• the Mountain Shrubland vegetation type is only 1.22. This relatively <br />low value is to be expected in this fairly xeric community, and although <br />47 species coniriDufe to total cover, over half of the total cover is <br />accounted for by only four species. low species diversify often occurs <br />in disturbed areas where the native flora has been replaced by a few <br />introduced species. See Table 12. <br />3,2.2 Juniper Mfoodfand Vegetation Type <br />Cover <br />An open Juniper Woodland occurs on moderately steep west and <br />southwest Facing slopes. This vegetation type is visually dominated Dy <br />Utah juniper although shrubs are numerically superior. <br />Total free cover is 14.8 percent, composed primarily of <br />Utah juniper 113.7 percents. Rocky Mountain juniper occurs less frequently <br />and accounts for only 1.1 percent cover. See Table 7. <br />Total shrub and subshrub cover is 28.0 percent. A variety <br />of species contribute fo cover; however, Gambel oak is the dominant <br />species with 17.5 percent cover, Mountain snowberry is a subdominant <br />with 6.2 percent cover. Other common shrubs are Saskatoon 5erviceberry <br />11.5 percent) and mountain mahogany 10.9 percents. Minor shrubs present <br />include big sagebrush, fourwing saltbush, spearleaf buckwheat, and <br />• antelope bifterbrush. <br />Total perennial graminoid cover is only Z.5 percent. Most <br />of this is accounted for Dy Indian ricegrass and quackgrass with 1.0 <br />and 0.7 percent cover, respectively, <br />Total annual graminoid cover, two times the perennial <br />graminoid cover, is 5.2 percent. Cheatgrass brume accounts Ior 5.0 <br />percent cover and the small remainder is Japanese brume. <br />As in the Mountain Shrubland vegetation type, these introduced <br />annuals replace native perennials in areas of disturbance resulting <br />from overgrazing. <br />Total perennial forD cover is 4.4 percent. The most common <br />species are arrowleaf balsamroof Qr.Lu:mu.2hiaa .+a9+llula ll.l percent), <br />prairie sage 10.5 percents, yellow thistle Cixnium uc'haucenlzum f0.5 <br />percents, and mountain pepperweed Lepi~Lium munlonum 10.5 percents, <br />Other species present include glaucous aster, Richardson tansy-mustard <br />Dencuna+nia ntc/+¢adnunii, northern sweetvetch //ecly~¢aum Gu.aeale, showy <br />goldeneye lle.(<umezin mu(li~.(uaa, hoary tansy-aster Machueaonl/seza <br />canencen~, American sweefvelch Vicia ume2icuna, and mules-ear wyefhia. <br />Total annual and biennial forb presence is insignificant of <br />0.7 percent cover.
