• PECOCO Pasture Reclaimed Area <br />(Photographs 17-20) <br />Cover (Table 10) <br />Introduced perennial cool season grasses contributed 61.8 percent of total vegetation cover. <br />Intermediate wheatgrass was the main contributor and accounted for nine-tenths of this lifeform's <br />total. Smooth brome, hard sheep fescue, and Russian wild rye (Pasthyrostachys juncea) <br />comprised the balance. Introduced perennial (orbs accounted for 16.2 percent of total vegetation <br />cover. Cicer milkvetch provided three-fifths of this total. Alfalfa and Canada thistle accounted,for <br />one-third and one-tenth of the total respectively. Native perennial cool season grasses <br />contributed 8.8 percent of total vegetation cover. Two-fifths of this total was contributed by basin <br />wildrye. Western wheatgrass accounted for one-third of the total while thickspike wheatgrass <br />contributed one-fifth. The remaining one-tenth was comprised of fescue. Introduced annual and <br />biennial (orbs contributed 8.1 percent of total vegetation cover. Yellow sweet clover was the main <br />contributor and accounted for more than half of this lifeform's total: Twolobe speedwell <br />accounted for one-fifth of the total. The remainder of the total was comprised of hound's tongue, <br />pennycress, and salsify. Gumweed (Grindella squarrosa) a native annual and biennial forb, <br />contributed all of 2.2 percent of this lifeforms total vegetation cover. Sig sagebrush, a native <br />shrub also contributed 2.2 percent of total vegetation cover. Introduced annual grasses <br />contributed 0.7 percent to total vegetation cover. <br />Total vegetation cover was 27.2 percent. Standing dead, litter, bare soil, and rock cover values <br />were 3.0, 50.8, 18.2 and 0.8 percent respectively. Species density averaged 18.1 species per <br />100 sq. m. <br />Production (Table 13) <br />Alfalfa contributed 121.3 pounds per acre in the PECOCO pasture reclamation area. Other <br />species contributed 1,522.1 pounds per acre. Herbaceous production for all species averaged <br />1643.4 pounds per acre. <br />Woody Plant Density Data (Table 13) <br />Native shrubs averaged 214.5 stems per acre. The main contributor to this total was mountain <br />snowberry that averaged more than three-fifths. Big sagebrush contributed more than one-fourth <br />of the total. Wood's rose provided the rest of the total. <br />Wadge Pasture Reclaimed Area <br />(Photographs 21-24) <br />Cover (Table 15) <br />Introduced perennial cool season grasses provided 51.0 percent of total vegetation cover. The <br />main contributor was intermediate wheatgrass which accounted for nearly two-thirds of this <br />lifeform's total. Smooth brome accounted for one third, while hard sheep fescue contributed the <br />balance. Introduced perennial forbs contributed 34.7 percent of total vegetation cover. Alfalfa <br />was the main contributor and accounted for nearly two-thirds of total vegetation cover. Cicer <br />milkvetch accounted for one-third of this lifeform's total. Introduced annual and biennial forbs <br />averaged 5.2 percent of total vegetation cover. Jim Hill mustard, pennycress, and twolobe <br />speedwell were the main contributors and each averaged about one-third of this lifeform's total. <br />A minute amount of salsify also contributed to the total. Native perennial cool season grasses <br />. accounted for 4.4 percent of total vegetation cover. Basin wildrye was the main contributor. <br />Magor contributors included fescue and Agassiz bluegrass. Big sagebrush, a native shrub, <br />contributed all of 3.2 percent to total vegetation cover.
