Total average vegetation cover for first hits was 38.7 percent. Allowable all -hit herbaceous vegetation cover <br />was 32.2 percent. Cover by standing dead, litter, bare soil and rock averaged 1.8, 10.7, 37.2 and 11.6 <br />percent, respectively (first hit). Average species density was 29.3 species per 100 sq. m. <br />PRODUCTION <br />(Table A -12) <br />Total herbaceous production in 2011 was 503.2 pounds per acre. Of this, 303.3 pounds were native <br />perennial cool season grasses, 139.2 were native perennial forbs and 51.7 pounds were introduced annual <br />grasses. Two other lifeforms were present at less than 6 pounds per acre. <br />2011 Westem Wheatgrass/ Alkali Sagebrush Reference Area <br />(Photographs 104 through 133) <br />COVER <br />(Table A -13) <br />Native perennial cool season grasses were the predominant lifeform observed in the Western Wheatgrass/ <br />Alkali Sagebrush Reference Area, contributing 19.9 percent all -hit vegetation cover. Of this, western <br />wheatgrass contributed 12.3 percent. Native perennial forbs made a strong contribution to all -hit cover, 17.3 <br />percent, most of this as weedy milkvetch (Astragalus miser var. oblongifolius) and sharp -tip onion (Allium <br />acuminatum) (6.6 and 1.9 percent all hit cover, respectively). Also observed in the area was the noxious <br />weed hound's tongue. <br />Total average vegetation cover for first hits was 46.8 percent. Allowable all -hit herbaceous vegetation cover <br />was 45.4 percent. Cover by standing dead, litter, bare soil and rock averaged 0.8, 25.4, 26.6 and 0.4 <br />percent, respectively (first hit). Average species density was 25.0 species per 100 sq. m. <br />PRODUCTION <br />(Table A -14) <br />Total herbaceous production in 2011 was 945.7 pounds per acre. Of this, 415.8 pounds were attributable to <br />each native perennial cool season grasses and native perennial forbs. Native annual and biennial forbs <br />contributed 85.7 pounds per acre. Three other lifeforms were present at less than 20 pounds per acre. <br />18 <br />
