description in Section 3.2.2 of the Plan and the descriptions of the applicable Cores and Linkages in Section 3.2.3 of the Plan. The descriptions of the Cores and Linkages include factors such as variable target acreages and perimeter to area ratios, as well as species, configuration and management issues, and all of those factors should be reviewed to provide a context for the review of the particular individual project. Staff and applicants can then have a common understanding of the reserve configuration requirements of the MSHCP in the general project area. After such an understanding of the context, staff and applicants should look at the particular individual project more specifically to examine how it might contribute to, or conflict with, assembly of the MSHCP Conservation Area consistent with reserve configuration requirements.

The sequential process should continue with identification of the specific Area Plan and Area Plan Subunit within which the particular individual project is located. Planning Species and Biological Issues and Considerations as well as variable target acreages for the overall Area Plan and Area Plan Subunit should be reviewed between Permittee staff and the applicant along with any available project specific biological information. Planning Species and Biological Issues and Considerations that apply to the specific project should be identified. Not all Planning Species and Biological Issues and Considerations for a particular Area Plan or Area Plan Subunit will apply to every project.

The process should continue with a review of the specific Criteria for the identified Cell or Cell Group within which the project site is located. The first criterion for each Cell or Cell Group is the identification of the applicable Core or Linkage. This relationship of the project to the applicable Core or Linkage should already have been identified and discussed as part of the first steps in the sequential process. The next criteria for each Cell or Cell Group are the identification of Vegetation Communities toward which Conservation should be directed along with connectivity requirements. These criteria should be considered for each individual project based on the context established through the earlier review of Cores and Linkage and the overall MSHCP Conservation Area description. Finally, the project should be examined with respect to the percentage conservation portion of the Cell Criteria, which is the last criterion provided for each Cell and Cell Group. While achieving the precise percentage conservation criterion for each Cell or Cell Group would ultimately result in assembly of 153,000 acres of Additional Reserve Lands as envisioned in the MSHCP, it should be noted that achievement of the variable target acreages will be measured on a Core and Linkage or Area Plan and Area Plan Subunit basis, not on an individual project or Cell/Cell Group basis. As noted in the discussion of Reserve Assembly Accounting in Section 6.7, adjustments are anticipated during the long-term MSHCP implementation process to respond to new information and baseline changes.

Implementation of this sequential review process will require active and informed participation on the part of Permittee staff and project applicants. Training of Permittee staff will occur within the first year of MSHCP implementation and will be ongoing during the life of the Permit.

It will be necessary to document the process described above in the form of findings that the proposed project has been determined to be consistent with the requirements of the MSHCP. An approach and format for these findings is provided below.

Implementation and Findings documenting the process described above will be made by the Local Permittees for each project for which a Criteria consistency review is conducted and will be included in the appropriate project review and approval documentation. The information and Findings will include the following:

  1. Brief description of project and location focusing on location of the project with respect to applicable MSHCP Core or Linkage, Area Plan Subunit and Cell or Cell Group;
  2. Brief description of onsite biological resources focusing on presence or absence of Planning Species identified for the applicable Core or Linkage and Area Plan Subunit, Biological Issues and Considerations identified for the applicable Area Plan Subunit, and focus Vegetation Communities and connectivity identified for the applicable Cell or Cell Group;
  3. Brief analysis of the relationship of the project as proposed to the biological resources issues noted in (b) and discussion of the proposed project contribution toward achieving the MSHCP Criteria;
  4. Brief discussion of any conflicts with the MSHCP Criteria due to project design features, surrounding land use conditions, on?site conditions different from those anticipated in the MSHCP or other appropriate factors and summary of features incorporated in the project to address those conflicts;
  5. Statement of Findings that the proposed project has been determined to be consistent with the MSHCP Criteria and the rationale for this determination. The Findings shall incorporate the information generated as part of (a) through (d) above and shall specifically describe the consistency of the project with Reserve Assembly criteria with emphasis on reserve configuration and connectivity and covered species.

Equivalent or biologically superior findings made in accordance with the processes described in Sections 6.1.2, 6.1.3, 6.3.2 and 6.5 of this document may be combined with these Criteria review consistency findings. When project consistency findings have been made and accepted by the Local Permittees, the Reserve Assembly Criteria in Sections 3.3.2 through 3.3.17 of the Plan will no longer apply to the project site for which such consistency findings have been made.

Once consistency findings are made for a project, subsequent permits for the same project are only subject to substantial conformance review when subsequent permits are issued. For example, if consistency findings are made at the specific plan level, review at the tentative map level would be limited to review for substantial conformance with the initial consistency findings. Likewise, it is understood that review of a site for consistency with the MSHCP Criteria is properly made when the site is initially converted from vacant to developed land. Redevelopment of a site from one urban use to another would not be subject to MSHCP Criteria except with respect to the potential net change in the requirements. For example, if four houses are demolished and six houses are proposed at the same location, only the additional two houses will be subject to the MSHCP requirements. Likewise, if a slaughterhouse is initially reviewed and determined to be consistent with the MSHCP Criteria, later conversion of this use to another developed use would not trigger MSHCP requirements with the exception of requirements associated with payment of fees.

