percent to vegetation cover, comprised almost entirely of blue wildrye (Elymus glaucus, 7.8 percent) and <br />Agassiz bluegrass (Poa pratensis ssp. agassizensis, 1.5 percent). Ferns contributed 3.0 percent to <br />vegetation cover, and six other lifeforms were present with less than 1.5 percent cover each. Also <br />observed in the area were the B -List noxious weeds hound's tongue (1.4 percent cover) and Canada <br />thistle (1.1 percent cover). <br />Total average all -hit vegetation cover was 146.1 percent. Allowable all -hit herbaceous vegetation cover <br />was 74.3 percent. Cover by standing dead, litter, bare soil and rock averaged 0.6, 12.2, 1.8, and 0.0 <br />percent, respectively (first hit). Average species density was 33.4 species per 100 sq. m. <br />PRODUCTION <br />(Table A-8) <br />Total herbaceous production in 2015 was 915.4 pounds per acre, all of which was allowable herbaceous <br />production. Of this, 713.8 pounds were native perennial forbs, 128.5 pounds were native perennial cool <br />season grasses, and 69.6 pounds were ferns. Three other lifeforms, introduced annual and biennial <br />forbs, introduced perennial forbs, and native annual and biennial (orbs, were present at less than 2 <br />pounds per acre each. <br />2015 Mountain Brush Extended Reference Area <br />(Photographs 53 through 72) <br />COVER <br />(Table A-9) <br />Native shrubs were the predominant lifeform observed in the Mountain Brush ERA, contributing 71.8 <br />percent all -hit vegetation cover. Of this, Gambel's oak contributed 39.4 percent, mountain snowberry <br />contributed 20.6 percent, Saskatoon serviceberry contributed 6.5 percent, and chokecherry contributed <br />4.3 percent. Native perennial cool season grasses and native perennial forbs made strong contributions <br />to all -hit cover, with 30.7 and 22.1 percent, respectively. Native perennial cool season grasses were <br />predominantly comprised of Agasiz bluegrass (16.5 percent) and elk sedge (Carex geyeri, 7.9 percent), <br />while native perennial forbs were comprised of many species, none of which were dominant. Introduced <br />annual and biennial forbs, native annual and biennial forbs, introduced perennial cool season grasses <br />and introduced annual grasses contributed less than 3.0 percent vegetation cover each. Introduced <br />perennial forbs were also present. Also observed in the area were the B -List noxious weed hound's <br />tongue (2.6 percent cover) and common -mullen (present but not in measurable amounts). The C -List <br />noxious weed cheatgrass was present with 0.1 percent cover. <br />18 <br />
