The only <br />herbaceous species making substantial individual contributions to cover were elk sedge <br />12.0 percent cover), Agassiz bluegrass (8.3 percent cover), Kentucky bluegrass (1.!i <br />percent cover), western yarrow (1.3 percent cover), horsemint 11 .6 percent cover) and <br />American vetch (1.3 percent cover). Litter comprised 16.8 percent cover, while bare soil <br />was 5.2 percent cover. <br />In the Sagebrush Reference Area, cover was dominated by shrubs, basin and mountain big <br />sagebrush (15.9 percent cover) and mountain snowberry 14.6 percent cover); grasses, <br />sheep fescue (17.0 percent cover) and Agassiz bluegrass (7.8 percent cover); and the forb <br />timber milkvetch 15.1 percent cover). Litter was abundant at 22.4 prarcent cover, and bare <br />soil comprised 5.5 percent cover. <br />Production <br />Production data from the 1990 monitoring studies are presented in Tables 14 through 24. <br />Data are summarized in Table 38, and graphically displayed in Figure 2. <br />Highest herbaceous biomass production was measured on the 1986'Nadge Spring area at • <br />3449.7 pounds per acre, approximately twice as much as the other two 1986 Wadge <br />areas (1986 Wadge Fall, 1429.2 pounds per acre, and 1986 Wadge, 1804.5 pounds per <br />acrel. The 1983 Wadge reclamation was more productive (2436.6 pounds per acre) than <br />any of the 1986 Wadge reclamation, except the Wadge Spring area. Wadge Pasture and <br />Wadge Pasture Comparison areas (2740.7 and 2670.5 pounds per acre, respectively) were <br />both more productive than the other Wadge reclamation except for 1 986 Wadge Spring. <br />1983 Wolf Creek reclamation (2192.8 pounds per acre) was nearly 500 pounds greater <br />than the 1986 Wolf Creek (1701.8 pounds per acre). All reclaimed areas had production <br />greater than than either the Mountain Brush or Sagebrush Reference .Areas, or the Native <br />Study Area. <br />In the 1983 Wadge reclamation, alfalfa comprised 41 percent of total production, <br />compared to nearly 50 percent in the 1986 Wadge Spring area, and as compared to 4 and <br />less than 2 percent in the 1986 Wadge Fall and 1986 Wadge areas, respectively. The <br />1983 Wolf Creek area had 22 percent alfalfa compared to 33 percent. in the 1986 Wolf <br />~ Creek reclamation area. <br /> <br />8 <br />