Criteria Review Consistency Prior to MSHCP Adoption

During the conservation planning process for the MSHCP, a number of projects have proceeded through the entitlement process or have been the subject of a Memorandum of Understanding (MOU) and have sometimes been modified to be consistent with the MSHCP Core and Linkage guidelines, Area Plan Subunit Biological Issues and Considerations and Cell Criteria. Several of these projects have received local and/or state or federal approvals, but have not yet commenced construction. Future construction of these projects in accordance with the relevant approvals would be considered to be consistent with the MSHCP guidelines and Criteria. Projects known to fall within this category are listed below.

* Note: The MSHCP Conservation Area lands contributed by the projects listed above were negotiated in the course of Interim Project Review (IPR). IPR used the available MSHCP information at the time and recognized that the information that gave rise to the Cells noted above and in the MSHCP was still in an iterative state of refinement. In many instances, the Cells did not exist at the time of project negotiations.

There are other projects that, while having used the recommendations of the IPR in their respective project designs and ultimate MSHCP contributions, are still being processed through the land use entitlement process and have not yet received final legislative approval. These projects are being evaluated against the best available MSHCP maps and information and conservation acreages have been proposed and/or determined with the project applicants.

3.3.7 Lake Mathews/Woodcrest Area Plan

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for the Lake Mathews/Woodcrest Area Plan. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for the Lake Mathews/Woodcrest Area Plan is 16,695 - 18,950 acres; it is composed of approximately 13,480 acres of existing Public/Quasi-Public Lands and 3,215 - 5,470 acres of Additional Reserve Lands.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here as "Cores and Linkages"). The Cores and Linkages listed below are within the Lake Mathews/Woodcrest Area Plan. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within the Lake Mathews/Woodcrest Area Plan, see Section 3.2.3 and MSHCP Volume II, Section A.

Cores and Linkages within Lake Mathews/Woodcrest Area Plan

  • Contains a small portion of Proposed Core 1
  • Contains a portion of Proposed Extension of Existing Core 2
  • Contains a portion of Proposed Linkage 3

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the Lake Mathews/Woodcrest Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the Lake Mathews/Woodcrest Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Lake Mathews/Woodcrest Area Plan is divided into four Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit.

  • Contains western two-thirds of Proposed Noncontiguous Habitat Block 5
  • Contains a portion of Existing Core H

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the Lakeview/Nuevo Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the Lakeview/Nuevo Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Lakeview/Nuevo Area Plan is divided into two Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit. For more information regarding specific conservation objectives for the Planning Species, see Section 9.0. Subunit boundaries are depicted on the Cells and Cell Groupings map displays (Figures 3-16 and 3-17). Table 3-9 presents the Criteria for the Lakeview/Nuevo Area Plan.

thread-leaved brodiaea 24 acres
spreading navarretia 5 acres
Davidson's saltscale and Wright's trichochoronis (aggregate) 0.2 acre
Coulter's goldfields 33 acres

Survey Methodology: Prior to beginning the survey effort, a map of known target species occurrences will be obtained from RCFCWCD and known localities will be visited to establish the phenology of the target Covered Species. All new occurrences of target Covered Speices will be mapped and recorded on a global positioning system (GPS).

Site specific information, such as number of individuals present (direct count or estimate from sub samples), other species present, site conditions, and types and levels of disturbance as appropriate will be recorded for each occurrence polygon.

Mapping of target Covered Species will be done on topographic map or aerial photograph not smaller than 400-scale. If an aerial photograph is used, it will not be more than two years old. A minimum of four GPS points will be taken, one each at the north, south, east and west limits of the polygon. Where polygons are large or exhibit irregular shapes, enough GPS points will be taken to accurately record the limits of occupied area. Where there are gaps or breaks between individuals of the target Covered Species of 10 meters or more, those individuals will be mapped and recorded via GPS into separate polygons.

Voucher specimens will be obtained from new occurrences more than one quarter section away from known occurrences of the same species. Collections should not be excessive. No material will be collected from known occurrences, unless species identification is in doubt. Vouchers are to be deposited at a recognized herbarium with the recorded GPS location information recorded on the specimen label.

Maps, recorded GPS information and disposition of any voucher specimens are to be turned over to the official MSHCP data repository and RCFCWCD for digitizing. Records not turned over for digitizing and vouchered as appropriate cannot be counted for purposes of meeting the acreage requirements noted above. Occurrences digitized by RCFCWCD or the MSHCP data repository and vouchered as appropriate can be counted towards the acreage requirements noted above as long as those occurrences are not subject to: (1) grazing of domestic livestock; (2) ground disturbing activities, including farming and weed suppression; (3) dewatering or irrigation; and (4) application of soil amendments (including manure and sludge). Occurrences documented subsequent to any of those disturbances can be counted for purposes of meeting the acreage requirements noted above until such time as the new occurrence is disturbed. Surveyors are to record the location and extent of the above listed disturbances in the field as they are encountered. Disturbance information is to be provided to RCFCWCD for digitization with the plant locality data.

