Total average vegetation cover for first hits was 46.8 percent. Allowable all -hit herbaceous vegetation cover <br />was 45.4 percent. Cover by standing dead, litter, bare soil and rock averaged 0.8, 25.4, 26.6 and 0.4 <br />percent, respectively (first hit). Average species density was 25.0 species per 100 sq. m. <br />PRODUCTION <br />(Table A -14) <br />Total herbaceous production in 2011 was 945.7 pounds per acre. Of this, 415.8 pounds were attributable to <br />each native perennial cool season grasses and native perennial forbs. Native annual and biennial forbs <br />contributed 85.7 pounds per acre. Three other lifeforms were present at less than 20 pounds per acre. <br />2012 Phase III BRB -1 <br />(Photographs 134 through 157) <br />COVER <br />(Table B -1) <br />The dominant lifeforms in the BRB -1 in 2012 were introduced perennial forbs, introduced perennial cool <br />season grasses and native perennial cool season grasses with 6.8, 8.7 and 14.3 percent all -hit vegetation <br />cover respectively. Introduced perennial forb cover was composed mostly of alfalfa, introduced perennial <br />cool season grass cover was predominantly composed of orchard grass (Dactylis glomerate) and <br />intermediate wheatgrass and native perennial cool season grasses was composed mostly of western <br />wheatgrass and Rocky Mountain fescue. A total of 72 native plant speciews were encountered during <br />quantitative sampling along with 35 non - native species of which three (Medicago sativa, Astragalus cicer, <br />and Onobrychis viciaefolia) were planted as desirable legumes. Among these non - natives observed in the <br />area were the noxious weeds musk thistle, hound's tongue (0.5 percent cover), whitetop (0.3 percent <br />cover), and Canada thistle (0.2 percent cover). <br />Total average vegetation cover for first -hits was 35.7 percent. Allowable all -hit herbaceous cover was 33.9 <br />percent. Cover by standing dead, litter, bare soil and rock averaged 3.0, 39.9, 20.0 and 1.3 percent, <br />respectively (first hits). Average species density was 26.7 species per 100 sq. m. <br />PRODUCTION <br />(Table B -2) <br />18 <br />
