• utilized on live handled topsoil areas where any unnecessary surface manipulation could Gotentially damage native plant propagules contained in the soils. In areas where available topsoil allows increased topsoil replacement thicknesses, topsoil materials will be chisel plowed in addition to previous ripping of surface materials. Chisel plowing may be followed if necessary by disking and harrowing in order to break-up the sail to produce a suitable seedbed. Seeding. Soecies and .mounts EFCI will use several seed mixtures for vegetative establishment on both the mine and loadout areas. The species selected for inclusion in the specific reclamation seed mixtures are predominately native species which have proven effective in re-establishing and adapting to specific conditions at the Southfield site. Considerations involved in selecting species for inclusion in the revegetation seed mixtures included: natural occurrence on the site as documented by baseline vegetation data, ease of establishment, adaptability, value as browse for domestic livestock and wildlife, drought tolerance, and the contribution to vegetative diversity. • The permanent seed mixture as shown on Table 33, Proposed Permanent and Cover Crop Seed Mixtures and Seeding Rates, consists primarily of native grasses with some forb and shrub species. The permanent seed mixture has been developed to provide an effective self-sustaining vegetative cover which will minimize erosion, provide suitable browse for domestic livestock and wildlife species, and include sufficient diversity to ensure the long-term stability of the resulting vegetative community. The drainage channel seed mixture as shown on Table 33a. Proposed Seed Mixture for Drainage Channels, consists primarily of long-stemmed grasses selected for their ability to effectively slow the velocity of storm runoff flows and provide erosion protection to the channel bottom and sideslopes. This mixture also provides rapid vegetative establishment to further minimize the potential for significant erosion. Originally proposed for use in the permanent Magpie Creek Diversion channel, the drainage channel seed mixture is applicable to other drainage channels that, by demonstration, require a vegetative lining to limit flow velocities to below erosive limits. . The cover crop seed as shown on Table 33, Proposed Permanent and Cover Crop Seed Mixtures and Seeding Rates, consists of oats. The specific variety of 2.05.3-20 Revised 5/28/02 Minor Revision No. 45
