Aspen Reference Area <br />• (Photographs 31 through 35) <br />COVER <br />(Table 2) <br />Native perennial forbs, native trees and native shrubs were the predominant lifeforms observed in <br />the Aspen Reference Area, contributing 75.7, 34.8 and 36.2 percent of the total all-hit vegetation <br />cover respectively. Native trees consisted entirely of aspen (Populus tremuloides). Native <br />perennial forbs consisted mainly of western aniseroot (Osmorhiza occidentalis) and cow parsnip <br />(Heracleum sphondylium ssp. montanum). Native shrubs was predominantly composed of choke <br />cherry (Padus virginiana ssp. melanocarpa), mountain snowberry (Symphoricarpos rotundifolius), <br />and Saskatoon serviceberry (Amelanchier alnifolia). Also observed in the area were the noxious <br />weeds hound's tongue, Canada thistle and bull thistle. <br />Total average vegetation cover for all hits was 159.1 percent. For herbaceous vegetation, total <br />average cover for all hits was 87.3 percent. Cover by standing dead, litter, bare soil and rock <br />averaged 0.4, 6.8, 2.4 and 0.0 percent respectively. Average species density was 33.0 species <br />per 100sq. m. <br />0 <br />Mountain Brush Reference Area <br />(Photographs 31 through 35 ) <br />COVER <br />(Table 3) <br />Native shrubs were the predominant lifeform observed in the Mountain Brush Reference Area, <br />contributing 75.9 percent toward total all-hit vegetation cover. Native shrubs were predominantly <br />composed of Gambel's oak (Quercus gambeliv), mountain snowberry and Saskatoon <br />serviceberry. Native perennial forbs and native perennial cool season grasses made moderate <br />contributions to cover, with 20.6 and 18.1 percent respectively. Also observed in the area were <br />the noxious weeds hound's tongue and Canada thistle. <br />Total average vegetation cover for all hits was 117.7 percent. For herbaceous vegetation, total <br />average cover for all hits was 40.5 percent. Cover by standing dead, litter, bare soil and rock <br />averaged 0.4, 12.5, 4.7 and 0.1 percent respectively. Average species density was 32.6 species <br />per 100 sq. m. <br />• <br />ESCO Assoc. E-9
