Introduced perennial cool season grasses were the predominant lifeform observed in the 2005 <br />Reclaimed Area, contributing 14.8 percent toward total first-hit vegetation cover. Of this, nearly <br />10.0 percent was intermediate wheatgrass (Thinopyrum intermedium) and 3.8 percent was <br />smooth brome (Bromopsis inermis). Introduced annual grasses contributed 8.2 percent toward <br />total first-hit vegetation cover. The total was composed of cheat grass (Anisantha tectorum) (6.6 <br />percent) and Japanese brome (Bromus japonicas) (1.6 percent). Additionally, native perennial <br />cool season grasses contributed 7.8 percent toward total first-hit vegetation cover, consisting <br />primarily of (Elymus lanceolatus fm. dasystachya) (2.8 percent) and western wheat grass <br />(Pascopyron smithiil) (1.6 percent). Also observed in the area were houndstongue (Cynoglossum <br />officinale) and Canada thistle (Breea arvensis). <br />Total average vegetation cover for first hits was 36.2 percent. For herbaceous vegetation, total <br />average cover for first hits was 35.4 percent . Cover by standing dead, litter, bare soil and rock <br />averaged 1.4, 12.2, 36.0 and 14.2 percent, respectively. Average species density was 21.2 <br />species per 100sq. m. <br />PRODUCTION <br />(Table 5) <br />Total herbaceous production in 2007 was 1,407.9 pounds per acre. Of this, 538.9 pounds were <br />Introduced perennial cool season grasses, 456.8 were native perennial cool season grasses, <br />165.9 were introduced perennial (orbs, and 146.3 were introduced annual grasses. Three other <br />lifeforms were K~resent at less than 53 pounds per acre. <br />WOODY PLANl~ DENSITY <br />(Table 6) <br />Total average vvoody plant density in the 2005 Reclaimed Area was 380.4 stems per acre. Big <br />sagebrush (Seriphidium tridentatum) was the densest at 299.5 stems per acre. Mountain <br />snowberry (Syrnphoricarpos rotundifolius) contributed 40.5 stems per acre to the total. Two <br />other species cf shrub were present, each with densities of fewer than 33 stems per acre. <br />Mountain Brush Reference Area <br />(Photographs 1~6-20) <br />i 10 <br />
