COVER <br />(Table 8) <br />Introduced perennial cool season grasses were the predominant lifeforms observed in the Phase <br />II Bond Release Area, contributing 10 percent first-hit vegetation cover. Native perennial forbs, <br />introduced perennial forbs, and native perennial cool season grasses contributed 3, 6, and 7 <br />percent cover, respectively. Introduced perennial cool season grass cover was composed mostly <br />of orchard grass (Dactylis glomerata) and smooth brome (Bromopsis inermis). Native perennial <br />cool season grass cover was predominantly composed of thickspike wheatgrass (Elymus <br />lanceolatus fm. dasystachya), western wheatgrass (Pascopyrum smithii) and basin wildrye <br />(Leymus cinereus). Introduced perennial forb cover total was composed mostly of alfalfa <br />(Medicago sativa). <br />Total average vegetation cover for first hits was 33.9 percent. For herbaceous vegetation, total <br />average cover for first hits was 33.1 percent. Cover by standing dead, litter, bare soil and rock <br />averaged 4, 27, 31 and 5 percent, respectively. Average species density was 29.9 species per <br />. 100 sq. m. <br />Mountain Brush Reference Area <br />(Photographs 65 through 68, 73 ) <br />COVER <br />(Table 9) <br />Native shrubs were the predominant lifeform observed in the Mountain Brush Reference Area, <br />contributing 64.2 percent toward total first-hit vegetation cover. Of this, Gambel's oak (Quercus <br />gambelip contributed 27.4 percent, Saskatoon serviceberry (Amelanchier alnifolia) contributed <br />16.6 percent, and mountain snowberry (Symphoricarpos rotundifolius) contributed 11.0 percent. <br />Also observed in the area were the noxious weeds houndstongue (Cynoglossum officinale), and <br />Canada thistle (Breea arvensis). <br />• 17 <br />
