MOUNTAIN BRUSH EXTENDED REFERENCE AREA <br />(Photographs 29 -38, Tables 8 -9) <br />Cover <br />(Table 8) <br />Native shrubs were most abundant, comprising 59.1 percent all -hit vegetation cover. Within this group, <br />Gambel's oak (Quercus gambelii), mountain snowberry (Symphoricarpos rotundifolius), Saskatoon <br />serviceberry (Amelanchier alnifolia), and chokecherry (Padus virginiana ssp. melanocarpa) were most <br />common, having 28.6, 17.7, 5.7, and 5.5 percent cover respectively. Native perennial cool season <br />grasses were the second most abundant group contributing 18.4 percent toward total all -hit vegetation <br />cover, dominated by Agassiz bluegrass (Poa pratensis ssp. agassizensis) with 6.5 percent cover and elk <br />sedge (Carex geyen) with 5.6 percent cover (all- hits). Native perennial forbs were the third most <br />abundant lifeform contributing 10.5 percent toward total all -hit vegetation cover, having numerous species <br />with low percent cover values and no dominant species. Tailcup lupine (Lupinus caudatus), showy <br />fleabane (Erigeron speciosus), James starwort (Pseudostellaria jamesiana) had the highest percent cover <br />values of this group (2.0, 1.5, and 1.5 percent, respectively). <br />Total average vegetation cover, for first hits, was 65.7 percent. Total average vegetation cover, for all hits, <br />was 89.6 percent. Standing dead, litter, bare soil, and rock each had 1.7, 20.7, 11.6, and 0.3 percent <br />cover, respectively (first hits). Average species density was 27.6 species per 100 sq.m. <br />Production <br />(Table 9) <br />Total average production was 692.3 Ibs per acre. Native perennial cool season grasses contributed the <br />most with an average production of 342.6 Ibs per acre. Native perennial forbs and introduced annual <br />grasses contributed 330.1 and 14.3 Ibs per acre respectively. Introduced annual and biennial fortis, <br />native annual and biennial forbs, and introduced perennial cool season grasses were also present, each <br />with less than 6.0 pounds per acre. <br />SAGEBRUSH EXTENDED REFERENCE AREA <br />(Photographs 39 -48, Tables 10 -11) <br />Cover <br />(Table 10) <br />Native shrubs were the most abundant lifeform in the Sagebrush Extended Reference Area, making up <br />38.4 percent toward the total 64.4 percent vegetation cover (all hits). Within this group, big sagebrush <br />(Artemisia tridentata) and mountain snowberry (Symphoricarpos rotundifolius) were most abundant, <br />having 22.6 and 12.4 percent total vegetation all -hit cover, respectively. Native perennial forbs were the <br />second most abundant group contributing 13.8 percent total vegetation all -hit cover, comprised by <br />numerous species with low percent cover values and lacking dominant species. Arrowleaf balsamroot <br />(Balsamorhiza sagittata), chokecherry lupine (Lupinus prunophilus), and weedy milkvetch (Astragalus <br />E <br />
