contribute larger quantities of trash and inert matter. However, all seed mixes are specified on a PLS basis, ensuring the proper amount of viable seed is being applied. • Sources for seed will be on a regional basis whenever possible, particularly for the native harvest species. Seed tags for all seed used in a given reclamation year will be presented in the annual reclamation report. Native species predominate in all mixes, including Seed Mix No. 4 for temporary reclamation. The following species, by seed mix, are introduced. Seed Mix Nos. 1A and 1B Orcha rdgrass Alfalfa Seed Mix No. 2 None Seed Mix No. 3 Alkaligrass Alfalfa Seed Mix No. 4 Alfalfa The above introduced species have been included in the mixes to enhance the forage utility of the revegetated Lends, improve the legume presence in the stand, benefit wildlife habitat, ensure sufficient types of species are present to cover a range of site • conditions, and provide adequate vegetation cover on more adverse sites. These species, as well as all natives in the mixes, are compatible with the plant and animal species of the region and are not poisonous or noxious. The species are desirable and necessary to achieve the approved postmining land use. The introduced species proposed have been developed for, or used in, a variety of agronomic situations in the western U.S. for many years and are well documented in the technical literature. Seeding and Planting Methods. Seeding of the permanent seed mixes will be completed by the first fall seeding season after topsoil distribution. At the nearby Seneca II Mine, seeding has been done as early as late August with no winter kill problems. This is due to the insulating effects of heavy snow cover. Cover crops may be seeded at any time from late spring to the fall seeding season to provide interim stabilization as necessary. The normal seeding season will run from August 15 to approximately November 1. weather conditions may require earlier termination of the fall seeding season. Spring weather conditions severely limit the opportunities for seeding of the permanent mixes. The month of May will be the only consistent period available for spring seeding. All spring seeding activities will be completed by June 7. Any transplanting, interseeding, or reseeding • of permanent reclamation will be accomplished concurrent with the regular planting season. Seeding will be accomplished by drill seeding, broadcast seeding, or hydroseeding. Drill 23 Revised 06/19/95
