Seed acquired for the various seed mixes will be of the highest quality possible.

However, all seed mixes are <br /> specified on a PlS basis, ensuring the specified amount of viable seed is being applied. <br /> Sources will be on a regional basis when ever possible, particularly for the native harvest <br /> species. Seed tags for all seed used in a given reclamation year will be p resented in [he <br /> annual reclamation report. <br /> Native species predominate in all mixes, including Seed Mix No. 3 for temporary <br /> reclamation. The following species, by seed mix, are introduced. <br /> Seed Mix No. 1 Orchardgrass <br /> Russian wildrye <br /> Cicer milkvetch <br /> Alfalfa <br /> Seed Mix No. 2 Red top bentgrass <br /> Creeping foxteil <br /> Birdsfoot trefoil <br /> Seed Mix No. 3 Intermediate wheat grass <br /> A lfaLfa <br />The above introduced species have been included in the mixes to enhance the forage utility <br />of the revegetated lands, legume presence in the stand, benefit wildlife habitat, ensure <br />sufficient types of species are present to cover a range of site conditions, and provide <br />adequate vegetation cover on more adverse sites. These species, as cell as all natives in <br />the mixes, are compatible with the plant and animal species of the region and are not <br />poisonous or noxious. The species are desirable and necessary to achieve the approved <br />postmining land use. The introduced species proposed have been developed for, or used in, <br />a variety of agronomic situations in the western U.S. for many years and are well <br />documented in the technical literature. <br />Seeding and Planting Methods. Seeding of the permanent seed mixes will be done the first <br />fall seeding season after topsoil distribution. At the Seneca 11 Nine, seeding has been <br />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 <br />the fall seeding season to provide interim stabilization as necessary. The normal <br />seeding season will run from August 15 to approximately November 1. weather conditions <br />13-25 Revised 01/15/93 <br />
