'. <br />primarily on the lower grassland during the winter, later moving to a summer <br />range above the mine. <br />There are about ten beaver dams in a quarter-mile area immediately downstream <br />from the mine. Beaver have been introduced into the area by the company and <br />are active in the spring and summer. Grouse are found on Stony Ridge and on <br />other north-facing slopes. <br />Rainbow and cutthroat trout are abundant and reproduce downstream from the <br />mine, while rainbow trout live upstream as well. <br />No endangered species are known to be present in the mining area, nor is there <br />any critical wildlife habitat or high value habitat. <br />Loadout <br />The pinon-juniper community type occupies slopes and ridge tops over much of <br />the area associated with the truck dump. Pinon pine and Utah juniper form <br />open, low density stands in which both shrub and herbaceous understory are <br />very sparse. The pinon mouse, least chipmunk, and Colorado chipmunk are <br />characteristic of this community. Bobcats may frequent the area searching for <br />rodents, and mule deer and elk traverse the area as they pass from bedding <br />grounds to feeding ground. The most common birds in this community type <br />include the pinon jay, scrub jay magpie, and various raptors. <br />During 1992, the Aspen Glen Company permitted a planned unit development <br />(residential and golf course) on land which included the loadout permit area. <br />A nesting pair of bald eagles was identified on land west of the permit area. <br />The sagebrush community generally associated with deeper soils is also present <br />in the permit area. Herbaceous cover is sparse, although diverse, and may <br />provide limited winter browse for elk and mule deer. Other animal species <br />which may be encountered include the sagebrush vole, least chipmunk, Colorado <br />chipmunk, American bobcat, and the jackrabbit. The most common bird <br />encountered is the sage sparrow, although numerous other species of birds <br />utilize this community for feed and cover. <br />The riparian habitat along the Roaring Fork River, with vegetation dominated <br />by trees such as cottonwoods and willows, is mostly surrounded by developed <br />land. Bird species encountered here included the white-crowned sparrow, <br />Lincoln sparrow, gray-headed junco, and mountain chickadees. Raptors may <br />perch in the taller cottonwoods. Small mammals encountered include the <br />long-tailed vole and an occasional northern pocket gopher. Although not <br />observed, the western jumping mouse may occur. This community is used by deer <br />as loafing area and for protection during winter months. Elk move into these <br />areas during severe winters. <br />Land Use <br />Historically, agricultural communities in the Roaring Fork Valley have <br />produced cattle, sheep, and hay. Today, however, sheep production is <br />extremely limited and, on a relative scale, cattle are now the only <br />significant agricultural commodity exported from the valley. <br />-5- <br />
