beardless bluebunch wheatgrass, Canada bluegrass, Letterman needlegrass (Stioa Iettermanii), <br />Nelson needlegrass, and green needlegrass accounted for the balance. Foxtail barley, sheep <br />fescue, basin wildrye, and big bluegrass were also present. Introduced perennial cool season <br />~ grasses provided 8.0 percent of total vegetation cover. Intermediate wheatgrass accounted for <br />three-fifths of this cover percentage. Smooth brome and orchard grass comprised the balance. <br />Desert wheatgrass, redtop (ggrostis a a), quackgrass, meadow fescue, timothy, and <br />Russian wildrye were also present. Introduced annual grasses averaged 10.3 percent of total <br />~ vegetation cover. Wheat accounted for more than two-fifths of this percentage while cheatgrass <br />~, contributed one-third. Japanese brome and cereale rye (Secale cereale) accounted for the <br />balance and common oats was present. Native shrubs did not contribute to total vegetation cover <br />but two species, big sagebrush and mountain snowberry, were present. <br />i Total vegetation cover averaged 41.6 percent while standing dead, litter, bare soil, and rock <br />cover averaged 1.73, 16.27, 37.07, and 3.33 percent, respectively. SpF:cies density averaged <br />38.3 species per 100 sq. m. <br />• <br />~~ Production <br />Biomass production data were not collected in this reclaimed unit. • <br />Shrub Density <br />The native shrubs; big sagebrush and mountain snowberry, averaged 56.7 individuals per acre <br />(Table 11). <br />Wadge Pasture (Photographs 15 through 18) <br />Cover <br />Introduced perennial (orbs, primarily alfalfa, were the dominant litetonn in this unit with <br />39.0 percent of total vegetation cover (Table 12). Cicer milkvetch contributed just over one- <br />I tenth of this average and Canada thistle was a minor contributor. Whitetop, bindweed <br />(Convolvulus arvensis), butter and eggs, and dandelion were present. Mative perennial (orbs <br />were the most diverse lifeform in this unit but only provided 3.8 percent of total vegetation <br />cover. James starwort contributed one-third of this percentage and American vetch accounted <br />for one-quarter. Western yarrow, prairie onion, showy fleabane, white-flowered peavine, <br />~, common yampa, and varileaf scorpionweed contributed the balance. Blue flax, nettle-leaf giant <br />16 • <br />