3.3.9 Mead Valley Area Plan

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for the Mead Valley Area Plan. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for the Mead Valley Area Plan is 4,980 to 6,730 acres; it is composed of approximately 3,095 acres of existing Public/Quasi-Public Lands and 1,885 - 3,635 acres of Additional Reserve Lands. The City of Perris is located entirely within the Mead Valley Area Plan. The target acreage range within the City of Perris is 720 - 1,400 acres. The City of Perris target acreage is included within the 1,885 - 3,635 acre target conservation range on Additional Reserve Lands for the entire Mead Valley Area Plan.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as "Cores and Linkages"). The Cores and Linkages listed below are within the Mead Valley Area Plan. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within the Mead Valley Area Plan, see Section 3.2.3, and MSHCP Volume II, Section A.

Cores and Linkages within Mead Valley Area Plan

  • Contains a portion of Proposed Constrained Linkage 19
  • Contains a portion of Proposed Core 1
  • Contains a portion of Proposed Extension of Existing Core 4
  • Contains a small portion of Proposed Linkage 3
  • Contains a portion of Proposed Linkage 7
  • Contains a portion of Proposed Noncontiguous Habitat Block 4

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the Mead Valley Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the Mead Valley Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Mead Valley Area Plan is divided into four Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit. For more information regarding specific conservation objectives for the Planning Species, see Section 9.0. Subunit boundaries are depicted on the Cells and Cell Groupings map displays (Figures 3-18 and 3-19). Table 3-10 presents the Criteria for the Mead Valley Area Plan.

Subunit 1: Motte-Rimrock

Target acreage range for Additional Reserve Lands within Subunit: 315-590 acres

Cell Groups within this Subunit: A and B

Biological Issues and Considerations:

The Target acreage range for Additional Reserve Lands within this Subunit incoprorates the following acreage goals for individual plant populations within this Subunit. The acreage goals for individual plant populations noted below are intended to be accomplished within this Subunit in combination with Subunit 1 of the Lakeview/Nuevo Area Plan.

San Jacinto Valley crownscale 236 acres
thread-leaved brodiaea 24 acres
spreading navarretia 5 acres
Davidson's saltscale and Wright's trichochoronis (aggregate) 0.2 acre
Coulter's goldfields 33 acres

Survey Methodology: Prior to beginning the survey effort, a map of known target species occurrences will be obtained from RCFCWCD and known localities will be visited to establish the phenology of the target Covered Species. All new occurrences of target Covered Speices will be mapped and recorded on a global positioning system (GPS).

Site specific information, such as number of individuals present (direct count or estimate from sub samples), other species present, site conditions, and types and levels of disturbance as appropriate will be recorded for each occurrence polygon.

Mapping of target Covered Species will be done on topographic map or aerial photograph not smaller than 400-scale. If an aerial photograph is used, it will not be more than two years old. A minimum of four GPS points will be taken, one each at the north, south, east and west limits of the polygon. Where polygons are large or exhibit irregular shapes, enough GPS points will be taken to accurately record the limits of occupied area. Where there are gaps or breaks between individuals of the target Covered Species of 10 meters or more, those individuals will be mapped and recorded via GPS into separate polygons.

Voucher specimens will be obtained from new occurrences more than one quarter section away from known occurrences of the same species. Collections should not be excessive. No material will be collected from known occurrences, unless species identification is in doubt. Vouchers are to be deposited at a recognized herbarium with the recorded GPS location information recorded on the specimen label.

Maps, recorded GPS information and disposition of any voucher specimens are to be turned over to the official MSHCP data repository and RCFCWCD for digitizing. Records not turned over for digitizing and vouchered as appropriate cannot be counted for purposes of meeting the acreage requirements noted above. Occurrences digitized by RCFCWCD or the MSHCP data repository and vouchered as appropriate can be counted towards the acreage requirements noted above as long as those occurrences are not subject to: (1) grazing of domestic livestock; (2) ground disturbing activities, including farming and weed suppression; (3) dewatering or irrigation; and (4) application of soil amendments (including manure and sludge). Occurrences documented subsequent to any of those disturbances can be counted for purposes of meeting the acreage requirements noted above until such time as the new occurrence is disturbed. Surveyors are to record the location and extent of the above listed disturbances in the field as they are encountered. Disturbance information is to be provided to RCFCWCD for digitization with the plant locality data.

3.3.10 The Pass Area Plan

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for The Pass Area Plan. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for The Pass Area Plan is 22,510 - 27,895 acres; it is composed of approximately 13,970 acres of existing Public/Quasi-Public Lands and 8,540 - 13,925 acres of Additional Reserve Lands. The City of Banning, City of Beaumont, and City of Calimesa sit entirely within The Pass Area Plan. The target acreage range within the City of Banning is 50 - 90 acres. The target acreage range within the City of Beaumont is 5,440 - 9,060 acres. The target acreage range within the City of Calimesa is 1,240 - 2,240 acres. The target acreages of the three Cities are included within the 8,540 - 13,925 acre target conservation range on Additional Reserve Lands for the entire The Pass Area Plan.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as "Cores and Linkages"). The Cores and Linkages listed below are within The Pass Area Plan. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within The Pass Area Plan, see Section 3.2.3, and MSHCP Volume II, Section A.

