var. oblongifolius) (5%), biscuitroot (Lomatium spp.) (4%), arrowleaf balsamroot (Balsamorhiza <br />• sagittata) (3%), hollyleaf clover (Trifolium gymnocarpum) (3%), mule's ear (2%), one flower <br />woodsunflower (Heliantha uniflora) (2%), longleaf phlox (Phlox longifolia) (1 %), two-groove <br />milkvetch (1 %), Pacific aster (Virgulasterascendens) (1%), tailcup lupine (Lupinus caudatus) <br />(0.3%), microseris (Microseris nutans) (0.3%), and lambstongue groundsel (Senecio <br />integerrimus) (0.33%). One percent of total vegetation cover was provided by introduced <br />perennial cool season grasses, specifically smooth brome. Native annual and biennial (orbs and <br />introduced annual and biennial forbs each contributed less than 1 % to total vegetation cover. <br />The former was codominated by bigfruit willowherb and gumweed while prickly lettuce dominated <br />the latter. Introduced annual grasses and introduced perennial forbs were also present in the <br />area in very small amount. <br />Total vegetation cover for the Alkali Sagebrush reference area was 30.1 % while standing dead, <br />litter, bare soil accounted for 5.2%, 35.6%, and 29.1 % respectively of total cover. Species <br />density averaged 24.2 species/100sq.m. <br />Production <br />(Table 15) <br />Total herbaceous production averaged 293 Ibs/acre. Alfalfa was present in scattered and <br />. immeasurable amounts in this reference area in 2002. <br />Mountain Brush Reference Area <br />(Photograph 25, 27, and 28) <br />Cover <br />(Table 16) <br />Native shrubs were the dominant lifeform present in the Mountain Brush reference area, with <br />almost 70% of total vegetation cover. Gambel's oak, Saskatoon serviceberry, and mountain <br />snowberry each accounted for approximately 20% of total vegetation cover, while chokecherry <br />accounted for somewhat less than 4% and big sagebrush composed about 2% of total vegetation <br />cover. Contributing less than 1 % to total vegetation cover were common juniper (Juniperus <br />communis ssp. alpina), prickly rose, Woods' rose, tall threetip sagebrush, prickly currant (Ribes <br />lacustre), and wolf currant (Ribes wolfi~). Five other native shrubs were also present in this area. <br />Native perennial cool season grasses were the next most dominant lifeform (18% of total <br />vegetation cover). Over half of this was Aggasiz bluegrass and one-third was elk sedge (Carex <br />geyen). The remainder was composed of Letterman needlegrass, nodding brome (Bromopsis <br />canadensis), slender wheatgrass, blue wildrye (Elymus glaucus), Nelson needlegrass, <br />• oniongrass, mountain brome, and bluebunch wheatgrass.
