2.4.2 Threatened and Endangered Species <br />Publications of the U.S. Fish and Wildlife Service (Jan. 17, 1979 and most recently in 2012), and the <br />Colorado Division of Wildlife (1978, and most recently in 2012) were consulted to determine threatened <br />and endangered wildlife species that could occur on or adjacent to the Trapper Mine mine plan area. in <br />addition, a raptor nesting survey was conducted for the mine plan area and adjacent area during May of <br />1980. Ecology Consultants Inc. baseline data was also examined. There are no areas within or adjacent <br />to the mine plan area that have been or are pending designation as "essential habitat" for any of the <br />threatened or endangered species that could potentially occur there. <br />2.4.2.1 Bald Eagle <br />Bald eagles (Haliaeetus leucoce halus), a previously threatened species, are known to winter along the <br />Yampa River, three miles northwest of the proposed mine plan area, and the Williams Fork River, one <br />mile west of the proposed mine plan area. The U.S. Fish and Wildlife Service (1978) lists the Williams <br />Fork River as a bald eagle wintering area. During big game aerial surveys in January of 1977, 1978 and <br />1979, Trapper Mine environmental personnel noted bald eagles along the Yampa River north and west of <br />the mine plan area. Map M20 illustrates these wintering areas, Through 2012, no known nesting sites <br />have been located within the mine plan area or adjacent areas. In addition, the U.S. Fish and Wildlife <br />Service (1978), Ecology Consultants, Inc. baseline studies and Trapper Mine raptor surveys indicate <br />there is no nesting in the general area by this species. <br />Bald eagles are occasionally seen hunting over reclaimed areas of the mine plan area. They may <br />occasionally use the mine plan area for feeding on carrion during winter months or overflights may occur <br />from the Yampa River to the Williams Fork River. Mining has had no effect on the wintering activities of <br />this species as the mining activities are well removed from the winter concentration areas. <br />2 -141 <br />
