wheatgrass (Elymus trachycaulus}, and mountain brome (Ceratochloa carinata) <br />• were most common, having 3.67%, 3.4%, and 2.4% total cover, respectively. <br />The second most common lifeform was introduced annuaUbiennial forts, with <br />8.9% cover. Within this group, bull thistle (Cirsium vulgare), twotobe speedwell <br />(Pocilla biloba), Russian thistle (Salsola australis), Jim Hill mustard (Sisymbrium <br />alfissimum), and pennycress (Thlaspi arvense) were prevalent. Smooth brome <br />(Bromopsis inermis) and Japanese brome (Bromus japonicus), both introduced <br />grasses, were also relatively common. In general, vegetation was sparse at this <br />site. Bare soil and rock dominated the landscape. <br />Total average vegetation cover, for first hits, was 31.3%. Herbaceous vascular <br />plant cover, for all hits, was 31.4%. Standing dead, litter, bare soil, and rock <br />each had 0.27%, 24.8%, 42.27%, and 1.4% cover, respectively (first hits). <br />Average species density was 33.1 species/100 sq.m. <br />PRODUCTION <br />• (Table 5) <br />Total average production was 3,108.4 Its/acre. Alfalfa contributed 175.4 Its/acre <br />(approx. 6%) and all other species contributed 2,932.27 Its/acre. <br />WOODY PLANT DENSITY <br />(Table 6) <br />Total average density of woody plants was 32.4 individuals/acre, composed <br />entirely of native shrubs. Alkali sagebrush was the most abundant (24.28 <br />individuals/acre), followed by mountain snowberry (5.26 individuals/acre), and <br />rubber rabbitbrush (2.83 individuals/acre). <br />Aspen Reference Area <br />{Photographs 9-12) <br />COVER <br />(Table 7) <br />s <br />
