There aze nine species, Gray Wolf (Canis lupus), Black-Footed Ferret (Mustela nigrines), <br />Grizzly Bear (Ursus arctos), Preble's Meadow Jumping Mouse (Zapus hudsonius preblei), Kit <br />Fox (Vulpes macrotis), Townsend's Big-Eared Bat (Corynorhinus townsendii nallescens), Black- <br />Tailed Prairie Dog (Cvnomvs ludovicianus), Botta's Pocket Gopher (Thomomy bottae rnbidus) <br />and Swift fox (Vulnes yelox), that are not known to occur in Routt County. These species are <br />not known to occur in Routt County, and therefore on site or adjacent to the mine site, due to the <br />lack of sightings and/or habitat. <br />There are three species, Lyme (Lvnx Canadensis), Wolverine (Gulo Qulo) and River Otter <br />(Lutra canadensis), that are either known to occur or likely to occur in Routt County due to <br />sightings and/or habitat. These species were not sighted in the 1979 to 1980 study on site or <br />adjacent to the mine site. <br />Lynx preferred habitat is northern coniferous forests. Uneven-aged stands with relatively <br />open canopies and well-developed understories are ideal. They now appear to be restricted to <br />extremely isolated areas of the mountains of the central portion of Colorado. Lynx have been <br />extirpated in Routt County. <br />Wolverines preferred habitat is boreal forests and tundra. The status of the wolverine <br />range in Colorado is uncertain at this time. Wolverines have been extirpated in Routt County. <br />River otters inhabit riparian habitats that traverse a variety of other ecosystems ranging <br />from semidesert shrublands to montane and subalpine forests. The species requires permanent <br />water of relatively high quality and with an abundant food base offish or crustaceans. Minimum <br />estimated water flows are 10 cubic feet (0.28 cubic meter) per second. Other habitat features that <br />may be important include the presence of ice-free reaches of stream in winter, water depth, <br />stream width, and suitable access to shoreline. They occur in the Colorado, Gunnison, Piedra, <br />and Dolores rivers. River otters abundance in Routt county is rare. <br />As the mine is in permanent cessation no impact to the species in Colorado that are <br />threatened, endangered or species of special concern at the state and/or federal levels or habitat is <br />expected. <br />2.7-28b Revised 11/06 <br />
