2016 Phase 11 BRB-3 <br />(Photographs 28 through 62) <br />r`nvFR <br />(Table A-2) <br />Cover data were collected at 35 samples in the BRB-3. Native perennial cool season grasses were the <br />largest contributing lifeform to cover with 21.5 percent. Of which, Western wheatgrass (8.7 percent), <br />thickspike wheatgrass (Elymus lanceolatus ssp. lanceolatus, 5.6 percent), Rocky Mountain fescue (2.9 <br />percent), and basin wildrye (2.0 percent) were the dominant contributing species. Introduced perennial <br />cool season grasses followed closely with 16.4 percent cover. Of which, smooth brome (7.6 percent) and <br />intermediate wheatgrass (Thinopyrum intermedium, 6.5 percent) were the greatest contributing species to <br />cover. Introduced perennial forbs contributed 4.1 percent to cover, of which alfalfa was the greatest <br />contributing species with 2.6 percent cover. Introduced annual and biennial forbs and native perennial <br />forbs contributed similar amounts with 3.3 and 2.0 percent, respectively. Yellow sweetclover (Melilotus <br />officinalis) was the greatest contributing species to introduced annual and biennial forbs with 1.8 percent. <br />Native shrubs, native annual and biennial forbs, introduced annual grasses, and bryophytes contributed <br />less than 2.0 percent to cover each. <br />Also observed in the area were small amounts of the B-List noxious weeds Canada thistle (0.6 percent), <br />whitetop (0.1 percent), field bindweed (Convolvulus arvensis, 0.03 percent), musk thistle (Carduus nutans <br />ssp. macrolepis, 0.03 percent), and bull thistle (0.03 percent). Dalmation toadflax and hound's tongue <br />were also present. Cheatgrass was the only C-List species present in the BRB-3 in 2016. <br />Total average all -hit vegetation cover was 50.9 percent. Allowable all -hit herbaceous cover was 48.2 <br />percent (Table B-1). Cover by standing dead, litter, bare soil and rock averaged 0.1, 41.1, 6.9, and 3.1 <br />percent, respectively (first hits). Average species density was 20.3 species per 100 m2. <br />2016 Haul Road Reference Area <br />(Photographs 63 through 77) <br />r`nvFR <br />(Table A-3) <br />Cover data were collected at 15 samples in the Haul Road Reference Area. Introduced perennial cool <br />season grasses were the dominant contributing lifeform with 19.9 percent to cover. Of which, smooth <br />brome (15.0 percent) and Timothy (4.4 percent) were the greatest contributing species. Native shrubs <br />12 <br />
