Total average vegetation cover for first -hits was 63.5 percent. Allowable first -hit herbaceous vegetation <br />cover was 59.7 percent. Cover by standing dead, litter, bare soil and rock averaged 0.1, 17.5, 16.3, and <br />2.6 percent, respectively. Average species density was 25.7 species per 100 sq. m. <br />PRODUCTION <br />(Table A -2) <br />Total herbaceous production in 2011 was 2,193.0 pounds per acre. Of this, 815.5 pounds were <br />introduced perennial cool season grasses. Native perennial cool season grasses and introduced <br />perennial forbs were the only other lifeforms functioning as significant producers, contributing 685.2 and <br />439.0 pounds per acre respectively. Five other lifeforms were present, each less than 100 pounds per <br />acre. <br />WOODY PLANT DENSITY <br />Background Density <br />(Table A -3) <br />Total average "Background" woody plant density in BRB -5 was 554.4 stems per acre. Mountain <br />snowberry (Symphoricarpos rotundifolius) was the densest at 206.4 stems per acre followed by big <br />sagebrush (Seriphidium tridentatum) with 132.3 stems per acre. Four other species of shrub were <br />present, each with densities of 100 stems per acre or fewer. <br />Concentration Area Density <br />(Table A- 4) <br />Total average "Concentration Area" woody plant density in BRB -5 was 2,035.6 stems per acre. Big <br />sagebrush was the densest at 1,223.0 stems per acre followed by mountain snowberry with 433.0 stems <br />per acre. Six other species of shrub were present, each with densities of fewer than 220 stems per acre. <br />13 <br />
