mechanically remove mature aspen trees Erom these azeas, leaving coot clones in _glace which will <br />. sucker sprout into numerous saplings. Following removal of the mature trees, the aspen fawn areas <br />will be fenced to exclude browsing by deer/elk. <br />If the test plot experiments prove successful, then SCC will attempt reestablishment of aspen in the <br />azeas shown on Exhibit 22-1, Postmnring Revegetation Map. If~the experiments prove unsuccessful, <br />Planting List 1 will be used to complete revegetation in the three proposed aspen planting sites. <br />SCC will employ the "Mother Plant" approach for reestablishing tafl shrub speces (ie., seroiceberry <br />and Gambel oak -Planting List 1). Aspects of the tall shrub reestablishment plan will include: <br />• Approximate topsoil replacement thickness within designated planting azeas will be in <br />accordance with the plan depicted on Exhibit 21-1. <br />• Topsoil on the reestablishment azea will be roughened with excavator pockmazks. <br />• 4 to 5 native tall shrub individuals (mostly serviceberry) will be transplanted per acre. 4 x <br />Oft weed control fabric will be installed around each tree. <br />• 10-inch tubelings of chokecherry and servicebetry will be planted on Oft. centers azound <br />• and throughout the native tall shmbs. <br />• The sia Planting List 1 and the three Aspen planting sites will be fenced to exclude <br />browsing animals. <br />• Strategically located snowfencing will be constructed around the planting azea to increase <br />moisture retention <br />• Supplemental iuigation for the tall shmb mother plants will be provided at the time of <br />planting and after that only when soil moisture is low (typically August and September). <br />The sites will be flood irrigated with a water truck using gated pipes and furrows. <br />Supplemental irrigation will be maintained for two years after initial planting. <br />The following shrub and tree planting fists include a selection of trees and shrubs for specific <br />planting azeas or sites. The planted species will provide a basis for the eventual reestablishment <br />of woody plant communities, restore habitat, and enhance plant community diversity, pattern, <br />and structure. The plantings are not intended to restore woody plant communities on a large <br />scale basis in the mine affected areas. However, the species selected for the vazious planting <br />areas (Table 22-7, Shrub and Tree Planting Lists 1-6) are native to the azea or region and will <br />• be able to spread and colonize new areas over time. <br />MR-56 <br />27 <br />Revised 09/04 <br />
