<br />BACY.GROUND <br />This study was set up to simulate the aspect, topography, and <br />soils on the majority of the area to be mined on the Colowyo site. <br />The revegetation test plot is located on an 18% north-facing slope <br />. - at an elevation of 7,400 feet. The surface of the study site was <br />prepared by removing the brush, then stripping off the top one-inch <br />of soil to remove roots, rhizomes, and sod. After the stripping <br />operations, the top one-foot of soil was thoroughly mixed by removing <br />the soil from one area of the plot and redistributing it over another. <br />The revegetation plot was fenced with a 9-foot deer fence and a 4-foot <br />rodent fence with 2 feet of the rodent fence buried. <br />Each of the individual studies within the revegetation plot are <br />designed to provide information on techniques of establishing shrubs <br />considering competition and erosion control. The eight studies can <br />be broken down into five major categories: <br />1. Individual species seedings using both native and <br />introduced species. <br />2. Runoff plots.which will provide information on <br />sediment and water yield as affected by seeding <br />management practices. <br />3. Competition studies involving fertility, seeding <br />management practices, and species combinations. <br />4. Shrub transplanting studies. <br />5. Studies involving the establishment of shrubs through <br />reduced herbaceous competition. <br />The term serviceberry as used generally in this report refers <br />to the native serviceberry shruhs on the Colowyo site, .amel.rrrtcltier <br />alnifelia. Serv_iceberry seed or seedlings from other sources are <br />• not necessarily this species. When other common names such as <br />_ bitterbrush, chokecherry, oak, or snowberry are used, they are in <br />reference to Purshia tride~ttata, Prwtus vir~irtiarvz, Quercus galvbf:lzi., <br />3 <br />