Cores and Linkages within the Pass Area Plan

  • Contains the Proposed Constrained Linkage 22
  • Contains the Proposed Constrained Linkage 23
  • Contains a portion of Proposed Core 3
  • Contains a portion of Proposed Linkage 6
  • Contains Proposed Linkage 12
  • Contains a portion of Existing Core I
  • Contains a portion of Existing Core K
  • Contains a portion of Existing Noncontiguous Habitat Block B

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within The Pass Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within The Pass Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Pass Area Plan is divided into three Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit. For more information regarding specific conservation objectives for the Planning Species, see Section 9.0. Subunit boundaries are depicted on the Cells and Cell Groupings map displays (Figures 3-20 and 3-21). Table 3-11 presents the Criteria for The Pass Area Plan.

Special Linkage Area: This Special Linkage Area will contribute to assembly of a portion of the San Gorgonio River/San Bernardino-San Jacinto Mountains Linkage. Tribal coordination regarding American Indian Lands will be necessary in this area. The San Gorgonio River/San Bernardino-San Jacinto Mountains Linkage includes locations within and outside the MSHCP Plan Area. Features of the entire linkage area are described in Missing Linkages: Restoring Connectivity to the California Landscape (Penrod, K., November 2, 2000). A copy of this report is attached as Exhibit 24 to Comment Letter D in Volume V of the MSHCP. Local Permittees will apply the following rebuttable presumption of significance, taken from Appendix G to the 1998 State CEQA Guidelines, in CEQA review of proposed public and private projects within this Special Linkage Area and apply mitigation measures as appropriate: "Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?" Draft and Final CEQA documentation prepared by Local Permittees for projects within this Special Linkage Area will be forwarded to the RCA for informational purposes to provide for MSHCP coordination regarding this area.

Special Linkage Area: This Special Linkage Area will contribute to assembly of a portion of the San Gorgonio River/San Bernardino-San Jacinto Mountains Linkage. Tribal coordination regarding American Indian Lands will be necessary in this area. The San Gorgonio River/San Bernardino-San Jacinto Mountains Linkage includes locations within and outside the MSHCP Plan Area. Features of the entire linkage area are described in Missing Linkages: Restoring Connectivity to the California Landscape (Penrod, K., November 2, 2000). A copy of this report is attached as Exhibit 24 to Comment Letter D in Volume V of the MSHCP. Local Permittees will apply the following rebuttable presumption of significance, taken from Appendix G to the 1998 State CEQA Guidelines, in CEQA review of proposed public and private projects within this Special Linkage Area and apply mitigation measures as appropriate: "Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?" Draft and Final CEQA documentation prepared by Local Permittees for projects within this Special Linkage Area will be forwarded to the RCA for informational purposes to provide for MSHCP coordination regarding this area.

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as "Cores and Linkages"). The Cores and Linkages listed below are within the Reche Canyon/Badlands Area Plan. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within the Reche Canyon/Badlands Area Plan, see Section 3.2.3 and MSHCP Volume II, Section A.

Cores and Linkages within the Reche Canyon/Badlands Area Plan

  • Contains all of Proposed Constrained Linkage 8
  • Contains a large portion of Proposed Core 3
  • Contains a large portion of Proposed Linkage 4
  • Contains a small portion of Existing Core H

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the Reche Canyon/Badlands Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the Reche Canyon/Badlands Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Reche Canyon/Badlands Area Plan is divided into four Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit.

3.3.12 REMAP Area Plan

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for the REMAP Area Plan. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for the REMAP Area Plan is 192,315 – 209,385 acres; it is composed of approximately 150,915 acres of existing Public/Quasi-Public Lands and 41,400 – 58,470 acres of Additional Reserve Lands.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as “Cores and Linkages"). The Cores and Linkages listed below are within the REMAP Area Plan. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within the REMAP Area Plan, see Section 3.2.3, and MSHCP Volume II, Section A.

Cores and Linkages within REMAP Area Plan

  • Contains a portion of Proposed Core 4
  • Contains a portion of Proposed Core 5
  • Contains all of Proposed Core 6
  • Contains a large portion of Proposed Core 7
  • Contains a small portion of Proposed Linkage 11
  • Contains a portion of Proposed Linkage 13
  • Contains a portion of Proposed Linkage 14
  • Contains all of Proposed Linkage 15
  • Contains all of Proposed Linkage 16

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the REMAP Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the REMAP Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The REMAP Area Plan is divided into seven Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit. For more information regarding specific conservation objectives for the Planning Species, see Section 9.0.

3.3.13 San Jacinto Valley Area Plan

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for the San Jacinto Valley Area Plan. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for the San Jacinto Valley Area Plan is 21,740 – 29,665 acres; it is composed of approximately 10,200 acres of existing Public/Quasi-Public Lands and 11,540 – 19,465 acres of Additional Reserve Lands. The City of Hemet and the City of San Jacinto sit entirely within the San Jacinto Valley Area Plan. The target acreage range within the City of Hemet is 620– 1,000 acres. The target acreage range within the City of San Jacinto Valley is 1,580– 2,680 acres. The target acreages of both Cities are included within the 11,540 – 19,465 acre target conservation range on Additional Reserve Lands for the entire San Jacinto Valley Area Plan.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as “Cores and Linkages"). The Cores and Linkages listed below are within the San Jacinto Valley Area Plan. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within the San Jacinto Valley Area Plan, see Section 3.2.3 and MSHCP Volume II, Section A.

