WOODY PLANT DENSITY <br />"Background" Density <br />(Table B -3) <br />Total average "Background" woody plant density in BRB PSCM -1 was 732.5 stems per acre. Big <br />sagebrush was the densest at 482.8 stems per acre followed by mountain snowberry with 206.4 stems <br />per acre. Five other species of shrub were present, each with densities of 20 stems per acre or fewer. <br />Concentration Area Density <br />(Table B- 4) <br />Total average "Concentration Area" woody plant density in BRB PSCM -1 was 2703.3 stems per acre. Big <br />sagebrush was the densest at 2119.8 stems per acre followed by mountain snowberry with 519.6 stems <br />per acre. Six other species of shrub were present, each with densities of fewer than 35 stems per acre. <br />2011 Mountain Brush Reference Area <br />(Photographs 25 through 28) <br />COVER <br />(Table B -5) <br />Native shrubs were the predominant lifeform observed in the Mountain Brush Reference Area, <br />contributing 62.9 percent total firstl -hit vegetation cover. Of this, Gambel's oak contributed 29.1 percent, <br />mountain snowberry contributed 15.2 percent, and Saskatoon serviceberry contributed 13.9 percent. <br />Native perennial forbs and native perennial cool season grasses made moderate contributions to cover, <br />with 10.9 and 7.3 percent, respectively. Also observed in the area was the noxious weed hound's tongue. <br />Total average vegetation cover for first -hits was 85.3 percent. Allowable first -hit herbaceous cover was <br />21.0 percent. Cover by standing dead, litter, bare soil and rock averaged 0.5, 8.9, 5.3 and 0.0 percent, <br />respectively. Average species density was 40.0 species per 100sq. m. <br />16 <br />
