Sagebrush Extended Reference Area <br />(Photographs 22-25) <br />COVER <br />(Table 11) <br />Native shrubs were most abundant in the Sagebrush Reference Area, making up 37.4% <br />of the total 62% vegetation cover. Within this group, alkali sagebrush and mountain <br />snowbeny were most common, having 19.1 % and 14.9% total cover, respectively. <br />Native perennial forts were the second most common life form (11.7% cover), <br />comprised by numerous species with low percent cover values and lacking dominant <br />species. Weedy milkvetch (Astragalus miser var. oblongifolius), tailcup lupine (Lupinus <br />caudatus), chokecherry lupine (Lupinus prunophilus), and an'owleaf balsamroot <br />(Balsamorhiza sagittata) had the highest percent cover values of the native perennial <br />forts (2.9°k, 2.4%, 1.4%, and 1.2%, respectively). Native perennial cool season grasses <br />were the third most abundant group (10.7% cover). Agassiz bluegrass (Poa <br />agassizensis), western wheatgrass, and slender wheatgrass were the most abundant of <br />this group. <br />U <br />Total average vegetation cover, for first hits, was 55.5%. Herbaceous vascular plant <br />cover was 23.9°~. Standing dead, litter, bare soil, and rock each had 2.8%, 28%, 13.7°~, <br />and 0°~ cover, respectively (first hits), Average species density was 26.3 species/100 <br />sq.m. <br />PRODUCTION <br />(Table 12) <br />No alfalfa was present in our sample. Total average production of all other species was <br />1,547.1 Its/acre. <br />DISCUSSION <br />Climatic Conditions <br />The year preceding sampling in July 2005 included a fall with a very wet September and <br />a winter and spring mostly near average except for June 2005 which was more than <br />twice as wet as average (Figures 6a and 6b). When compared to other years in which <br />• monitoring has occurred back to 1987, both the cumulative 12 months and 6 months <br />total precipitation prior to sampling in 2005 ranked near the center of the nineteen years <br />11 <br />