Cores and Linkages within the San Jacinto Valley Area Plan

  • Contains a portion of Proposed Constrained Linkage 20
  • Contains all of Proposed Constrained Linkage 21
  • Contains a portion of Proposed Core 3
  • Contains a portion of Proposed Core 4
  • Contains most of Proposed Core 5
  • Contains most of Proposed Linkage 11
  • Contains a large portion of Proposed Linkage 14
  • Contains eastern portion of Proposed Noncontiguous Habitat Block 5
  • Contains all of Proposed Noncontiguous Habitat Block 6
  • Contains a large portion of Proposed Noncontiguous Habitat Block 7
  • Contains a small portion of Existing Constrained Linkage C
  • Contains a small portion of Existing Core J

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the San Jacinto Valley Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the San Jacinto Valley Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The San Jacinto Valley Area Plan is divided into five Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit.

Special Linkage Area: This Special Linkage Area will contribute to assembly of a portion of the Santa Ana-Palomar Mountains Linkage for the benefit of Covered Species. Tribal coordination regarding American Indian Lands will be necessary in this area. The Santa Ana-Palomar Mountains Linkage includes locations within and outside the MSHCP Plan Area. Features of the entire linkage area are described in the Santa Ana-Palomar Mountains Linkage Conservation Design Plan Working Draft (SDSU Field Station Programs and South Coast Wildlands Project, February 2003). A working draft of the Conservation Design Plan is attached to Comment Letter X3 in Volume V, of the MSHCP. Local Permittees will apply the following rebuttable presumption of significance, taken from Appendix G to the 1998 State CEQA Guidelines, in CEQA review of proposed public and private projects within this Special Linkage Area and apply mitigation measures as appropriate: "Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?" Draft and Final CEQA documentation prepared by Local Permittees for projects within this Special Linkage Area will be forwarded to the RCA for informational purposes to provide for MSHCP coordination regarding this area.

Special Linkage Area: This Special Linkage Area will contribute to assembly of a portion of the Santa Ana-Palomar Mountains Linkage for the benefit of Covered Species. Tribal coordination regarding American Indian Lands will be necessary in this area. The Santa Ana-Palomar Mountains Linkage includes locations within and outside the MSHCP Plan Area. Features of the entire linkage area are described in the Santa Ana-Palomar Mountains Linkage Conservation Design Plan Working Draft (SDSU Field Station Programs and South Coast Wildlands Project, February 2003). A working draft of the Conservation Design Plan is attached to Comment Letter X3 in Volume V, of the MSHCP. Local Permittees will apply the following rebuttable presumption of significance, taken from Appendix G to the 1998 State CEQA Guidelines, in CEQA review of proposed public and private projects within this Special Linkage Area and apply mitigation measures as appropriate: "Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?" Draft and Final CEQA documentation prepared by Local Permittees for projects within this Special Linkage Area will be forwarded to the RCA for informational purposes to provide for MSHCP coordination regarding this area.

 

 

 

 

 

 

 

 


 

 

 

3.3.16 Temescal Canyon Area Plan

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for the Temescal Canyon Area Plan. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for the Temescal Canyon Area Plan is 29,555 – 31,870 acres; it is composed of approximately 26,070 acres of existing Public/Quasi-Public Lands and 3,485 – 5,800 acres of Additional Reserve Lands. The City of Corona sits entirely within the Temescal Area Plan. The target acreage range within the City of Corona is 330 – 610 acres. The City of Corona target acreage is included within the 3,485 – 5,800 acre target conservation range on Additional Reserve Lands for the entire Temescal Area Plan.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as “Cores and Linkages.)

Cores and Linkages within the Temescal Canyon Area Plan

  • Contains Proposed Constrained Linkage 1
  • Contains Proposed Constrained Linkage 2
  • Contains a large portion of Proposed Constrained Linkage 3
  • Contains a large portion of Proposed Constrained Linkage 4
  • Contains a large portion of Proposed Extension of Existing Core 1
  • Contains a large portion of Proposed Extension of Existing Core 2
  • Contains a small portion of Existing Core A

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the Temescal Canyon Area Plan are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the Temescal Canyon Area Plan. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Temescal Canyon Area Plan is divided into five Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit. For more information regarding specific conservation objectives for the Planning Species, see Section 9.0. Subunit boundaries are depicted on the Cells and Cell Groupings map displays (Figures 3-32 and 3-33). Table 3-17 presents the Criteria for the Temescal Canyon Area Plan.

3.3.17. Cities of Riverside/Norco

This section identifies target acreages, applicable Cores and Linkages, Area Plan Subunits and Criteria for the Cities of Riverside/Norco. For a summary of the methodology and map resources used to develop the target acreages and Criteria for the MSHCP Conservation Area, including this Area Plan, see Section 3.3.1.

