contributed 0.9 percent to total vegetation cover. Thirteen native perennial forbs were observed <br />in the Wadge Pasture area, but together they only contributed 0.6 percent of total vegetation <br />cover. Introduced annual grasses were observed but did not contribute to total vegetation. <br />Total vegetation cover was 65.6 percent. Standing dead, litter, bare soil, and rock cover values <br />were 1.0, 26.0, 7.0, and 0.4 percent respectively. Species density averaged 15.9 species per 100 <br />sq. m. <br />Production (Table 16) <br />Average production for alfalfa was 530.0 pounds per acre in the Wadge Pasture area. Other <br />species contributed 1,807.8 pounds per acre. Total combined production for the Wadge Pastore <br />area was 2,337.5 pounds per acre. <br />Woody Plant Density Data (Table 17) <br />Native shrubs averaged 360.2 stems per acre. Big sagebrush contributed three-fifths of this total. <br />Mountain snowberry contributed nearly three-fifths and mountain serviceberry provided nearly <br />two-fifths of the total. The remaining balance was accounted for by Saskatoon serviceberry, <br />silver sagebrush, rubber rabbitbrush, and Douglas rabbitbrush (Chrysothamnus visciditlorus). <br />Mountain Brush Reference Area <br />(Photographs 25) <br />Cover (Table 8) <br />Native shrubs were the dominant lifeform in this area and contributed 81.4 percent of total <br />vegetation cover. Gambel's oak contributed nearly one-half of this lifeform's total. Saskatoon <br />serviceberry contributed nearly one-third of this total. Mountain snowberry contributed one-eighth <br />of the this total. The remainder of the total was comprised of chokecherry, Wood's rose, common <br />• juniper, big sagebrush, and dogwood (Swida sericea). Native perennial cool season grasses <br />contributed 9.0 percent of total vegetation cover. Agassiz bluegrass accounted for more than <br />two-thirds and Nelson needlegrass (Achnatherum nelsonii) accounted for one-fourth of this <br />lifeform's total. The remainder was comprised of onion grass(Bromelica spectabilis), elk sedge <br />(Carex geyen) and western wheatgrass. Native perennial forbs averaged 5.3 percent of total <br />vegetation cover. Colorado violet (Viola scopulorum) and Richard geranium (Geranium <br />richardsonii) each contributed about one-fourth of this lifeform's total. Horsemint (Monarda <br />fistu/osa var. menthifolia), western yarrow, wild buckweet (Eriogonum umbellatum), wild <br />strawberry (Frasera virginiana ssp. glauca), seemly sweetpea (Lathyrus eucosmus) Fendler <br />meadowrue (Thalictrum fendleri) and American vetch accounted for the balance. Twenty-three <br />other native perennial forbs were observed in the mountain brush reference area but did not <br />contribute to the total. Hound's tongue was the only introduced perennial forb observed in this <br />area and contributed 2.7 percent to total vegetation cover. One fern species, braken fern <br />(Pteridium aquilinum ssp. lanuginosum) was observed in this area and contributed 1.4 percent to <br />total vegetation cover. Native trees contributed 0.2 percent of total vegetation cover. <br />Total vegetation cover was 82.8 percent. Standing dead, Litter and bare soil were 1.0, 11.0, and <br />5.2 percent respectively. Species density was 22.7 species per 100 sq.m. <br />Production (Table 19) <br />Total herbaceous production for all species was 519.3 pounds per acre. No alfalfa was observed <br />in this native reference area. <br />12 <br />
