species of native plants were encountered during quantitative sampling along with 19 non - natives, among <br />which were the noxious weeds Canada thistle (0.8 percent cover), hound's tongue (0.4 percent cover) and <br />bull thistle. <br />Total average vegetation cover for first hits was 72.3 percent. Allowable all -hit herbaceous vegetation cover <br />was also 48.0 percent. Cover by standing dead, litter, bare soil and rock averaged 2.0, 23.3, 2.5 and 0.0 <br />percent, respectively (first hit). Average species density was 36.7 species per 100 sq. m. <br />PRODUCTION <br />(Table B -6) <br />Total herbaceous production in 2012 was 756.6 pounds per acre. Of this, 517.5 pounds were native <br />perennial forbs, 203.4 were native perennial cool season grasses and 32.1 were introduced perennial cool <br />season grasses. Three other lifeforms were present at less than 2 pounds per acre. <br />2012 Mountain Brush Reference Area <br />(Photographs 164 through 167) <br />COVER <br />(Table B -7) <br />Native shrubs were the predominant lifeform observed in the Mountain Brush Reference Area, contributing <br />52.9 percent all -hit vegetation cover. Of this, Gambel's oak contributed 32.7 percent, mountain snowberry <br />contributed 12.7 percent, Saskatoon serviceberry contributed 3.0 percent and chokecherry contributed 2.7 <br />percent. Native perennial cool season grasses made a strong contribution to all -hit cover, with 21.8 percent. <br />A total of 77 species of native plants were encountered during quantatative sampling along with 14 <br />non - natives, among which was the noxious weed hound's tongue (0.7 percent cover). <br />Total average vegetation cover for first hits was 60.9 percent. Allowable all -hit herbaceous vegetation cover <br />was 26.5 percent. Cover by standing dead, litter, bare soil and rock averaged 3.0, 25.7, 9.7 and 0.7 <br />percent, respectively (first hit). Average species density was 25.9 species per 100 sq. m. <br />PRODUCTION <br />(Table B -8) <br />20 <br />
