West Elk Mine • 2.0411 Fish and Wildlife Resources Information During the mid-1970's numerous studies were undertaken on the permit and adjacent area to identify and describe the wildlife resources of these areas. These investigations included aerial surveys and road counts for big game (elk, deer, and black beaz), strip transects for small animals, direct observation for bird species, and aquatic samples for riverine organicmc. Through these studies, database searches in 2003 and 2004, and consultation with the Colorado Division of Wildlife (CDOW) and the U.S. Fish and Wildlife Service (IISFWS), it was determined that the mining operation would not significantly affect wildlife populations in the permit and adjacent area. For federally listed wildlife species, the permit area inctndes bald eagle winter range, and bald eagle winter concentration area has been mapped by CDOW along the North Fork of the Gunnison River. Lynx habitats have been mapped by USFS in about half of the permit area. There is no designated critical habitat for any federally listed wildlife species. CDOW has mapped critical winter range for elk along the north edge of the permit area, and for mule deer in a few small locations on the west edge. There are no identified big game production areas or migration routes. Lists of mammals, birds, and reptiles and amphibians potentially occurring on the permit and adjacent area have been compiled firm field studies, Colorado Division of Wildlife publications (CDOW, I990; 1987; 1981} and standard zoological references (Fitzgerald et aL, 1994 for mammals, Kingery,1998 for birds, and Hammerson,1999 for reptiles and amphibians) and are presented as Table 25, Table 26, and Table 27. • Big Game Tbree big game species, mule deer (Odocoileus hemiomcs), American elk (Cervus canadertsis), and black bear (Ursus americmrus), have been documented on the West Elk Mine study area during field studies from November 1975 through February 1979, and in September 1993. IVlonntain lion (Fells concolor) also undoubtedly Decor. The area appears to produce a relatively large number of big game compared to other areas in Colorado and consequently provides many hours of recreational activity each hunting season. Mieratorv Routes No deer or elk migratory routes are lmown to exist within the permit area. A discussion of migratory routes would refer to big game species (mule deer and elk in particulaz), since most other wildlife species either do not migrate (most small and medium-sized mammals and some birds), or they migrate totally into and out of the area seasonally. Preferred Habitat Information on preferred habitats is presented on Map 48 for the habitat preferences of big game, medium-sized mammals, small mammals and birds. A map of the available habitats withia the affected area appears as Map 42. • 2.04-162 Revised \niianber 2004 PRIG
