• perennial forb production was mostly 1 to 2 percent of total production except in the youngest <br /> reclamation. In the 198511986 and 1987 Wolf Creek areas (Areas E and F), and the 1987 <br /> Wadge area (Area H), it was about 5 percent of total production. However, the 1 9851 1986 <br /> Wadge area (Area G) was comparable to the older reclamation at only about 2 percent of total <br /> production. Annual plant growth was a substantial portion of total production only in the <br /> youngest (1987) reclaimed areas (both Wadge and Wolf Creek) and in the 1985/1986 Wadge <br /> area (Area G) where annual forbs and grasses were still abundant. <br /> Shrub Density <br /> Shrub density data are presented in Tables 20 through 28, summarized in Table 19, and <br /> graphically displayed (for reclaimed areas only) in Figure 3. <br /> Highest shrub density in reclaimed areas was observed in the 1977 Wadge areas (Area B, 658 <br /> stems per acre), while the lowest was found in the 1985/1986 Wolf Creek areas (Area F, 78 <br /> stems per acre. The Wadge Pasture (Area D) was also distinctly higher than most areas at 476 <br /> stems per acre. The most abundant shrubs in all reclaimed areas are basin big sagebrush and <br /> • mountain snowberry. Current reproduction of shrubs was by far most sbundant in the Wadge <br /> Pasture (Area D) where 240 stems per acre were classed as seedlings. Besides that area, the <br /> most abundant reproduction was only about 35 stems per acre (1977 Wadge, Area B) and 37 <br /> stems per acre (1987 Wadge, Area H). Most reclaimed areas had at least small amounts of <br /> serviceberry,chokecherry, and prickly rose or Wood's rose. Antelope bitterbrush was present <br /> in very small amounts in the 1985/1986 Wolf Creek and Wadge areas (Areas E and G, <br /> respectively). <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 11,661 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 4371 stems per acre, the most important contributors to which were basin big <br /> sagebrush, Douglas rabbitbrush, and mountain snowberry. <br /> • 11 <br />
