Fringed sage, a native subshrub, averaged 163.2 individuals per acre and Greene rabbitbrush <br />averaged 8.9 individuals per acre. <br />1995 Reclamation <br />(Photographs 5 through 8) <br />' Cover (Table 4) <br />Native perennial forbs were the dominant lifeform in this area and provided 46.1 percent of total <br />vegetation cover. The major contributor to this lifeform was western yarrow. Blue flax, Rocky <br />' Mountain penstemon, and two-groove milkvetch also made measurable contributions. Native <br />perennial cool-season grasses contributed 18.0 percent of total vegetation cover. Sheep fescue, <br />and slender wheatgrass (Elymus trachycaulus) each contributed more than one-fifth and <br />thickspike wheatgrass, foxtail barley (Critesion jubatum), and western wheatgrass each <br />' contributed more than one-tenth to this total. Basin wildrye (Leymus cinereus), bluebunch <br />wheatgrass, bottlebrush squirreltail (Elymus longifolius), green needlegrass, Agassiz bluegrass, <br />Canada bluegrass, and Sandberg bluegrass were present in lesser quantities. Introduced <br />' perennial forbs contributed 14.5 percent of total vegetation cover. Alfalfa (Medicago sativa) <br />contributed more than two-thirds of this total. Burnet (Sanguisorba mino~j, cicer milkvetch, and <br />Canada thistle contributed the balance. Introduced annual and biennial forbs contributed 9.5 <br />percent of total vegetation cover. Yellow sweetclover (Melilotus of/icinalis) accounted for nearly <br />' nine-tenths of this total. Bull thistle (Cirsium vulgare) and ffixweed tansymustard (Descurainia <br />Sophia) contributed the balance. Introduced perennial cool season grasses accounted for 6.6 <br />percent of total vegetation cover. Russian wildrye accounted for more than four-fifths of this total. <br />Intermediate wheatgrass, desert wheatgrass, and ryegrass (Lolium perenne) made measurable <br />contributions. The native subshrub, fringed sage, contributed 2.8 percent of total vegetation <br />cover. Big sagebrush accounted for 2.2 percent of total vegetation cover. Rubber rabbitbrush <br />and Douglas rabbitbrush were present but did not contribute to measured cover values. <br />' Introduced annual grasses that included cheatgrass (Anisantha tectorum), Japanese brome <br />(Bromus japonicus), and cereale rye (Secale cereale) contributed 0.3 percent of total vegetation <br />cover. <br />Total vegetation cover was 37~ercent. Standing dead, litter, bare soil, and rock were 1.2, 25.1, <br />36.0, and 0.5 percent respectively. Species density was observed to be 19.1 species per 100 sq. <br />m. <br />' Production (Table 5) <br />Native perennial forbs and native perennial cool season grasses were the dominant lifeforms in <br />' this area where total annual production averaged 1320.4 pounds of herbaceous biomass per <br />acre. Native perennial forbs contributed 30.1 percent (397.9 Ib/acre) of total production. Western <br />yarrow and blue flax accounted for more than nine-tenths of this total. Four other species <br />contributed the balance. Native perennial cool season grasses comprised 23.9 percent (315.8 <br />' Ib/acre) of all production in this area. Foxtail barley and slender wheatgrass contributed <br />approximately one-half and one-fourth respectively. Eight other species accounted for the <br />balance. Introduced perennial cool season grasses accounted for 19.9 percent (262.3 Ib/acre) of <br />' all production. Russian wildrye was the dominant species in this lifeform. Four other species <br />made relatively minor contributions. Eleven and one-half percent of all production was <br />contributed by introduced annual and biennial forbs. More than one-half of this production was <br />derived from yellow sweetclover. The balance was contributed by eight other species. Alfalfa <br />' was the dominant species in the group of introduced perennial forbs and accounted for 8.4 <br />percent (110.6 Ib/acre) of all production. Fringed sage, a native subshrub, and the native shrubs, <br />big sagebrush and Douglas rabbitbrush, accounted for 3.9 (51.7 Ib/acre) and 2.2 percent (28.6 <br />Ib/acre), respectively, of all production. <br />
