thermal cover in each 46-acre area of influence. The major shrub species transplanted are Gambel's <br /> oak, serviceberry, chokecherry, and snowberry. However, all shrub species will be counted to meet <br /> density requirements since all species provide some measure of forage and/or cover (Table 4.4-14). As <br /> described in Section 3.6.3.5, the seeding of low shrubs between the mature shrub clumps may be done. <br /> The shrub density standard may also be met without the inclusion of shrub clumps by meeting a 550 live <br /> stems per acre threshold. <br /> Further, direct haul of topsoil from the prestrip area to the regraded spoils results in sprouting of native <br /> perennials. Additionally, aerial or interseeding of big sagebrush may be performed to increase winter <br /> forage for wildlife. Thus, a random distribution of various native shrub species can be expected. <br /> Directly hauled topsoil may also be applied to the mature shrub clump areas. Sprouting of shrubs from <br /> freshly removed and replaced topsoil will add to the density of shrub species within clumps and provide <br /> additional cover and forage. If sufficient shrub sprouting can be achieved through the direct haul of top- <br /> soil to meet the 400 shrub stems per acre standard, other forms of shrub establishment, with the excep- <br /> tion of mature shrub clumps, may be curtailed. <br /> A determination of having met the shrub density standard will be based on density transects conducted <br /> the last two years of the 10-year liability period (or in two consecutive years subsequent to the 10-year <br /> liability period) across the reclaimed areas, including shrub re-establishment areas. Direct count belt <br /> transects will be used to obtain an average shrub stem density count on reclaimed lands, A and B range <br /> sites. Actual woody stem sampling methodologies for determining establishment success are discussed <br /> in Section 4.4.1.6. <br /> In shrub clumps, transplanted shrub pads will be inventoried for presence or absence of live woody <br /> plants. A shrub pad will be deemed successfully established if at least 10 live woody stems, from either <br /> original transplants or from resprouted plants, are observed. If less than 10 live woody stems are <br /> observed, a pad will be considered unsuccessful. <br /> From density transects an average stem density count per acre per unit area of reclaimed land will be <br /> calculated. Successful shrub stem density will be calculated by one of two options. Option one would <br /> include shrub clumps and the density standard would be the following. If the actual average shrub stem <br /> density count is > 400 stems per acre and the shrub pad survival within shrub clumps is at least 50%, <br /> successful shrub stem establishment will have been met. The 400 stems per acre standard shall include <br /> the shrub stem benefit derived from stems within the mature shrub clumps. Option two would not include <br /> shrub clumps and would require that the standard to satisfy successful shrub density would be > 550 live <br /> stems per acre. <br /> The narrative in Section 3.6.3.5 describes shrub establishment methods and species to be utilized. <br /> 4-119 <br />
