<br />........ ". n "1(,) <br />~~ :.1 _.. ......; u J <br /> <br />II <br /> <br />ALPINE - Made up of grasses, grass-like forbs, and cushion plants generally growing <br />above 1',600 feet. Boulder fields and rock outcrops are common. <br /> <br />CONIFEROUS FORE3i - Includes pure and mixed stands of Engelmann spruce and lodgepole <br />pine. Douglas fir is often found in association with these two species. Altitudinal <br />ranges of 9.000 to 11,600 feet are common with spruce generally occupying the higher <br />and/or more moist sites. LOdgepole is more prevalent in lower elevations and better <br />drained soils. <br /> <br />ASPEN FOREST - Occurs in pure stands and mixed with conifer. Aspen is opportunistic <br />and often is the first species to revegetate areas after disturbances such as fife <br />and avalanche. Its usual altitudinal range is 9,000 to 11,500 feet. If normal plant <br />succession is allowed to take place. spruce and a1pine fir will usually replace the <br />aspen. <br /> <br />SAGEBRUSH-SHRUB ~ Occurs on drier south. east, and west aspects with an altitudinal <br />range of B,OOO to 9,800 feet. Big Sage is the principal shrub species. Big game winter <br />habitat is often identified wtth this type. <br /> <br />GRASSLAND - Comprised primarily of bunchgrasses. it occurs on all aspects between 9.000 <br />and 11,000 feet on moderately moist sites with average to good soils. <br /> <br />ROCKLAND - Contains none to only sparsely scattered trees, shrubs. and grasses. Occurs <br />on all aspects between about 9.000 and 11,600 feet elevation. <br /> <br />IRRIGATED MEADOW. Those areas of improved pasture, usually managed for hay production, <br />located on valley flood plains. <br /> <br />Areas and ownership of the vegetative cover types are summarized in the following table: <br /> <br /> VEGETATIVE APPROXI:1ATE % in N.

Wild1 ife and Fish <br /> <br />Because of the wide range of environmental conditions. a great variety of wildlife is <br />represented. Big game species include elk, mule deer. bighorn sheep, and black bear. <br /> <br />Small game and non-game species identified are numerous. <br />include the sage grouse,_ Brewerl s sparrow, goshawk, downy <br />and yellow bellied marmot. <br /> <br />Some of the more typical <br />woodpecker. pika. pine squirrel, <br /> <br />Aquatic habitat includes twenty-six laKes of varying size and depth and 134 miles of <br />streams which can sustain cold-water fish populations. Many small, usually stagnant, <br />ponds and marshes are present. particularly in glaciated alpine and SUbalpine regions. <br /> <br />3. Threatened or EndanGered Species <br /> <br />a. Fauna <br /> <br />The list of threatened and endangered species ap~earing in the Federal Register <br />ha~ been reviewed. No species found on this list is known to inhabit the area <br />with the exception of an occasional mi~rant bald eagle during the winter or early <br />spring months. There are no known eagle nesting sites in the general vicinity. <br />American peregrine falcon could occur in the llOit, however, no nesting pairs have <br />been observed to date. <br /> <br />The Colorado cutthroat has not been observed in the annual creel census done within <br />the unit. It is likely that if the species did exist in t~e past, it would now <br />be hybridized with other introduced trout species. <br /> <br />There are no prairie dog towns of sufficient size within the unit to support black- <br />footed ferret. <br /> <br />10 <br />
