<br /> <br />The shrub reestablishment standard Eor Trapper Mine un range sites A and B <br />will be a minimum of 400 live stems per acre. Part of this standard will <br />be accomplished through the establishment of mature shrub clumps as des- <br />cribed earlier. As [he clumps are approximately 1,400 feet apart, the <br />clumps will have an area of influence of nearly 46 acres. A minimum of 250 <br />mature shrubs are transplanted in each 1.6 acre shrub clump which will pro- <br />vide hiding and thermal cover in each 46-acre area of influence. The major <br />shrub species transplanted are Gambel's Oak, serviceberry, chokecherry, and <br />snuwberry. However, all shrub species will be counted to meet density <br />requirements since all species provide some measure of forage and/or cover. <br />The remainder of the shrub density standard will be met through other <br />methods. As described in Section 3.6.3.5, the seeding of low shrubs <br />between [he mature shrub clumps is done. Additionally, aerial or inter- <br />aeeding of big sagebrush may be performed to increase winter Forage for <br />wildlife. <br />Further, direct haul of topsoil From the prestrip area to the regraded <br />spoils results in sprouting of native perennials. Thus, a random distribu- <br />tion of various native shrub species can be expected. <br />Directly hauled topsoil may also be applied to the mature shrub clump <br />areas. Sprouting of shrubs from freshly removed and replaced topsoil will <br />add to the density of shrub species within clumps and provide additional <br />cover and forage. <br />A determination of having met the shrub density standard will be based un <br />actual counts of shrub stems within clumps and density transects conducted <br />the Last year of the 10-year liability period. The point-center-quarter ur <br />comparable technique will be used [u obtain an average shrub stem density <br />count on reclaimed lands, A and 8 range sites. Adequacy uE sampling will <br />be based un the same technique as approved in our permit for adequate <br />sample size f.or herbaceous cover and production. However, the technique <br />4-126c <br />