Target Acreages

The target conservation acreage range for the Cities of Riverside/Norco is 3,465 – 3,615 acres; it is composed of approximately 3,375 acres of existing Public/Quasi-Public Lands and 90 – 240 acres of Additional Reserve Lands. The City of Norco and City of Riverside sit entirely within the Cities of Riverside/Norco. The target acreage range within the City of Norco is 60 – 140 acres. The target acreage range within the City of Riverside is 55 – 125 acres. The target acreages of both Cities are included within the 90 – 240 acre target conservation range on Additional Reserve Lands for the entire Cities of Riverside/Norco.

Applicable Cores and Linkages

The MSHCP Conservation Area comprises a variety of existing and proposed Cores, Linkages, Constrained Linkages and Noncontiguous Habitat Blocks (referred to here generally as “Cores and Linkages"). The Cores and Linkages listed below are within the Cities of Riverside/Norco. For descriptions of these Cores and Linkages and more information about the biologically meaningful elements of the MSHCP Conservation Area within the Cities of Riverside/Norco, see Section 3.2.3 and MSHCP Volume II, Section A.

Cores and Linkages within the Cities of Riverside/Norco

  • Contains a small portion of Proposed Constrained Linkage 7
  • Contains a small portion of Existing Core A

Descriptions of Planning Species, Biological Issues and Considerations and Criteria for each Area Plan Subunit within the Cities of Riverside/Norco are presented later in this section. These descriptions, combined with the descriptions of the Cores and Linkages referred to above, provide information about biological issues to be considered in conjunction with Reserve Assembly within the Cities of Riverside/Norco. As noted in Section 3.1, the Area Plan boundaries established as part of the Riverside County General Plan were selected to provide an organizational framework for the Area Plan Subunits and Criteria. While these boundaries are not biologically based, unlike the Cores and Linkages, they relate specifically to General Plan boundaries and the jurisdictional boundaries of incorporated Cities and were selected to facilitate implementation of the MSHCP in the context of existing institutional and planning boundaries.

Area Plan Subunits

The Cities of Riverside/Norco is divided into two Subunits. For each Subunit, target conservation acreages are established along with a description of the Planning Species, Biological Issues and Considerations, and Criteria for each Subunit. For more information regarding specific conservation objectives for the Planning Species, see Section 9.0.

3.4 ALTERNATIVES CONSERVATION STRATEGIES CONSIDERED IN THE CONSERVATION PLANNING PROCESS

A variety of alternatives were considered as part of the conservation planning process. The range of alternatives was defined by the MSHCP Advisory Committee and relates to the rough conservation locations, acreage estimates and species lists developed for the August 9, 1999 "Draft MSHCP Proposal," as reviewed by the Wildlife Agencies. The Alternatives definition was data driven and based on biological, land use, economic and regulatory consideration as well as the overall MSHCP planning principles described in Section 1.0 of this document.

In addition to the alternatives identified by the stakeholders and described in detail below, a Description of Preliminary Alternatives was assembled and distributed to stakeholders in February 2000. Those alternatives were based on General Plan land use alternatives being developed as part of the RCIP General Plan Update. Those alternatives influenced the alternatives development process; however, it was decided to develop General Plan land use and MSHCP alternatives separately as part of the RCIP process, and the Preliminary Alternatives presented in the February 2000 document were not developed further.

3.4.1 Listed, Proposed and Strong Candidate Species Alternative

This alternative was developed at the request of the MSHCP Advisory Committee to depict a potential conservation scenario that would address listed, proposed and strong candidate species. A total of 32 listed and proposed species occur in the MSHCP Plan Area including the following: Swainson's hawk, mountain plover, western yellow-billed cuckoo, southwestern willow flycatcher, peregrine falcon, bald eagle, coastal California gnatcatcher, least Bell's vireo, San Bernardino kangaroo rat, Stephens' kangaroo rat, arroyo toad, California red-legged frog, mountain yellow-legged frog, southern rubber boa, Quino checkerspot butterfly, Delhi Sands flower- loving fly, Riverside fairy shrimp, vernal pool fairy shrimp, Santa Ana sucker, Mohave tarplant, Munz's onion, Parish's meadowfoam, San Diego ambrosia, San Jacinto Valley crownscale, Nevin's barberry, thread-leaved brodiaea, Vail Lake ceanothus, slender-horned spine flower, Santa Ana River woollystar, San Diego button-celery, spreading navarretia, and California Orcutt grass. In addition to the listed and proposed species, this alternative also considers conservation needs for the following seven species identified as “strong candidates" in discussions with the MSHCP Advisory Committee: tricolored blackbird (breeding colony), cactus wren, burrowing owl, western pond turtle, San Bernardino mountain kingsnake, San Diego mountain kingsnake and Los Angeles pocket mouse. The focus of Conservation for this alternative are these 39 listed, proposed and strong candidate species.

It should be noted that this alternative focuses largely on Conservation of the 39 species noted above with less consideration of the draft Planning Agreement language and the broad-based NCCP biological tenets. While large habitat blocks and broad Linkages are incorporated in this alternative in some areas to provide for an MSHCP Conservation Area scenario that would address the conservation needs of the focus species, less emphasis is placed in this alternative on broad-based ecosystem Conservation.

