REVEGETATION RECOMMENDATIONS Summary: The revegetation recommendations should include methods to save existing topsoil, gro~md preparation, slopes, mulching specifications, seed and method of seeding, fertilization, and maintenance follow up. Topsoil: Although the present topsoil is limited is depth, it vill xork as a medium for plant growth. As explained by Cliff Thorne the topsoil is presently being stockpiled and used as the revegetation process continues. A cover of topsoil /. - 6" in depth with the present material could be used. I would also leave all rocks in the soil on the area to be reseeded. The rocks will act as moisture retainers by shading small areas, and provide areas where the grass seed will be protected from adverse conditions. The rocks will also blend in with the present landscape. Slopes: 4rhere possible, the slopes that are to be revegetated should be kept at a 3:1 or flatter. If this is not possible the soil should be left at an angle close to the natural angle of repose for the soil. (1-~ -1 or 2 - 1). Since the area to be revegetated will not cover a large portion of the mine site, the slopes should be left rough enough to prevent water from concentrating and causing gully erosion. 'where xater from an adjoining slope rill cross the slope to be revegetated, a small berm on grade should be constructed to exit the water to an area which is vegetated and the possibility of erosion is lessened. Gronad Preparation: Areas to be reseeded should have 4 - 6" of topsoil (use soil on site) applied. The top- soil should be applied to a roughened surface to prevent slippage and to form a better bond betxeen the overburben and the soil. MulchiaQ: I strongly recommend a mulch be placed over the area that is seeded. Astray mulch or an application of manure in clod form xill help retain moisture, protect neu seeding, m;*+;~;ze high intensity storm impact end prevent serious vind erosion. If stray mulch is used it is recommended that 70 - 90 lbs. of stray hay/100"sq. ft. be used. After the hay is applied it should be crimped into the soils with a crimper xith strainght discs. Fertilization: Just before the seedbed is to be final graded an application of fertilizer to aid plant establish- ment should be applied. A fertilizer with a high nitrogen high ghosphorus content should be used (30-20-6). The fertilizer should be spread at a rate of 1 lb/1000 sq. ft.
