This species has undergone long term population declines, beginning in the 1970's and continuing through the 1990's (Hammerson 1999). Its habitat is wet areas at marshes, stream sides, beaver ponds, kettle ponds and lakes set in subalpine forests. Hammerson (1999) references historical records in the Flat Tops a few miles west of the Project site. The elevation of the Project site is primazily between 8,400' to 8,600' at the lower edge of the range of this species, and far from the subalpine forest. The probability of occurrence is low, and habitats of value include Egeria Creek and associated Graminoid Wetlands, and possibly the pond in the Middle Drainage. Northern leopard frogs live in damp Graminoid Wetland/Aquatic and Riparian Shrubland habitat adjacent to open water. They breed in quiet waters along the vegetated margins of ponds, sloughs, and streams (Hammerson 1999). The probability of occurrence on the Property is moderate along Egeria Creek, and possibly the pond in the Middle Drainage. The bald eagle migrates through the area in spring and fall, and hunts carrion during the winter. The probability of occurrence on [he Property is low to moderate, and likely is on an infrequent basis since there are not large bodies of water on the property. Egeria Creek and the pond aze the primary habitats of value to this species. Sage Grouse are year round residents and are most common in the Sagebrush Shrubland habitat. In late summer as the upland habitats dry out, the grouse will move into the
