Seed Mix No.i Orchardgrass <br />Alfalfa <br />Seed Mix No.2 Redtop bentgrass <br />Creeping foxtail <br />Birdsfoot trefoil <br />Seed Mix No.3 Tall wheatgrass <br />Russian wild rye <br />Alkali grass <br />Alfalfa <br />Seed Mix No.4 Intermediate wheatgrass <br />Alfalfa <br />The above introduced species have been included in the mixes to enhance the forage utility of <br />the revegetated lands, add legumes to supplement any native legumes present in the stand, <br />benefit wildlife habitat, ensure that sufficient types of species are present to cover a range of <br />site conditions, and provide adequate vegetation cover on more adverse sites. The above <br />introduced species, as well as all natives in the mixes are compatible with the plant and animal <br />species of the region and are not poisonous or noxious. These species are desirable and <br />necessary to the achievement of the approved postmining land use. The introduced species <br />proposed have been developed for, or used in, a variety of agronomic situations in the western <br />U.S. for many years and are well documented in the technical literature. <br />Seeding and Planting Methods Seeding of the permanent seed mixes will be done the first fall <br />planting season after topsoil distribution. At the Seneca II Mine five miles to the east, seeding <br />has been done as early as late August with no winter kill problems. This is due to the <br />insulating affects of heavy snow cover. Cover crops may be seeded at any time from late <br />spring to the fall planting season to provide interim stabilization as necessary. Seeding of <br />perennial mixes in areas with cover crops will be timed to avoid direct competition with <br />actively growing cover crop species. Cover crops that may produce seed that would compete <br />with the perennial mix will be mowed prior to seed maturation. The normal planting season will <br />run from August 15 to approximately November 1. Weather conditions may require earlier <br />termination of the fall planting season. Spring weather conditions severely limit the <br />opportunities for seeding of the permanent mixes. The month of May will be the only <br />consistent period available for spring seeding. All spring seeding activities will be completed by <br />June 1. Any transplanting, interseeding, or reseeding of permanent reclamation would usually <br />be accomplished. <br />28 Revised 7/99 <br />
