Seed Mix No.3 Tall wheatgrass • <br />Russian wildrye <br />Alkali grass <br />Alfalfa <br />Seed Mis No.4 Intermediate wheatgrass <br />AlfaiEa <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 covet 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 vaziety of agronomic situations in the western <br />U.S. for many years and aze well documented in the technical literature. <br />Seedine and Planting Methods. Seeding of the permanent seed mixes will be done the fast 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 insulating <br />affects of heavy snow cover. Cover crops may be seeded at any time from late spring to the <br />fall planting season to provide interim stabilization as necessary. Seeding of perennial mixes in <br />areas with cover crops will be timed to avoid direct competition with actively growing cover <br />crop species. Cover crops that may produce seed that would compete with the perennial tttix <br />will be mowed prior to seed maturation. The normal planting season will run from August 15 <br />to approximately November 1. Weather conditions may require earlier termination of the fall <br />planting season. Spring weather conditions severely limit the opportunities for seeding of the <br />permanent mixes. The month of May will be the only consistent period available For spring <br />seeding. All spring seeding activities will be completed by June 15. Any transplanting, <br />interseeding, or reseeding of permanent reclamation would usually be accomplished concurrent <br />with the regular planting season. <br />Seeding will be accomplished by drill seeding, broadcast seeding, of hydroseeding. Drill <br />seeding is the preferred method and will be employed on the majority of reclaimed areas. A • <br />rangeland type drill equipped with two seed boxes will be used for all drill seeding. This type <br />of drill is capable of handling the rough and trashy surface conditions common in re-topsoiied <br />PR-03 <br />34 <br />
