• beardless bluebunch wheatgrass (Pseudoroegneria spicata ssp. inermis), green needlegrass <br />(Stioa viridula), and narrow-leaved cattail (Tvoha anq~tifolial were also present. <br />Introduced perennial forbs, primarily alfalfa (Medicago saliva), contributed 37.6 percent of <br />total vegetation cover. Cicer milkvetch (Astragalus cicer) and Canada thistle (Cirsium <br />arvense) also contributed a small amount to measured total vegetation cover measurements.. <br />Bindweed (Convolvulus arvensis) was also present. Native perennial forbs contributed 0.3 <br />percent of total vegetation cover. All of this cover was provided by hoary aster <br />(Machaeranthera canescensl. Other species present in less than measurable amounts included <br />western yarrow (Achilles lanulosa), blue flax (Adenolinum lewisii), willow-herb (Epilobium <br />ciliatum ssp. glandulosum), groundsmoke (Gavoohvtum diffusum), gumweed (Grindelia <br />squarrosa), Rocky Mountain penstemon (Penstemon strictus), James starwort (Pseudostellaria <br />iamesiana), and curly dock (Rumex crispus). Introduced annual and biennial forbs accounted <br />for 7.2 percent of total vegetation cover. Hound's tongue (Cvnoglossum officinale) provided <br />three-quarters of this percentage. Pinnate tansymustard fDescurainia pinnata) and twolobe <br />speedwell (Pocilla biloba) contributed the balance. Littlepod falseflax (Camelina microcaroa), <br />bull thistle (Cirsium vulgare), prickly lettuce (I_actuca serriola), yellow sweetclover <br />(Melilotus officinale), Jim Hill mustard (Sisymbrium altissimum), pennycress (Thlasoi <br />arvense), and salsify (TragQpoaon dubius) were also present. Linearleaf collomia (Collomia <br />Iinearis), a native annual fort, did not contribute measurably to total vegetation cover but was <br />present. <br />Japanese brome (Bromus~ponlGLS), an introduced annual grass, contributed 1.6 percent of <br />total vegetation cover. Cheatgrass (Anisantha tectorum) was also present. Rubber rabbitbrush <br />(Chrvsothamnus nauseosus), a native shrub, provided 0.3 percent of total vegetation cover. <br />Mountain snowberry (Symphoricarpos rotundifolius) was also present. <br />Total vegetation cover averaged 55.6 percent. Standing dead, litter, bare soil, and rock cover <br />averaged 0.2, 27.4, 8.9, and 7.9 percent, respectively. Species density averaged 9 species per <br />100 sq. m. <br />Biomass production data were not collected in this reclamation unit. <br />• <br />8 <br />
