vegetation cover. Dominant species were Saskatoon snowberry (12.66%) and snowberry <br />(12.07%). Native trees, specifically quaking aspen (Populus tremuloides) accounted for 28.1 <br />• percent of total vegetation cover. Native perennial cool season grasses composed 9.4 percent <br />total vegetation cover. Slender wheatgrass and blue wildrye (Elymus glaucus) were the most <br />common species in this lifeform with 5/10`hs and 4/10'"' of total vegetation cover. Introduced <br />annual and biennial (orbs, introduced perennial (orbs, native annual and biennial (orbs, and <br />introduced perennial grasses each composed less than 2% of total vegetation cover. <br />Total vegetation cover for the area in 2003 was 84.8, with total herbaceous cover of 27.8%. <br />Litter, bare soil, and standing dead comprised 9.9%, 4.4%, and 0.9% of total cover, respectively. <br />HERBACEOUS PRODUCTION (TABLE 8) <br />Total herbaceous production averaged 2,334 pounds per acre. <br />Mountain Brush Extended Reference Area <br />(Photographs 13 through 16) <br />COVER (TABLE 9) <br />Native shrubs comprised 70.1 percent of total vegetation cover in this reference area. Gambel's <br />oak accounted for nearly half and mountain snowberry averaged over one-quarter of this total. <br />Together, Saskatoon serviceberry, chokecherry and big sagebrush accounted for the balance. <br />Native perennial cool season grasses averaged 19.3 percent of total vegetation cover. Agassiz <br />bluegrass (Poa agassizensis) contributed nearly one-half of this total. Elk sedge (Carex geyen) <br />and needle and thread (Hesperostipa comata) were also abundant species in this lifeform. Native <br />perennial forbs contributed 5.6 percent of total vegetation cover. Native annual and biennial forbs <br />accounted for 0.4 percent of total vegetation cover. Introduced annual grasses, introduced <br />annual and biennial forbs, introduced perennial forbs and introduced perennial cool season <br />grasses each accounted for one percent or less of total vegetation cover. <br />Total vegetation cover was 64.8 percent. Standing dead, litter, bare soil, and rock averaged 2.4, <br />21.0, 11.2, and 0.6 percent respectively. Total species density averaged 25.4 species per 100 <br />sq. m. <br />HERBACEOUS PRODUCTION (TABLE 71 <br />Total herbaceous production averaged 500.2 pounds per acre. <br />Sagebrush Extended Reference Area <br />(Photographs 13 through 16) <br />
