PRODUCTION <br />(Table 17) <br />Total herbaceous production averaged 1,363.3 Ibslacre. Alfalfa was not observed. <br />Mountain Brush Reference Area <br />(Photograph 25, 27&28) <br />COVER <br />(Table 18) <br />Just under 80 percent of total vegetation cover was occupied by native shrubs in this area n <br />2003. Gambels oak occupied 28% total vegetation cover, mountain snowberry accounted for <br />21.51 percent, and Saskatoon serviceberry measured 19.68 percent. In lower abundance were <br />chokecherry, big sagebrush, silversagebrush, and Woods rose. Native perennial cool season <br />grasses occupied 10.5 percent total vegetation cover with elk sedge (5.84%) and Agassiz <br />bluegrass (3.03%) dominating. With a total of 35 species of native perennial forb observed, this <br />lifeform contributed 6.1 percent to total vegetation cover. Only nettle leaf giant hyssop <br />(Agastache urticifolia) accounted for over 1 % of total vegetation cover, while 15 other species <br />were quantitatively observed. Lifeforms present with less than 2 percent total vegetation cover <br />were introduced annual antl biennial forbs, ferns, introduced perennia! cool season grasses, and <br />native annual and biennial forbs. Also present were introduced perennial forbs. <br />PRODUCTION <br />(Table 19) <br />Herbaceous production averaged 1,088.5 Ibs/acre. No alfalfa was present in the Mountain Brush <br />reference area in 2003. <br />Sagebrush Reference Area <br />(Photographs 26, 29, and 30) <br />COVER <br />(Table 20) <br />Native shrubs accounted for 43 percent of total vegetation cover in this reference area in 2003. <br />Dominance in this lifeform was nearly split by big sagebrush (20%) and mountain snowberry <br />(19.47%). Also observed quantitatively were Saskatoon serviceberry, Douglas rabbitbrush, and <br />silver sagebrush. 31.2 percent of total vegetation cover was occupied by native perennial forbs. <br />One-flower woodsunflower was the most common species in this lifeform with 31101hs of the total <br />while weedy milkvetch (Astragalus miser var. oblongifolius) accounted for 2110"'s of the total. <br />12 <br />
