It appears that the reduction Sn seeding rates for introduced <br />• perennial grasses has enabled a better establishment of the native <br />species. Total vegetation cover was 35.8 percent, and bare soil <br />cover was 8.3 percent. Species density was 11.5 species per square <br />meter which is greater than values for areas seeded prior to 1981. <br />Total production for areas seeded in 1981 was 266.8 g/m2 (Table <br />30). Alfalfa accounted for 56.1 percent of the total production. <br />Introduced perennial grasses accounted for 22.6 percent and native <br />perennial grasses accounted for 16.2 percent. Of Che native <br />perennial grasses, slender wheatgrass (Agropyron trachycauZum) had <br />the highest mean production. Total production was more than twice <br />the herbaceous production of the native reference areas. <br />Total shrub density in the 1981 areas was 1140 shrubs per <br />• hectare (461 shrubs per acre). Mountain snowberry was the major <br />shrub species followed by big sagebrush. In all, six shrub species <br />were encountered in the shrub transects (Table 31). <br />Areas Seeded in 1982. The areas seeded in 1982 (Figure 8) were <br />seeded with the mix listed in Table 32 and was planted with the <br />shrubs listed in Table 33. The mix is the same as that used in 1981 <br />except that there is no record of additional fortis being planted. Of <br />all the herbaceous species included in the mix, only streambank <br />wheatgrass was not observed on the reclaimed areas. Of the tree and <br />shrub species that were planted, chokecherry (Prunes virgtiniana), <br />Rocky Mountain juniper (Juniperus scopulorum), and ponderosa pine <br />(Pines ponderosa) were the only species that were observed. In all, <br />94 species were observed growing in the areas seeded in 1982 (Table <br />. 34). This was the highest number of species observed in any of the <br />71 <br />
