Total average vegetation cover, for first hits, was 40.7 percent. Total average vegetation cover, <br />for all hits, was 43.4 percent. Standing dead, litter, bare soil, and rock each had 2.7, 25.6, 30.9, <br />and 0.2 percent cover, respectively (first hits). Average species density was 22.3 species per 100 <br />sq.m. <br />Percent all-hit cover (absolute) by herbaceous species as corrected for "allowable" annual and <br />biennial cover (i.e., no more than 10 percent relative cover allowed, See CDMG 1995, 1.IV.A.) <br />and noxious weeds was 35.3 percent, which is just below the 2007 reference area all-hit cover <br />standard of 37 percent. <br />Production <br />(Table 8) <br />Total average production was 1,147.4 Ibs per acre. Introduced perennial cool season grasses <br />contributed the majority with an average production of 1077.8 Ibs per acre. Native annual and <br />biennial forbs, introduced annual and biennial forbs, native perennial forbs, introduced perennial <br />forbs and native perennial cool season grasses were also present, each with less than 22 Ibs per <br />acre. <br />Herbaceous production as corrected for "allowable" annual and biennials (i.e, no more than 10 <br />percent production allowed, See CDMG 1995, 1.IV.A.) and noxious weeds was 1147 pounds per <br />acre, well above the 2007 reference area herbaceous production performance standard of 846 <br />pounds per acre. <br />MOUNTAIN BRUSH EXTENDED REFERENCE AREA <br />(Photographs 22-26) <br />Cover <br />(Table 9) <br />Native shrubs were most abundant, comprising 67.4 percent toward total all-hit vegetation cover. <br />Within this group, Gambel's oak (Quercus gambelii) was most abundant contributing 40.6 percent <br />total all-hit cover. Mountain snowberry (Symphoricarpos rotundifolius), chokecherry (Padus <br />virginiana ssp. me/anocarpa), and Saskatoon serviceberry (Amelanchier alnifolia) were common, <br />having 10.2, 8.8, and 7.0 percent cover, respectively. Native perennial cool season grasses was <br />the second most abundant group (26.0 percent all-hit cover), dominated by elk sedge (Carex <br />geyen) (11.6 percent all-hit cover) and Agassiz bluegrass (Poa agassizensis) (8.2 percent all-hit <br />cover). Native perennial forbs were the third most abundant lifeform (12.2 percent all-hit cover), <br />having numerous species with low percent cover values and no dominant species. Northern <br />bedstraw (Galium septriona/e) and one-flower woodsunflower (Helianthe/la uniflora) had the <br />highest percent cover values of this group (2.6 and 1.4 percent all-hit cover, respectively). <br />9 <br />
