• Baseline Technical <br />Report <br />ARCADIS <br />Report for Soils and <br />Biological Resources, <br />Cresson Mine Life Extension <br />Project Area <br />which result in CDOW investigation, damage to persons or property, and/or removal of <br />the problem bear(s). <br />5.2 GAME BIRDS <br />Blue grouse (Dendragapus obscurus) is the only game bird species expected to occur <br />within the District. The north end of the Study Area, with its mix of dense conifer <br />stands, aspen groves, and wet meadows, provides ideal blue grouse habitat. None <br />were observed during the 2007 site visit. <br />5.3 RAPTORS <br />Raptors noted in the Study Area during field surveys in 1999 included red-tailed hawks <br />(Buteo jamaicensis) only. Several were observed soaring or perched. No active nests <br />were observed. Other raptors that may be found in the area but were not observed <br />• during 1996 and 1999 field surveys include northern goshawk (Accipiter gentilis), <br />Cooper's hawk (Accipiter cooperii), sharp-shinned hawk (Accipiter striatus), and golden <br />eagle (Aquila chrysaetos). Raptor surveys were not performed during the 2007 field <br />visit. <br />5.4 OTHER WILDLIFE SPECIES <br />Several small game and nongame species occur in the area and are typical of the <br />high-elevation habitat present, including bird species such as gray jay (Perisoreus <br />canadensis), raven (Corvus corax), great horned owl (Bubo virginanus), magpie (Pica <br />pica), flicker (Colaptes aurates), downy woodpecker (Picoides pubescens), and <br />numerous songbirds; reptile species such as garter snake (Thamnophis spp.); larger <br />mammals such as coyote (Canis latrans), red fox (Vulpes vulpes), raccoon (Procyon <br />lotor), skunk (Mephitis mephitis), mountain lion (Felis concolor); and rodents such as <br />ground squirrel (Spermophilus spp.), pocket gopher (Thomomys spp.), meadow vole <br />(Microtus spp.), cottontail rabbit (Sylvilagus spp.), jackrabbit (Lepus spp.), and deer <br />mouse (Peromyscus spp.). <br />Shafts and adits associated with historic underground mining in the area represent <br />potential bat habitat, as well as abandoned buildings and other unused structures. <br />Suitable foraging habitat for bats exists along Cripple Creek, Arequa Gulch, Squaw <br />Gulch, Wilson Creek, Grassy Creek, and several unnamed drainages on the north end <br />of the District. Several species of bats would be common at this elevation in Colorado. <br />L <br />CCV Final Technical Report (3-28-08).doc 15
