• Cicer milkvetch was nowhere more than 1 to 2 percent of total biomass production, except in the 1983 Wadge, Wadge Pasture, and Wadge Pasture Comparison areas, where it varied between 5 and 6:5 percent. Shrub Density Shrub density data are presented in Tables 25 through 37, summarized in Table 38, and graphically displayed (for reclaimed areas only) in Figure 3. Highest shrub density in reclaimed areas was observed in the 1983 Wolf Creek area (524.5 stems per acrel, while the lowest was found in the 1983 Wadge and 1988 Wadge areas (132.7 and 135.6 stems per acre, respectivelyi. The Wadge Pasture was relatively high at 407.9 stems per acre, as was the Wadge Pasture Comparison area at 403.9 stems per acre. Within the single year of 1986 in reclamation on Wadge areas, shrub density varied from 156.5 stems per acre in the Wadge Spring area, to 192.2 stems per acre in the Wadge Fall area, on to 317.7 stems per acre in the larger Wadge area. The 1988 Wolf Creek area, at 333.9 stems per acre, while not as high as the 1983 Wolf Creek area, was still high for an area so young. • The most abundant shrubs in all reclaimed areas were basin big sagebrush, mountain big ~, sagebrush, and mountain snowberry. ~ Shrub reproduction was nearly non-existent in the 1990 sampling, being observed only very scantly in the Wadge Pasture area. Most reclaimed areas had at least small amounts of serviceberry, chokecherry, and prickly rose or Wood's rose. Antelope bitterbrush was present in very small amounts in the 1983 Wolf Creek and Wadge areas. Douglas rabbitbrush was found in the 1983 Wolf Creek, 1986 Wadge, Wadge Pasture, and Wadge Pasture Comparison areas. In the Wadge Pasture area, Rocky Mountain juniper and rubber rabbitbrush were also found in very small amounts. Although the density of shrubs in the reference areas was not directly relevant since performance standards are set at 1000 stems per acre, the reference area densities may nonetheless be of some general interest. In the Mountain Brush Reference Area, total stem density was 6614.7 stems per acre, of which the major contributors were serviceberry, chokecherry, mountain snowberry, and Gambel's oak. In the Sagebrush Reference Area, total stem density was 7445.6 stems per acre, the most important -~ • contributors to which were mountain big sagebrush, Douglas rabbitbrush, and mountain snowberry. In the Native Study Area, the total stem density was 9153.2 stems per acre, 9
