2012 Sagebrush Reference Area <br />(Photographs 29 through 34) <br />COVER <br />(Table A -9) <br />Native shrubs were the predominant lifeform observed in the Sagebrush Reference Area, contributing <br />24.0 percent all -hit vegetation cover. Of this, mountain snowberry contributed 14.3 percent and big <br />sagebrush contributed 7.4 percent. Native perennial cool season grasses and native perennial f orbs and <br />made strong contributions to all -hit cover, with 15.3 and 11.0 percent, respectively. <br />Also observed in the area in small amounts was the noxious weed hound's tongue (Cynoglossum <br />officinale, 0.1 percent cover). <br />Total average vegetation cover for first hits was 50.2 percent. Allowable all -hit herbaceous vegetation <br />cover was 30.8 percent (Table C -1). Cover by standing dead, litter, bare soil and rock averaged 5.8, <br />36.8, 7.1 and 0.1 percent, respectively (first hit). Average species density was 27.6 species per 100 sq. <br />m. <br />PRODUCTION <br />(Table A -10) <br />Total herbaceous production in 2012 was 444.3 pounds per acre. Of this, 242.7 pounds were native <br />perennial cool season grasses and 176.7 were native perennial f orbs. Five other lifeforms were present <br />at less than 20 pounds per acre. <br />16 <br />
