Analysis of effects is tiered to the 2001 Sierra Nevada National Forest Plan Amendment. Fresno and Tulare Counties Federally listed species covered by the Endangered Sequoia National Forest, Giant Sequoia National Species Act are addressed in a separate document Monument (Biological Assessment). Species addressed and determinations are summarized in the following table: Species Status Determination Northern goshawk FSS, All Alternatives: may affect individuals, not likely to result in a trend (Accipiter gentilis) CSSC toward Federal listing or loss of viability. Little willow flycatcher FSS, Alternative A: will have no effect. (Empidonax trailii brewsterii) SE Alternatives B, C, D, E, and F: may affect individuals, not likely to result in a trend toward Federal listing or loss of viability. Bald eagle FSS, Alternatives A, B, C, D, and E: will have no effect. (Haliaeetus leucocephalus) SP, SE Alternative F: may affect individuals, not likely to result in a trend toward Federal listing or loss of viability. Great gray owl FSS, All Alternatives: may affect individuals, not likely to result in a trend (Strix nebulosa) SE toward Federal listing or loss of viability. California spotted owl FSS, All Alternatives: may affect individuals, not likely to result in a trend (Strix occidentalis CSSC toward Federal listing or loss of viability. occidentalis) Pallid bat FSS, All Alternatives: may affect individuals, not likely to result in a trend (Antrozous pallidus) CSSC toward Federal listing or loss of viability. Townsend’s big eared bat FSS, All Alternatives: will have no effect. (Corynorhinus townsendii CSSC townsendii) Western red bat FSS, All Alternatives: may affect individuals, not likely to result in a trend (Lasiurus blossevillii) CSSC toward Federal listing or loss of viability. California wolverine FSS, All Alternatives: may affect individuals, not likely to result in a trend (Gulo gulo luteus) ST, SP, toward Federal listing or loss of viability. FC American marten FSS, All Alternatives: may affect individuals, not likely to result in a trend (Martes americana) CSSC toward Federal listing or loss of viability. Pacific fisher FSS, All Alternatives: may affect individuals, not likely to contribute toward a (Martes pennanti pacifica) FC, further downward trend or a loss of viability. CSSC Relictual slender salamander FSS, All Alternatives: may affect individuals, not likely to result in a trend (Batrachoceps relictus) CSSC toward Federal listing or loss of viability. Foothill yellow-legged frog FSS, Alternatives A, B, C, D, and F: will have no effect. (Rana boylii) CSSC Alternative E: may affect individuals, not likely to result in a trend toward Federal listing or loss of viability. Volume 2 Giant Sequoia National Monument, Final Environmental Impact Statement, Appendices 722 Appendix M—Wildlife Biological Evaluation Species Status Determination Mountain yellow-legged frog FSS, Alternatives A, B, C, D, and F: will have no effect. (Rana muscosa) FC, Alternative E: may affect individuals, not likely to result in a trend CSSC toward Federal listing or loss of viability. Southwestern pond turtle FSS, All Alternatives: may affect individuals, not likely to result in a trend (Actinemys marmorata CSSC toward Federal listing or loss of viability. pallida) California legless lizard FSS, All Alternatives: may affect individuals, not likely to result in a trend (Anniella pulchra) CSSC toward Federal listing or loss of viability. Listing Status Key: FE=Federally Endangered, FT=Federally Threatened, FC=Federal Candidate SE=State Endangered, ST=State Threatened, SP=State Fully Protected, CSSC=Species of Special Concern FSS=U.S. Forest Service Region 5 Sensitive Species Species listed as Threatened, Endangered, or Introduction Proposed for listing (Listed species) under the This Biological Evaluation (BE) documents analysis Endangered Species Act (ESA) by the U.S. Fish of programmatic direction (long-term goal and and Wildlife Service (USFWS) are addressed in a objective based management) rather than individual separate document (Biological Assessment [BA] for projects under the Giant Sequoia National Monument the Monument Plan FEIS). USFWS candidates for (GSNM) Management Plan (Monument Plan) listing under the ESA are included with Forest Service Final Environmental Impact Statement (FEIS). Sensitive species in this document. A determination is made on potential effects to This BE was prepared in accordance with Forest wildlife species listed as Sensitive by the Regional Service Manual (FSM) direction 2672.42. Species that Forester, Pacific Southwest Region, USDA Forest were evaluated are shown in Table 1. Service for the Sequoia National Forest. Site-specific documentation will occur for all individual projects carried out under this programmatic direction.
