• onion, Eaton thistle, wallflower (Ervsimum asperuml, groundsmoke, showy goldeneye, white- <br />flowered peavine, silver lupine (lsupinus ~genteusl, wild tarragon, and American vetch were <br />also present. Introduced perennial (orbs accounted for 1.7 percent of total vegetation cover. <br />Nearly half of this percentage was provided by alfalfa. Cicer milkvetch and Canada thistle <br />provided the remaining part. Common dandelion was also present. Two native shrubs, mountain <br />snowberry and big sagebrush, were present but did not contribute measurably to total <br />vegetation cover. <br />Total vegetation cover averaged 47.4 percent. Standing dead, litter, bare soil, and rock cover <br />averaged 0.4, 18.2, 31.6, and 2.4 percent, respectively. Species density averaged 26.9 species <br />per 100 sq.m. <br />Biomass production data were not collected in this reclamation area. <br />Two native shrubs, big sagebrush and mountain snowberry were the only shrubs recorded in <br />this reclamation unit (Table 9). Together, they accounted for an average of 36.4 shrubs per <br />acre. <br />Wadge Pasture (Photographs 14 through 17) <br />Cover <br />Introduced perennial forts dominated this reclamation unit with 42.1 percent of total vegetation <br />cover (Table 10). Alfalfa provided more than four-fifths of this cover. Cicer milkvetch, <br />Canada thistle, and common dandelion contributed the balance. Native perennial forts, the most <br />diverse lifeform, contributed 4.5 percent of total vegetation cover. James starwort provided <br />more than half of this percentage. Showy fleabane, wild tarragon, and common Yampa accounted <br />for the remaining fraction of this lifeform's measured total vegetation cover. Other species <br />present included western yarrow, blue flax, nettle-leaf giant hyssop, false dandelion (Aaoseris <br />91a~ca1, big-flowered onion, Eaton thistle, groundsmoke, gumweed, one-slower woodsunflower <br />(Helianthella uniflora), showy goldeneye, white-flowered peavine, wayside gromwell <br />( ith permum ruderale), tailcup lupine, Rocky Mountain penstemon, and death camas. <br />CJ <br />14 <br />
