VOLUME II - SECTION B SPECIES ACCOUNTS
INTRODUCTION
This Section presents a detailed, comprehensive analyses of the Covered Species to accompany the MSHCP. This Introduction describes the global goals and objectives that will be implemented within the MSHCP Plan Area to support Conservation of the Covered Species. Also included in this Introduction are maps to facilitate review of the individual species accounts. The information contained in this Section is also summarized in Section 9.0 of the MSHCP Plan, Volume I.
As described in the MSHCP Plan, Volume I, the MSHCP is a Criteria-based plan that describes a MSHCP Conservation Area that will be assembled over time. For purposes of analysis and description, a Conceptual Reserve Design has been developed that envisions one of the ways in which the Additional Reserve Lands could be configured to be consistent with MSHCP objectives. This Conceptual Reserve Design forms the basis for the quantitative analyses that appear in the species accounts in this Section and in the MSHCP Conservation Area Description in Section A of the MSHCP Reference Document, Volume II of the MSHCP Plan. The quantitative information presented in these accounts sets the overall parameters for species Conservation and Reserve Assembly, but should not be regarded as absolutes. Some variation in the quantifications is anticipated as the Additional Reserve Lands are assembled to provide for flexibility in Reserve Assembly and to enable responses to changing conditions on the ground during the long-term Reserve Assembly process. Additionally, the species Conservation levels are preliminary and may be modified based on future data collection efforts.
CONSERVATION STRATEGY
A Conservation Strategy has been developed for each of the Covered Species discussed in this section. The Conservation Strategy for each species consists of four components: (1) a global biological goal, (2) a global biological objective, (3) species-specific biological objectives, and (4) management and monitoring activities (as referenced in global biological objective #11).
Global Biological Goal - The following global biological goal applies to the Conservation of each of the MSHCP Covered Species:
- In the MSHCP Plan Area, conserve Covered Species and their Habitats.
Global Biological Objectives - The following global biological objectives will be implemented for the benefit of the MSHCP Covered Species in order to achieve the global biological goal:
Amphibians:
- The MSHCP Conservation Area will be approximately 500,000 acres in size and will be comprised of approximately 347,000 acres of Public/Quasi-Public Lands and approximately 153,000 acres of Additional Reserve Lands. The MSHCP Conservation Area will incorporate the cores and linkages as well as Habitat distributions generally as presented in the MSHCP Conservation Area Description in Section A, Volume II.
- Upland Habitat quality within the MSHCP Conservation Area will be maintained and managed generally in similar or better condition as at the time lands are conveyed to the MSHCP Conservation Area.

Species-Specific Biological Objectives - Species-specific biological objectives have been established for each of the Covered Species in the MSHCP. Species-specific objectives are presented in each of the individual species accounts contained in this section. In the individual species accounts, each species has been assigned a group designation - Group 1, Group 2 or Group 3. These species groupings, which are based on the group definitions incorporated in the Natural Communities Conservation Planning Act, have been assigned to assist development of individual species objectives as well as monitoring and management requirements for the MSHCP. The three group definitions are as follows:
Group 1 -- Take coverage is warranted based upon regional or landscape level considerations, such as healthy population levels, widespread distribution throughout the MSHCP Plan Area, and life history characteristics that respond to Habitat-scale Conservation and management actions.
Group 2 -- Take coverage is warranted based on regional or landscape level considerations with the addition of site-specific Conservation and management requirements that are clearly identified in the MSHCP for species that are generally well-distributed, but that have core Habitats that require Conservation.
Group 3 -- Take coverage is warranted based upon site specific considerations and the identification of specific Conservation and management conditions for species within a narrowly defined Habitat or limited geographic area within the MSHCP Plan Area.
Section 9.0 of the MSHCP Plan, Volume I, summarizes the Conservation Strategy for each of the MSHCP Covered Species.