The generalized reserve configuration under this alternative is depicted in Figure 3-36. Table 3-19 provides a summary of acreages potentially conserved under this alternative, by Vegetation Community. These acreages are estimates of areas that are anticipated to be conserved from within the generalized reserve configuration depicted in Figure 3-36. As shown in Table 3-19, under this alternative a total of 465,830 acres would be conserved, including 346,530 acres within existing Public/Quasi-Public Lands and 119,300 acres of Additional Reserve Lands.

New Core Areas in the Badlands, Vail Lake/Wilson Creek/Sage, and Anza Valley areas identified in the August 9 “Draft MSHCP Proposal," were identified in this alternative. Conservation needs for the following species are located in these areas: Badlands - tricolored blackbird, cactus wren, Los Angeles pocket mouse; Vail Lake/Wilson Creek/Sage - Quino checkerspot butterfly, coastal California gnatcatcher, burrowing owl, least Bell's vireo, arroyo toad, cactus wren, Vail Lake ceanothus, Nevin's barberry, slender-horned spine flower; Anza Valley - cactus wren, Stephens' kangaroo rat, Los Angeles pocket mouse, and Quino checkerspot butterfly.

Habitat blocks included in the Conceptual Conservation Scenario but absent from this alternative include La Sierra Hills, Norco Hills and Jurupa Hills. While the La Sierra Hills and Norco Hills areas represent moderately large blocks of intact Habitat and support a variety of species, they do not support substantial populations or meet habitat requirements for the focus species under this alternative, and therefore are not included in this alternative. Likewise, the Jurupa Hills do not support substantial populations of the focus species under this alternative. Scattered coastal California gnatcatcher observations are, however, known from the Jurupa Hills and this area may contribute to coastal California gnatcatcher Conservation outside the MSHCP Plan Area. For this reason, the Jurupa Hills may need to be evaluated in greater detail should this alternative be selected for further study.

A variety of Linkages and Constrained Linkages are included in the Conceptual Conservation Scenario but absent from this alternative including substantial Linkages east of Lake Skinner and Diamond Valley Lake; the upland portions of the Linkage along Temescal Wash north of Alberhill; the Tenaja corridor Linkage; and the Cahuilla Creek Linkage east of the Vail Lake/Wilson Creek/Sage Core Area. Constrained Linkages absent from this alternative include lower Warm Springs and Tucalota Creeks; a variety of optional Linkages along upper Warm Springs Creek and in the French Valley area; Linkages to the Santa Ana River via Springbrook Wash and channelized portions of Temescal Wash; and Linkages in the Cherry Valley, Banning Bench and Banning Idyllwild panoramic highway areas. Although these Linkages would contribute to the overall Conceptual Conservation Scenario, they do not provide substantial support for the focus species under this alternative and so are not depicted under this alternative scenario. The channelized portion of Temescal Creek may support breeding for the Santa Ana sucker and this area would need to be considered for inclusion in the MSHCP Conservation Area under this alternative.

3.4.2 Listed and Proposed Species Alternative

This alternative was developed at the request of the MSHCP Advisory Committee to depict a potential conservation scenario that would address only listed and proposed species. A total of 32 listed and proposed species occur in the MSHCP Plan Area as listed in the description for the Listed, Proposed and Strong Candidates alternative. It should be noted that this alternative focuses largely on the Conservation of the 32 listed and proposed species within the MSHCP Plan Area, with less consideration of the broad-based NCCP biological tenets. While large habitat blocks and broad Linkages are incorporated in this alternative in some areas to provide for a conservation scenario that would address the conservation needs of the listed and proposed species, less emphasis is placed in this alternative on broad-based ecosystem Conservation.

The generalized reserve configuration under this alternative is depicted in Figure 3-37. Table 3-20 provides a summary of acreages potentially conserved under this alternative, by Vegetation Community. These acreages are estimates of areas that are anticipated to be conserved from within the generalized reserve configuration depicted in Figure 3-37. As shown in Table 3-20, under this alternative a total of 439,140 acres would be conserved, including 346,530 acres within existing Public/Quasi-Public Lands and 92,610 acres of Additional Reserve Lands.

New Core Areas in the Vail Lake/WilsonCreek/Sage and Anza Valley areas identified in the August 9, 1999 “Draft MSHCP Proposal" were identified in this alternative. Conservation needs for the following species are located in these areas: Vail Lake/Wilson Creek/Sage - Quino checkerspot butterfly, coastal California gnatcatcher, least Bell's vireo, arroyo toad; Vail Lake ceanothus, Nevin's barberry; slender-horned spine flower; Anza Valley - Stephens' kangaroo rat, Quino checkerspot butterfly.

Conservation of the Potrero portion of the Badlands is also anticipated under this alternative. Conservation in this area is focused on Stephens' kangaroo rat and least Bell's vireo.

