otherwise stated, all cover values are for absolute first -hit data only. Percentages are rounded to one <br />decimal place to facilitate discussion of the results. <br />2010 Phase III BRB PSCM -1 <br />(Photographs 1 through 8) <br />COVER <br />(Table A -1) <br />Introduced perennial cool season grasses, introduced perennial forbs and native perennial cool season <br />grasses were the predominant lifeforms observed in the BRB PSCM -1 in 2010, contributing on average <br />36.7, 7.3 and 6.5 percent first -hit vegetation cover respectively. Native shrubs, introduced annual and <br />biennial forbs, and native perennial forbs contributed 3.8, 2.1, and 1.4 percent first -hit cover, respectively. <br />Introduced perennial cool season grass cover was composed mostly of intermediate wheatgrass <br />(Thinopyrum intermedium) and smooth brome (Bromopsis inermis). Native perennial cool season grass <br />cover was predominantly composed of basin wildrye (Leymus cinereus), sheep fescue (Festuca ovina). <br />Introduced perennial forb cover total was composed mostly of alfalfa (Medicago sativa). Also observed in <br />the area were the noxious weeds hound's tongue (Cynoglossum officinale), whitetop (Cardaria draba), <br />and Canada thistle (Breea arvense). <br />Total average vegetation cover for first -hits was 58.8 percent. Allowable first -hit herbaceous cover was <br />54.9 percent. Cover by standing dead, litter, bare soil and rock averaged 0.9, 31.5, 8.3 and 0.5 percent, <br />respectively. Average species density was 19.9 species per 100 sq. m. <br />PRODUCTION <br />(Table A -2) <br />Total herbaceous production in BRB PSCM -1 in 2010 was 1,973.5 pounds per acre. Of this, 1,602.4 <br />pounds were introduced perennial cool season grasses, 214.1 were introduced perennial forbs, and <br />114.2 were native perennial cool season grasses. Four other lifeforms were present, each less than 20 <br />pounds per acre. <br />12 <br />
