grass, 9 percent Indian ricegrass, 5 percent pine <br />needlegrass, and 5 percent other grasses. Big sagebrush <br />makes up 15 percent of the community, and Douglas <br />rabbitbrush makes up 3 percent • these are the main <br />shrubs. The community is also 5 percent buckwheat, <br />5 percent phlox, 3 percent pussytoes, and 5 percent <br />lupine, gray horsebrush, and other forbs. <br />This site is suitable for grazing livestock. Heavy <br />grazing by cattle causes pine needlegrass, junegrass, <br />and muttongrass to decrease and big sagebrush, Dou -- <br />las rabbitbrush, and forbs to increase. If grazing is <br />severe or prolonged, total production declines sharply. <br />Condition of the range vegetation can be improved <br />by use of pIanned grazing systems and proper grazing <br />practices, but response is slow. Because of the low pre- <br />cipitation, the success of range seeding is questionable. <br />Results of seeding may be good in years of above - <br />average precipitation. Brush management improves <br />the range if it is needed and if there is a sufficient <br />understory of climax plants, <br />The estimated total annual production of air -dry <br />plant material ranges from 400 pounds per acre in poor <br />years to 900 pounds per acre in good years. About <br />300 to 700 pounds per acre is suitable forage for live - <br />stock. <br />• Soils Descriptions: <br />See below <br />7 <br />
