• Shrubs contribute over 80 percent relative vegetation cover. <br />Gambel oak is the overwhelming dominant, with 52.8 percent absolute cover. <br />Common shrubs are mountain snowberry (Sympho.eicoapo~ ozeophidu~l with 3.6 <br />percent, common chokecherry (%auau~ vi.e~..iniaaol with 3.1 percent, and squaw- <br />apple (%ezaphy.l.lum .zamo~ia~imuml with 3.1 percent.

See <br />Table 3 for additional minor plant species. <br />Production <br />Total herbaceous production for the Mountain Shrubland affected <br />area averages 14.6 g/2 m2 or only 65.1 Ibs/acre. The heavy cover by tall <br />shrubs severely limits herbaceous production by shading and root competition. <br />Perennial graminoids account for over Halt the production with 8.0 y/2 m2. <br />The major graminoid producers are mutton bluegrass and Indian ricegrass with <br />4.3 and 2.2 g/2 m2, respectively. Perennial ferb production averages <br />6.0 g/2 m2. Annual forb production is low, native annuals produce 0.4 g/2 m2 <br />and introduced annuals produce 0.1 g/2 m2. Broom snakeweed, a subshrub, <br />averages 0.1 g/2 m2. See Table 4.. <br />-g- <br />
