Sagebrush/Snowberry Reference Area <br />• (Photographs 36 through 40) <br />COVER <br />(Table 4) <br />Native shrubs were the predominant lifeform observed in the Sagebrush/Snowberry Reference <br />Area, contributing 30.9 percent toward total all-hit vegetation cover. Of this total, mountain <br />snowberry contributed 17.5 percent and big sagebrush (Seriphidium tridentatum) contributed 13.0 <br />percent. Native perennial forbs and native perennial cool season grasses made moderate <br />contributions to cover, with 20.2 and 12.6 percent respectively. Also observed in the area was <br />the noxious weed hound's tongue. <br />Total average vegetation cover for all hits was 66.7 percent. For herbaceous vegetation, total <br />average cover for all hits was 36.3 percent. Cover by standing dead, litter, bare soil and rock <br />averaged 2.5, 28.9, 6.4 and 0.1 percent respectively. Average species density was 20.5 species <br />per 100sq. m. <br />• Steep Mountain Brush Reference Area <br />(Photographs 31 through 35) <br />COVER <br />(Table 5) <br />Native shrubs were the predominant lifeform observed in the Steep Mountain Brush Reference <br />Area, contributing 26.1 percent toward total all-hit vegetation cover. Native shrubs were <br />predominantly composed of big sagebrush, Gambel's oak, birchleaf mountain mahogany <br />(Cercocarpus montanus), and Saskatoon serviceberry. Native perennial cool season grasses <br />made moderate contributions to cover with 12.2 percent. Also observed in the area was the <br />noxious weed hound's tongue. <br />Total average vegetation cover for all hits was 43.5 percent. For herbaceous vegetation, total <br />average cover for all hits was 17.3 percent. Cover by standing dead, litter, bare soil and rock <br />averaged 2.7, 20.9, 27.2 and 9.5 percent, respectively. Average species density was 26.2 <br />species per 100 sq. m. <br />• <br />ESCO Assoc. E-10
