glomerata) comprised almost all of the total for introduced perennial cool season grasses. The <br />• introduced forbs were comprised of three species with the major contributor, being alfalfa. Native <br />annual and biennial forbs and native perennial forbs each accounted for 6.7 percent of total <br />vegetation cover. Four introduced annual and biennial forbs contributed to total vegetation cover, <br />while only three native perennial forbs contributed to total vegetation cover. Introduced annual <br />grasses contributed 1.7 percent to total vegetation cover while native annual and biennial forbs <br />accounted for 1.1 percent of total vegetation cover. <br />Total vegetation cover was 35.0 percent. Standing dead, litter, bare soil, and rock cover values <br />were 0.8, 36.4, 26.0, and 1.8 percent respectively. Species density averaged 22.5 species per <br />100 sq. m. <br />Herbaceous Production (Table 5) <br />Herbaceous production for alfalfa averaged 144.5 pounds per acre, while for all species other <br />than alfalfa the average was 1855.8 pounds per acre. Total herbaceous production for this <br />reclaimed area averaged 1,998.5 pounds per acre. <br />Woody Plant Density (Table 6) <br />Native shrubs averaged 190.2 individuals per acre. Big sagebrush and mountain snowberry each <br />contributed more than one third of this total. Other contributing species were Gambel's oak, <br />hitterbrush and chokecherry (Padus virginiana ssp. melanocarpa). Total woody plant density for <br />this area averaged 190.2 individuals per acre. <br />1999 Reclaimed Area <br />(Photographs 9 through 12) <br />• Cover (Table 7) <br />Introduced annual and biennial forbs were the most dominant species in this young reclaimed <br />area, averaging 64.5 percent of total vegetation cover. Jim Hill mustard (Sisymbrium altissimum) <br />accounted for almost one-third of this total. Twolobe speedwell and deviYs shoestrings <br />(Polygonum arenastrum) each accounted about for one-fifth of the total. Russian thistle (Sa/sola <br />australis) and prickly lettuce each averaged about one-tenth of the total. Five other species from <br />this lifeform contributed to measurable vegetation cover. Native perennial cool season grasses <br />accounted for 24.8 of total vegetation cover. Mountain brome averaged nearly three-fourths while <br />western wheatgrass provided another one-fifth of this total. Slender wheatgrass contributed <br />nearly one-tenth of this total. Introduced perennial cool season grasses accounted for 5.3 of total <br />vegetation cover. Orchard grass contributed more than three-fourths of the total. Native perennial <br />forbs averaged 3.8 percent of total vegetation cover. Blue flax accounted for nearly all of this <br />total. Native annual and biennial forbs and introduced annual grasses each accounted for 0.8 <br />percent of total vegetation cover. <br />Herbaceous Production (Table 8) <br />Total herbaceous production for all species other than alfalfa averaged 1,582.7 pounds per acre. <br />No alfalfa was observed in this reclamation area. <br />Woody Plant Density (Table 9) <br />Native shrubs averaged 32.4 individuals per acre. Mountain snowberry contributed more than <br />three-fifths of the total. Bitterbrush and chokecherry each accounted for about one-fourth of this <br />total. Total woody plant density for this area averaged 32.4 individuals per acre. <br />Aspen Extended Reference Area <br />(Photographs 13 through 16) <br />Cover (Table 10) <br />
