2015 Phase 111 BRB-3 <br />(Photographs 1 through 32) <br />COVER <br />(Table A-1) <br />The dominant lifeform in the BRB-3 in 2015 was native perennial cool season grasses with 27.9 percent <br />vegetation cover, followed closely by introduced perennial forbs with 14.2 percent. Native perennial cool <br />season grasses were comprised of many species, of which western wheatgrass (Pascopyrum smithii) <br />contributed the greatest amount to cover with 15.1 percent, followed closely by basin wildrye (Leymus <br />cinereus) which contributed 5.0 percent. The remaining 17 species contributed less than 2.5 percent to <br />cover. Introduced perennial forbs were comprised almost entirely of alfafa (Medicago sativa) with 13.0 <br />percent cover. Introduced perennial cool season grasses, introduced annual and biennial forbs, native <br />perennial (orbs, and native shrubs contributed similar amounts to cover with 5.9, 3.6, 3.3, and 3.3 <br />percent, respectively. Introduced perennial cool season grasses were dominated by Kentucky bluegrass <br />(Poa pratensis ssp. pratensis, 2.1 percent), orchard grass (Dactylis glomerata, 1.8 percent), and <br />intermediate wheatgrass (Thinopyrum intermedium, 1.3 percent). Introduced annual and biennial forbs <br />and native perennial forbs were each comprised of many species with no overwhelming dominate; <br />western yarrow (Achillea millefolium) was the largest contributing species to native perennial forbs with <br />1.4 percent. Native shrubs were comprised primarily of big sagebrush (Artemisia tridentate, 2.4 percent). <br />Introduced annual grasses and Native annual and biennial forbs contributed 2.6 and 2.4 percent to cover, <br />respectively. Native trees and bryophytes were present with less than 1.0 percent cover. Also present in <br />the area were the B -List species hound's tongue (Cynoglossum officinale, 0.5 percent cover), Canada <br />thistle (Cirsium arvense, 1.0 percent cover), and dalmation toadflax (Linaria genistifolia ssp. dalmatica, <br />0.03 percent cover). Bull thistle (Cirsium vulgare) and jointed goatgrass (Aegilops cylindricao were also <br />present. C -List species cheatgrass (Bromus tectorum, 1.1 percent cover) and common mullein <br />(Verbascum thapsus) were also present in the area. <br />Total average all—hit vegetation cover was 63.8 percent. Allowable all -hit herbaceous cover was 54.6 <br />percent. Cover by standing dead, litter, bare soil and rock averaged 0.7, 28.0, 12.5, and 0.9 percent, <br />respectively (first hits). Average species density was 26.8 species per 100 sq. m. <br />PRODUCTION <br />(Table A-2) <br />15 <br />
