by alfalfa, the remainder by titer milkvetch (Astragalus titer). Native perennial grasses <br />I • <br />averaged 10% of total vegetation cover. Half this total was composed of sheep fescue (Festuca <br />brachyphylla ssp. coloradensis), and the remaining half was primarily composed of basin wifdrye <br />(Leymus cinereus). Whitetop (Cardaria drabs) was observed in the area. <br />Total vegetation cover was 54.9 percent. Cover by standing dead, litter, bare soil, and rock was <br />2.4, 35.3, 7.1, and 0.3 percents, respectively. <br />PRODUCTION <br />(Table 14) <br />In 2004, Wadge Pasture averaged 2,492.8 pounds per acre or herbaceous production. Alfalfa <br />averaged 308 pounds per acre. <br />WOODY PLANT DENSITY <br />(Table 15) <br />955.1 stems per acre of woody plant were observed in Wadge Pasture in 2004. Of this total, <br />464.6 stems per acre were attributable to snowberry, 292.6 to big sagebrush, and 156.6 to tall <br />threetip sagebrush (Seriphidium tripartitum) seedlings. Utah serviceberry (Amelanchier <br />utahensis) and Douglas rabbitbrush (Chrysothamnus viscidiflorus) were observed at low <br />• densities. <br />Alkali Sagebrush Reference Area <br />(Photographs 21-24) <br />COVER <br />(Table 16) <br />Native shrubs dominated this reference area in 2004 averaging 43.5 percent of total vegetation <br />cover. 7I10ths of this total was due to cover by alkali sagebrush (Seriphidium arbusculum ssp. <br />longilobum). ,Big sagebrush, snowberry, and Douglas rabbitbrush also contributed to the lifeform <br />total. Composing 22 percent of total vegetation cover were several species of native perennial <br />cool season grass. Each occupying approximately 113rd of this total were western wheatgrass <br />and Letterman needlegrass (Achnatherum lettermanir). Twenty percent of total vegetation cover <br />was by native perennial (orbs. Over half this total was composed of arrowleaf balsamroot <br />(Balsamorhiza sagittata), the balance predominantly shared by weedy milkvetch (Astragalus <br />miser var. oblongifolius), one-flower woodsunflower (Helianthella uniflora), and big-flowered onion <br />(Allium macropetalum). Houndstongue was also present in this area. <br />• 10 <br />
