Volume III Appendix T – San Juan National Forest Biological Evaluation and T-ii Bureau of Land Management Sensitive Species Analysis Final Environmental Impact Statement 1 U.S. FOREST SERVICE TERRESTRIAL WILDLIFE BIOLOGICAL EVALUATION 1.1 Introduction This biological evaluation (BE) discloses the potential influences on the revision of the U.S. Forest Service (USFS) San Juan National Forest (SJNF) Land and Resource Management Plan (LRMP) on USFS Rocky Mountain Region (Region 2) sensitive. The list of Region 2 Regional Forester sensitive species was updated on June 10, 2011. The Forest Service Manual (FSM) 2670 directs the USFS to develop and implement management practices to ensure that sensitive species do not become threatened or endangered because of USFS actions (FSM 2670.22). Sensitive species are those plant and animal species identified by a Regional Forester for which population viability is a concern as evidenced by a) significant current or predicted downward trends in population numbers or density or b) significant current or predicted downward trends in habitat capability that would reduce a species' existing distribution (FSM 2670.5). FSM 2670 directs the USFS to prepare BEs for projects, as part of the National Environmental Policy Act of 1969 (NEPA) process, to determine the potential effects from those projects on sensitive species and to ensure that USFS actions do not contribute to loss of viability of threatened, endangered, proposed, or sensitive plant and animal species or contribute to a trend towards federal listing of any species under the Endangered Species Act (ESA) (FSM 2672.41 and 2670.32). A BE is as a documented review of USFS programs or activities in sufficient detail to determine how an action or proposed action may affect any threatened, endangered, proposed, or sensitive species (FSM 2670.5). 1.1.1 Project Description The LRMP would guide relevant resource management programs, practices, uses, and protection measures. The associated Final Environmental Impact Statement (FEIS) examines potential environmental effects that could occur as a result of implementing projects associated with the LRMP. The key decisions made in this integrated plan for long-term management of the SJNF are: • Establishment of desired outcomes, including multiple-use goals and objectives. • Establishment of management requirements, including criteria that would be applied to guide day-to- day activities. These are primarily expressed as standards and guidelines and other design criteria. • Establishment of management area direction, including identifying allowable uses, or allocations, restrictions, and prohibitions. All lands within the planning area are allocated to one of seven management areas, or zones, that reflect different levels of development and suitable uses or activities. • Designation of suitable timber land and establishment of allowable sale quantity. • Establishment of monitoring and evaluation requirements. 1.1.2 Project Area The project area is the SJNF boundary, located in southwest Colorado at the junction of the Southern Rockies and the Colorado Plateau ecoregions. The Colorado Plateau portion is characterized by sedimentary geology dominated by deep canyons and mesas. The Southern Rocky Mountains portion is characterized by mountains with mixed geology. Life zones represented in the planning area include Semi- Desert, Lower Montane, Upper Montane, Subalpine, and Alpine. The area encompasses about 1,864,831 acres of National Forest Service (NFS) land and includes lands in Archuleta, Conejos, Dolores, Hinsdale, La Plata, Mineral, Montezuma, Montrose, Rio Grande, San Juan, and San Miguel Counties. The west border of the planning area is the Utah state line. The southern border of the planning area is the New Mexico state Volume III Appendix T – San Juan National Forest Biological Evaluation and Bureau of Land Management Sensitive Species Analysis T-1 Final San Juan National Forest and Proposed Tres Rios Field Office Land and Resource Management Plan line. The eastern border is the Continental Divide. The northern border covers the administrative boundaries with the Rio Grande, Gunnison, Grand Mesa, and Uncompahgre National Forests. 1.1.3 Alternatives Four issues drove the development of four alternatives: • Issue 1. Balancing Management between the Ideas of Maintaining “Working Forest and Rangelands” and Retaining “Core Undeveloped Areas” • Issue 2. Providing for Recreation and Travel Management within a Sustainable Ecological Framework • Issue 3. Management of Special Areas Designations and Unique Landscapes • Issue 4. Oil and Gas Leasing and Development The four alternatives are summarized below: Alternative A (No Action): Alternative A represents the continuation of current management direction under the existing USFS land management plans. Alternative A meets the requirements of NEPA (40 Code of Federal Regulations [CFR] 1502.14) that a No Action Alternative be considered. “No Action” means that the alternative reflects the implementation of existing management goals, objectives, and management practices based on the existing land use plans. Alternative A also serves as the baseline for comparing and contrasting the impacts of the other alternatives. Alternative A is based on reasonably foreseeable actions, existing planning decisions and policies, and existing land use allocations and programs. The activities projected under Alternative A are based more on historical and expected output levels than on projections of outputs from the earlier land management plans. For example, the SJNF has been selling about one-half as much timber as was estimated in the existing plan due to both budget constraints and lower demand for wood products and periodically revised adjustments of the capacity of the SJNF to supply timber. Continuation of current management reflects this adjustment to program activities. Alternative B (Preferred Alternative): Alternative B, the Preferred Alternative, provides for a mix of multiple-use activities, with a primary emphasis on maintaining most of the large, contiguous blocks of undeveloped lands, enhancing various forms of recreation opportunities, and maintaining the full diversity of uses and active forest and rangeland vegetation management. Alternative B focuses on balancing the goals
