4-54 <br />Tables 4.5-245 through 4.5-275, respectively, summarize the <br />• cover, production, shrub, and tree data for the three vegetation <br />types quantitatively described. It should be noted that quan- <br />titative data was collected in two other vegetation types for <br />which only qualitative observations were requested. Greasewood <br />Shrubland had the highest vegetation cover and production while <br />-Shadscale Cheatgrass had the highest shrub density. Herbaceous <br />production was very low in the Shadscale Wildrye and Shadscale <br />Cheatgrass vegetation types but modest in the Greasewood Shrub- <br />land. Production in the Greasewood reference area was over <br />twice as high as the Greasewood affected area primarily because <br />it is in good range condition and hence active species contri- <br />bute much of the biomass. The Greasewood reference area was <br />not comparable to the affected area because of the high production <br />and a slightly higher cover. <br />The composition of the vegetation types in the permit revision <br />area has been greatly affected by past disturbance, most likely <br />• prolonged and intensive grazing by livestock. This has resulted <br />in a decrease in the cover of native grasses and forbs and a <br />corresponding increase in introduced native annual grasses and <br />forbs of a weedy nature. Prohibited and restricted noxious <br />weeds are frequent but there are no threatened or endangered <br />plant species. <br />Cover and production sampling was completed to CMLR statistical <br />adequacy requirements and the maximum number of shrub quadrats <br />were sampled. <br />J <br />
