HERBACEOUS PRODUCTION (TABLE 51 <br />. On average, there were 1284.8 pounds per acre of herbaceous production in this area in 2004. <br />Mountain Brush Extended Reference Area <br />(Photographs 13 through 16) <br />COVER (TABLE 6) <br />Native shrubs composed 67% of total vegetation cover in-this area in 2004. Gambels oak <br />(Quercus gambelii) was by far the dominant species, composing just over half of the total, while <br />snowberry occupied just under 1/3rtl_of the total. Chokecherry, while occupying only 1/0`" of the <br />lifeform total, composed 7% of total vegetation cover. Native perennial cool season grasses and <br />graminoids constituted 18% of total vegetation cover. One-third of this total was due to cover by <br />Agassiz bluegrass (Poa agassizensis) and'/, was attributable to elk sedge (Carex geyen). <br />Eleven percent of total vegetation cover consisted of native perennial (orbs. Of the 38 species <br />observed, James starwort (Pseudostellaria jamesiana) dominated with 2/10`"° of the lifeform total. <br />In lower abundance were tailcup lupine (Lupinus caudatus), northern bedstraw (Galium <br />septentrionale), and mountain harebells. Houndstongue was also observed in the area. <br />Total vegetation cover was 67.8%. Standing dead, litter, bare soil, and rock comprised the <br />balance with 2.3, 20.8, 8, and1.5 percent of total cover, respectively. Species density was 31.3 <br />• species per 100 sq.m. <br />HERBACEOUS PRODUCTION (TABLE 7) <br />Total herbaceous production averaged 572.8 pounds per acre. <br />Sagebrush Extended Reference Area <br />(Photographs 13 through 16) <br />COVER (TABLE 8) <br />Native shrubs were dominant in this area and provided 63 percent of total vegetation cover. <br />snowberry averaged more than one-half of this total. Big sagebrush averaged 1/3 of the lifeform <br />total. Douglas rabbitbrush (Chrysothamnus viscidiflorus), Saskatoon serviceberry, Gambels oak, <br />and wolf currant (Ribes wolfii) all were observed in low densities. Sixteen percent of total <br />vegetation cover was due to native perennial cool season grasses. Approximately, one-fifth of <br />this total was attributable to Agassiz bluegrass, Montana wheatgrass (Elymus lanceo/atus fm. <br />albicans), and slender wheatgrass. Native perennial fortis amounted to 15% of total vegetation <br />cover. Just under 1l3 of this total was cover by milkvetch (Astragalus laxmani~) and 1/5`" was due <br />to tailcup lupine. Houndstongue was observed in the area. <br />r~ <br />U <br />
