• 1995 Reclaimed Area <br />(Photographs 1 through 4) <br />Cover (Table 1) <br />Native perennial cool season grasses were the dominant species in this area and provided 48.1 <br />percent of total vegetation cover. Agassiz bluegrass (Poo agassizensis) contributed nearly one- <br />forth of this lifeform's cover, Western wheatgrass (Pascopyrum smithii) and fescue (Festuca <br />saximontana) each contributed about one-fifth of the total. Minor contributors included mountain <br />brome (Ceratochloa carinata), basin wildrye (Basin wildrye), Canada bluegrass (Poo compressa), <br />Sandburg bluegrass (Poo secunda) and slender wheatgrass (Elymus trachycaulus). Introduced <br />annual and biennial forbs contributed 13.4 percent to total vegetation cover. Two-lobe. speedwell <br />(Pocilla bi/oba) was the most abundant species in this lifeform and contributed nearly two-thirds of <br />this lifeform's cover. Minor contributors included salsify (Tragopogon dubius ssp. major), bull <br />thistle (Cirsium vulgate), Jim Hill mustard (Sisymbrium altissimum) and pennycress (Thlaspi <br />arvense). Introduced perennial cool season grasses contributed 12.8 percent of total vegetation <br />cover. Orchard grass (Dactylis glomerata), hard sheep fescue (Festuca ovina var. duriuscula), <br />and intermediate wheatgrass (Thinopyrum intermedium) were the major contributors and each <br />species contributed nearly one-third of this lifeform's total cover. Introduced perennial forbs <br />accounted for 12.3 percent of total vegetation cover. Alfalfa (Medicago sativa) was the main <br />contributor and accounted for three-fifths of this lifeform's total. Cicer milkvetch (Astragalus cicer) <br />was the lesser contributor and provided the other two-fifths total cover. Native perennial forbs <br />contributed 10.7 percent of total vegetation cover. Blue Flax (Adenolinum lewisii) and two-groove <br />milkvetch (Astragalus bisulcatus) each contributed two-fifths of this total. Minor contributors <br />included western yarrow (Achilles lanulosa) and Colorado penstemon (Penstemon strictus). <br />Introduced annual grasses contributed 2.7 percent to vegetation cover. Japanese brome <br />(Bromus japonicus) was the major annual grass present and accounted for nearly all of this <br />• lifeform's contribution. <br />Total vegetation cover was 37.4 percent. Standing dead, litter, bare soil, and rock cover values <br />were 0.6, 40.2, 20.6, and 1.2 percent, respectively. Species density averaged 24.2 species per <br />100 sq. m. <br />Herbaceous Production (Table 2) <br />Total herbaceous production for all species other than alfalfa averaged 2,132 pounds per acre. <br />Alfalfa contributed 173.1 pounds per acre, while all other species provided the remaining 1,959 <br />pounds per acre. <br />Woody Plant Density (Table 3) <br />Native shrubs averaged 97.1 individuals per acre. Wood's rose (Rosa woodsii), big sagebrush <br />(Seriphidium tridentatum) and bitterbrush (Purshia trider)tate) each contributed nearly one-third of <br />this total. <br />1997 Reclaimed Area <br />(Photographs 5 through 8) <br />Cover (Table 4) <br />Native perennial cool season grasses averaged 40.6 percent of total vegetation cover for this <br />reclaimed area. Rocky Mountain fescue accounted for more than one-fourth and Mountain brome <br />averaged one-fifth of this total. Western wheatgrass averaged about one-eighth of this total. <br />Agassiz bluegrass, slender wheatgrass, and basin wildrye were also major contributors. Minor <br />contributors included basin wildrye (Leymus cinereus), Canada bluegrass (Poo compressa), <br />(Elymus lanceolatus fm. dasystachya), Rocky Mountain fescue (Festuca saximontana), and <br />Sandberg bluegrass (Poo secunda). Introduced perennial cool season grasses and introduced <br />perennial forbs each averaged 21.7 percent of total vegetation cover. Orchard grass (Dactylis <br />
