The management direction proposed in the action alternative would apply to designated BSSG habitats and linkage areas within the project area that have been identified as grouse habitat. However, there are no areas designed as linkage areas within the project area. The analysis area consists of 650,746 total acres of identified BSSG habitat on USFS and BLM lands (Table 3). Of these, about 426,809 acres (66%) occur on Forest Service lands and 223,935 acres (44%) are on BLM lands. Both the Bridgeport and Carson Ranger Districts on the HTNF contain BSSG habitat, as do both the Carson City and Battle Mountain BLM Districts. Federal, state, and private ownerships occur within and outside the National Forest and BLM District boundaries, and include sage-grouse habitat. Summary of Determinations • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project may affect, but is not likely to adversely affect Sierra Nevada bighorn sheep or its critical habitat. • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project will not affect the following Federally-listed species or their designated critical habitat: o Carson wandering skipper, southwestern willow flycatcher, mountain yellow-legged frog (Southern California DPS), Yosemite toad, least Bell’s vireo. • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project is not likely to jeopardize the continued existence of the following species proposed for federal listing, and is not likely to destroy or adversely modify proposed critical habitat: o Greater sage-grouse , Bi-State DPS; Sierra Nevada yellow-legged frog • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project may affect individuals, but is not likely to result in a trend toward Federal listing or loss of viability for the following sagebrush-associated sensitive species in the planning area: : o Pygmy rabbit, dark kangaroo mouse, desert bighorn sheep, loggerhead shrike, sage thrasher, and Brewer’s sparrow. • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project may affect individuals, but is not likely to result in a trend toward Federal listing or loss of viability for the following pinyon-juniper-associated sensitive species in the planning area: o Pinyon jay, ferruginous hawk, pallid bat, Townsend’s big-eared bat silver-haired bat, hoary bat, California myotis, western small-footed myotis, long-eared myotis, fringed myotis, long-legged myotis, Yuma myotis, western pipistrelle. • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project will not affect all other Regional Forester’s and Nevada BLM sensitive species considered in this Biological Evaluation/Biological Assessment. DRAFT DRAFT • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project will benefit habitat and will not cause populations to trend downward, for the following Management Indicator Species (MIS): o Greater sage grouse • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment , the action alternatives may impact habitat, but will not cause populations to trend downward, for the following Management Indicator Species (MIS): o Mule deer • It is my determination that the Greater Sage-Grouse Bi-State Distinct Population Segment Forest Plan Amendment project will have no impact on all other MIS species considered in this assessment. • It is my determination
