• In the older reclamation (Wadge Pasture and Wadge Pasture '91), alfalfa comprised from 28.8 <br />to 30.5 percent of total production. By comparison, the 1985 Wolf Creek, 1988 Wadge and <br />1988 Wolf Creek had 10.4 to 12.9 percent alfalfa, while in the 1985 Wadge, no alfalfa fell in <br />the ten randomly located plots clipped. <br />Shrub Density <br />Shrub density data are presented in Tables 19 through 41, summarized in Table 42, and <br />graphically displayed (for reclaimed areas only) in Figure 3. <br />Highest shrub density in reclaimed areas was observed in the Wadge Pasture area (344 stems <br />per acre), while the lowest was found in the 1990 Wadge and 1990 Wolf Creek areas (28.3 and <br />12.1 stems per acre, respectively). The 1985 Wadge, 1985 Wolf Creek, 1988 Wadge, and <br />1988 Wolf Creek areas varied between 126 and 227 stems per acre. The Wadge Pasture '91 <br />area also fell in this range with 206 stems per acre. <br />The most abundant shrubs in all reclaimed areas were basin big sagebrush, mountain big <br />sagebrush, and mountain snowberry. Shrub reproduction, nearly nonexistent in the 1990 <br />• sampling and somewhat more apparent in 1991, was again relatively scarce in 1992. Most <br />reclaimed areas had at least small amounts of serviceberry, chokecherry, prickly rose or <br />Wood's rose. Douglas rabbitbrush was found in the Wadge Pasture area. <br />Although the density of shrubs in the reference areas was not directly relevant since <br />performance standards are set at 1000 stems per acre, the reference area densities may <br />nonetheless be of some general interest. In the Mountain Brush Reference Area, total stem <br />density was 5892 stems per acre, of which the major contributors were serviceberry, <br />chokecherry, mountain snowberry, and Gambel's oak. In the Sagebrush Reference Area, total <br />stem density was 4889 stems per acre, the most important contributors to which were <br />mountain big sagebrush, basin big sagebrush, Douglas rabbitbrush, and mountain snowberry. <br />Data from Shrub Planting Areas No. 1 through 13 show that there were from 202 to 526 stems <br />per acre surviving as of July 1992. These areas were mostly planted in fall 1991; some of <br />them had previously been planted in tall 1990 and were augmented during the 1991 plantings. <br />• 11 <br />
