• 1994 Reclaimed Area <br />(Photographs 1-4) <br />Cover (Table 1) <br />Introduced perennial (orbs averaged 53.0 percent of the total vegetation cover. This lifeform was <br />comprised mainly of alfalfa (Medicago sativa) which contributed two-thirds of the total. Cicer <br />milkvetch (Astragalus cicer) contributed nearly one-fifth and Canada thistle (Breea arvensis) <br />contributed the balance. Introduced perennial cool season grasses averaged 24.2 percent of the <br />total vegetation cover. More than half of this was contributed by intermediate wheatgrass <br />(Thinopyrum intermedium). Orchard grass (Dactylis glomerata) contributed one-sixth of this <br />lifeform's total. Minor contributors were smooth brome (Bromopsis inermis), hard sheep fescue <br />(Festuca ovina var. duriuscula), and timothy (Phleum pratense). Native perennial cool season <br />grasses accounted for 13.0 percent of the total vegetation cover. More than two-fifths of this was <br />contributed by Agassiz bluegrass (Poo agassizensis). Giant wildrye aka basin wildrye, (Leymus <br />cinereus) averaged nearly one-fifth of this lifeform's total. Other minor contributors were fescue <br />(Festuca saximontana), Sandburg bluegrass (Poo secunda), slender wheatgrass (Elymus <br />trachycaulus) and western wheatgrass (Pascopyrum smithir). Introduced annual and biennial <br />forbs averaged 3.9 percent of the total with two minor contributors: yellow sweetclover (Melilotus <br />officinalis) and Jim Hill mustard (Sisymbrium altissimum). Minor contributors include hound's <br />tongue (Cynoglossum officinale), twolobe speedwell (Pocilla biloba) and satisfy (Tragopogon <br />dubius ssp. major). Native perennial forbs accounted for 3.0 percent of the total vegetation cover. <br />Blue flax (Adenolinum lewisii) and Rocky Mountain penstemon {Penstemon strictus), together, <br />contributed three-fifths of the total. Three other species contributed to the total. Native annual <br />and biennial forbs and introduced annual grasses each contributed 1.2 percent of total vegetation <br />cover. Moss accounted for 0.3 percent of total vegetation cover. <br />• Total vegetation cover was 51.5 percent. Standing dead, litter, bare soil, and rock cover values <br />were 1.67, 32.83, 11.17 and 2.83 percent respectively. Species density averaged 15.9 species <br />per 100 sq. m. <br />Production (Table 2) <br />Herbaceous production for alfalfa averaged 1,247.3 pounds per acre. Herbaceous production for <br />alf other species averaged 1,250.9 pounds per acre. Total herbaceous production averaged <br />2,498.1 pounds per acre. <br />Woody Plant Density (Table 3) <br />Total woody plant density averaged 56.7 individuals per acre. Native shrubs accounted for 52.6 <br />percent of total density. Chokecherry (Padus virginiana ssp. Melanocarpa) and Big sagebrush <br />each accounted for nearly two-fifths. Saskatoon serviceberry (Amelanchier alnifolia) accounted <br />for one-sixth while silver sagebrush (Seriphidium canum) provided the balance. Quaking aspen <br />(Populus tremuloides) contributed 4.0 trees per acre. <br />1997 Reclaimed Area <br />(Photographs 5-8) <br />Cover (Table 4) <br />Native perennial cool season grasses comprised 27.4 of the total vegetation cover. Western <br />wheatgrass comprised almost one-third of this lifeform's cover. Green needlegrass (Nassella <br />viridula) and basin wildrye (Leymus cinereus) each contributed about one-ninth of this lifeform's <br />. total. Slender wheatgrass and mountain brome (Ceratochloa carinata) together averaged nearly <br />one-fifth. Minor contributors were Nelson needlegrass (Achnatherum nelsoni~), thickspike <br />
