Total average vegetation cover, for first hits, was 36.2 percent. Total average vegetation cover, <br />for all hits, was 37.7 percent. Standing dead, litter, bare soil, and rock each had 1.2, 19.3, 41.8, <br />and 1.5 percent cover, respectively. Average species density was 26.7 species per 100 sq.m. <br />Production <br />(Table 5) <br />Total average production was 1391.8 Ibs per acre. Native perennial cool season grasses <br />contributed the most with an average production of 785 Ibs per acre. Introduced annual grasses <br />and introduced annual and biennial fortis contributed a moderate amount with 307 and 175 Ibs <br />per acre respectively. Native annual and biennial fortis, native perennial fortis, introduced <br />perennial fortis and introduced perennial cool season grasses were present at less than 100 <br />pounds per acre each. <br />Woody Plant Density <br />(Table 6) <br />Total average density of woody plants was 52.6 stems per acre, composed entirely of native <br />shrubs. Big sagebrush (Seriphidium tridentatum) was the most abundant, with 30.4 stems per <br />acre. Prickly rose (Rosa says), mountain snowberry (Symphoricarpos rotundifolius), antelope <br />bitterbrush (Purshia tridentata), and Rocky Mountain maple (Acer glabrum) were also present, <br />each with less than 10 stems per acre. <br />Reference Areas <br />ASPEN REFERENCE AREA <br />(Photographs16-25 in Appendix 5) <br />Cover <br />(Table 7) <br />Native perennial fortis were most abundant, contributing 39.3 percent toward the total 113.4 <br />percent vegetation cover (all hits). Within this group, western aniseroot (Osmorhiza occidentalis), <br />mountain bluebells (Mertensia ciliata), and serrate groundsel (Senecio Serra) were most <br />extensive, having 7.7, 5.3, and 4.0 percent cover (all hits), respectively. Native shrubs composed <br />26.0 percent of total vegetation all-hit cover. Mountain snowberry (Symphoricarpos rotundifolius), <br />chokecherry (Padaus virginiana ssp. melanocarpa), and Saskatoon serviceberry (Amelanchier <br />alnifolia) were the dominant native shrubs with 14.0, 3.9, and 7.2, percent total vegetation all-hit <br />cover, respectively. Native perennial cool season grasses, provided 19.9 percent cover, of which <br />most was blue wildrye (Elymus g/aucus), with 10.8 percent all hit cover. Quaking aspen (Populus <br />8 <br />
