COVER (TABLE 8) <br />Native shrubs were dominant in this area and provided 44.0 percent of total vegetation cover. Big <br />• sagebrush averaged more than one-half of this total. Mountain snowberry contributed two-fifths <br />of the total. Saskatoon serviceberry, Douglas rabbitbrush (Chrysothamnus viscidiflorus) and <br />Gambel's oak accounted for the balance. Native perennial cool season grasses accounted for <br />40.4 percent of total vegetation cover. Agassiz bluegrass comprised nearly one-half of this total. <br />Native perennial (orbs contributed 10.4 percent of total vegetation cover. Together, timber <br />milkvetch (Astragalus miservar oblongifolius), chokecherry lupine (Lupinus prunophilus), <br />oneflower wood sunflower (Helianthella uniflora) and James starwort (Pseudostellaria jamesiana) <br />accounted for more than one-half of the total. A total of 28 species of native perennial forbs were <br />encountered during sampling in this area. Introduced annual and biennial forbs accounted for 2.6 <br />percent of total vegetation cover. Introduced annual grasses accounted for 0.9 percent. <br />Introduced perennial forbs contributed 0.7 percent while introduced perennial cool season <br />grasses accounted for 0.5, moss accounted for 0.3 and native annual and biennial forbs <br />accounted for 0.2 percent of total vegetation cover. <br />Total vegetation cover was 52.2 percent. Standing dead, litter, bare soil, and rock cover values <br />were 8.1, 22.6, 16.8 and 0.3 percent, respectively. Total species density averaged 25.5 species <br />per 100 sq. m. <br />. HERBACEOUS PRODUCTION (TABLE 9) <br />Total herbaceous production was 389.5 pounds per acre. <br />DISCUSSION <br />Climatic Conditions <br />The dry growing season of 2002 was followed by anear-average fall 2002 and a generally above- <br />average spring 2003 (Figures 6a and 6b). Although June and especially July were below <br />average, the average far the 12 months preceding late July sampling was slightly above average <br />(Figures 7a and 7b). Considering the previous six-months only (Figures 8a and Sb) the 2003 <br />figures are quite noticeably above average with the effects of the wet spring weighing heavily. <br />From a perspective of the previous four months only (Figures 9a and 9b) the effects of the dry <br />early summer brought the 2003 values down to average. As regards heat from January through <br />June, the year was very near average (Figure 10). <br />
