operations and this type of equipment is able to handle the rough field conditions left by the • <br />scraper fleet replacing topsoil. This offsets the need for seedbed preparation. <br />Beginning June 2003 all backfdled spoils will be graded to create irregular topographic <br />undulations. In addition, on reclaimed areas where over-all slope is greater than 25%, replaced <br />soils on slopes steeper than 25% will be pockmarked with dozer dips or track-hoe humps. <br />Steeper slopes will be drill seeded or broadcast seeded as conditions indicate. <br />Seedbed preparation by tillage will be considered in the following situations. In areas where <br />excessive surface compaction has occurred during topsoil replacement, of in compacted non- <br />topsoiled temporary reclamation, offset disking on the contour will be used. In addition, areas <br />with excessive weeds of undesirable vegetation growth map be controlled by mechanical tillage <br />using offset disking on the contour. In shrub establishment areas, competing herbaceous <br />vegetation may be controlled or eliminated by contour disking operations prior to shrub <br />seeding or planting. <br />Controlling weeds or other competing vegetation in aeeas to be seeded of planted may also be carried <br />out through the use of chemical herbiades. • <br />Seed Mixes and Platiting_Lists Four seed mines have been developed for permanent revegetation of <br />the II-W and II-W South permit aeeas and the Tie-Across Haul Road. In addition, a min of small <br />grains for use as a covet crop and a mix of native shrubs speces to be sown alone to generate shrub <br />islands Gave been developed. Also included here aze lists of tree and shrub speces to be used in <br />direct nursery stock planting aeeas again intended to establish shrub islands. <br />Initial considerations in the development of the permanent mixes and seedling (nursery stock) <br />lists included the anticipated reclaimed azea site conditions and the desired revegetation <br />communities. Specific goals which factored into the permanent seed nuxes and seedling lists <br />included rapid and tong-term surface stabilization, ease of establishment, maximum use of <br />native species, adequate species diversity, high levels of utility for livestock and wildlife, good <br />forage production potential, compatibility with naturally regenerating native species present in <br />replaced topsoil, and the ability to be self-sustaining or compliment successional processes in <br />[he reclaimed plant communities. Attainment of these goals, in turq facilitates achievement of <br />the postmining Sand uses. • <br />TR-50 <br />12 <br />Revised 11!04 <br />