Habitat blocks included in the Conceptual Conservation Scenario but absent from this alternative include Double Butte and the Lakeview Mountains. While they represent large blocks of intact Habitat and support a variety of species, they do not support substantial populations or meet habitat requirements for the focus species under this alternative and therefore are not included in this alternative. Conservation in the Jurupa Mountains is not anticipated under this alternative. Scattered coastal California gnatcatcher observations are known from the Jurupa Mountains and this area may contribute to Conservation of the coastal California gnatcatcher outside the MSHCP Plan Area. The coastal California gnatcatcher is a listed species and one of the focus species under this alternative. For this reason, the Jurupa Mountains may need to be evaluated in greater detail should this alternative be selected for further study.

Linkages included in the Conceptual Conservation Scenario but absent from this alternative include the Tule Creek Linkage and the Linkage east of Johnson Ranch and south of Lake Skinner. These Linkages were included in the Conceptual Conservation Scenario for Conservation of Los Angeles pocket mouse and burrowing owl respectively. Since these species are not focus species under this listed and proposed species alternative, they are not included in this alternative.

3.4.3 Existing Reserves

At the request of the MSHCP Advisory Committee, the MSHCP consultant completed a brief analysis of species Conservation that could potentially occur under an alternative that focused on existing reserves only. It should be noted that under this scenario, there would be no MSHCP or associated federal and state Permits authorizing Incidental Take.

The existing reserves only alternative is depicted in Figure 3-38. Table 3-21 summarizes vegetation acreages that would potentially be conserved under this alternative. The level of Conservation within existing reserves would be dependent upon activities within the reserves and resource protection efforts undertaken by the Reserve Managers. Information regarding the size, character and mission of the existing reserves is included in the MSHCP Description of Existing Reserves document (April 2000) previously distributed to the MSHCP Advisory Committee. Under this alternative, it is assumed that no additional Conservation or management would occur within the existing reserves beyond that currently occurring or what might occur in the future with implementation of the USFS Southern California Conservation Strategy.

A brief summary of potential species Conservation under the Existing Reserves alternative is presented in Table 3-22. The information provided in Table 3-22 does provide an indication of species not "protected" under this alternative. As shown in the table, of the 32 listed and proposed species, only two bird species (peregrine falcon and western yellow-billed cuckoo) would be considered to be "protected" under this alternative. One mammal species, Stephens' kangaroo rat, would be conserved based on the existing HCP; however, protection would not be expanded to populations outside the existing HCP area. In addition, two amphibian species, mountain yellow-legged frog and California red-legged frog, and three plant species, San Diego button-celery, Mojave tarplant, and Parish's meadowfoam could be considered to be "protected" based on Conservation on Santa Rosa Plateau and on USFS lands. The remaining 24 listed and proposed species would not be considered to be "protected" under this alternative.

3.4.4 No Project/No MSHCP Alternative

Under the No Project Alternative, subregional Permits pursuant to the following state and federal regulations would not be issued: 1)Section 10(a)(1)(B) under the Federal Endangered Species Act; and 2) Section 2835 of the NCCP Act (California Fish and Game Code). Activities involving Take of state and/or federal listed species would require individual permitting on a project-by-project basis, as is currently the case.

Land use changes and policies that are being contemplated to implement the MSHCP would not occur. However, planning currently being conducted under the RCIP for the General Plan and county-wide circulation element could still be adopted. Implementation of the various elements of those plans resulting in Take of listed species and regulated Habitats; however, would need to be permitted separately under the applicable state and federal processes.

Existing reserves would be retained with existing management strategies under the No Project/No MSHCP Alternative. A summary of existing reserves and associated management activities is provided in Table 3-23.

Impacts resulting from development activities are currently subject to a variety of local state and federal regulatory processes. Under the “No Project"/“No MSHCP" Alternative, these existing processes, and the resulting project modifications and mitigation are anticipated to result in some Conservation of Habitats and species within the Plan Area. Biological resources that are afforded the greatest level of protection under existing regulations and policies are those species that are listed as threatened or endangered, and those species and Habitats associated with wetland systems, as further discussed below.

Table 3-24 provides a summary of species currently provided protection under federal and state Endangered Species regulations, their known locations within the MSHCP Plan Area, and their general Habitats and habitat associations. In addition, species occupying areas subject to existing wetland regulations may be conserved under this alternative. Figure 2-3 in Section 2.0 of this document depicts existing mapped wetland resources within the Plan Area. Actual jurisdictional areas would need to be mapped on a more detailed project-by-project basis to determine the specific areas affected. This information is provided to summarize and depict species and potential wetland locations that would receive some protection under the “No Project/“No MSHCP" Alternative based on application of existing regulations.

Conservation of species and Habitats provided through mitigation and compensation under the existing regulatory framework would likely result in a pattern of Conservation that is fragmented, and managed in a piecemeal fashion. There would not be a coordinated system of Linkages provided to connect conservation areas, and the ability to provide Linkages through project-by-project mitigation may be precluded over time through continued Development.

Although the aforementioned regulations and policies would continue to be applied throughout the Plan Area in the absence of a comprehensive MSHCP, history has demonstrated that application of these regulations and policies would not avoid the decline of species in the Plan Area that has resulted in increased listings of species in recent years. Based on historic trends, it is anticipated that under the “No Project"/“No MSHCP" Alternative, new species would continue to be listed in the future, and regulation of those species and their Habitats would be applied under the current regulatory processes.
