~I <br />CJ <br />EXHIBIT J - VEGETATION INFORMATION <br />5~ <br />' GENERAL DESCRIPTION <br />The site is located in Middle Park in Grand County, Colorado, at <br />an elevation of 8,040 feet. The area is surrounded by <br />' cultivated pasture, meadow bottomland, and sagebrush-bunchgrass - <br />vegetation. Two distinct landforms occur within the lease area - <br />an elevated bench which will be the primary source of bedding <br />material and bottomland located to the east and west of the <br />bench. The bench is bordered by east and west facing inclines <br />with slopes of 30-40 percent and a relatively level top (0-2 <br />' percent slopes). The bottomland is underlain by deep alluvial <br />soil and is predominantly level with 0-2 percent slopes. <br />' VEGETATION DESCRIPTION <br />Bench Area <br />' Vegetation of the bench is dominated primarily by sagebrush and <br />secondarily by a variety of bunchgrasses. The dominant shrub is <br />Vasey Big Sagebrush (Artemisia tridentata ssp. vaseyana). Other <br />' prominent shrubs are Rubber Rabbitbrush (Chrysothamnus nauseosus) <br />and Douglas Rabbitbrush (Chrysothamnus viscidiflorus). Wax <br />Currant (gibes cereum) occurs intermittently on the bench. A <br />' prominent subshrub on the bench, especially on the drier slope <br />with a west aspect, is Fringed Sage (Artemisia frigida). Other <br />subshrubs present include Sulphurflowerer (Eriogonum umbellatum) <br />' and Woods Rose (Rosa woodsii). <br />Junegrass (Koeleria cristata), Bearded Bluebunch Wheatgrass <br />(Agropyron spicatum), and Letterman Needlegrass (Stipa lettermanii <br />' dominate the existing grass component. Other associated grasses <br />are Thickspike Wheatgrass (Agropyron dasystachyum), Western <br />Wheatgrass (Agropyron smithii)~ Nodding Brome (Bromus anomalus), <br />' Mountain Brome (Bromus marginatus), and Sandberg Bluegrass (POa <br />secunda). The grasslike Sedge (Carex sp.) is also very evident <br />on the bench. <br />Forbs do not comprise a large component of the total vegetation <br />cover but their presence is conspicuous. Sagebrush Buttercup <br />(Ranunculus glaberrimus), Groundsel (Senecio multilobatus), and <br />' Douglas Chaenactis (Chaenactis douglasii) are the dominant forbs <br />at this time of year (mid-April). Other forbs on the bench <br />include Windflower (Anenome sp.), Rose Pussytoes (Antennaria <br />' rosea), Aster (Aster sp.), Starry Cerastium (Cerastium arvense), <br />Thistle (Cirsium sp.), Fernleaf Fleabane (Erigeron compositus), <br /> <br />' J-1 <br />
