in the shallow areas around the lakes, and the above additional shrubs in the revised seed mix, no <br />other shrub/tree recommendation is proposed by RPM. United should further research the file <br />for the Virginia Acres site to verify if the commitment for additional trees and shrubs were <br />incorporated into the permit. (Willow establishment may help control establishment of <br />tamarisk.) <br />The DOW requested in their wildlife statement United plant tall wheatgrass and yellow <br />sweetclover at rates of 14.5 and 1.0 PLS -lbs/ac respectively. <br />SPECIES (DOW <br />recommendation) Precip. Range Soil Type <br />Tall Wheatgrass 12-14 Any type, saline-sodic <br />Yellow Sweetclover 12-20 Any type <br />Total <br />Bold print indicates undesirable characteristic of the species for site reclamation. <br />3.2 Virginia Acres Pit Revised Seed Mix and Justification: <br />Please see Section 1.2 above. <br />4.0 Recommended Soil Amendments and Site Manipulation: <br />4.1 Site Manipulation: <br />The standard or typical process is to disk and harrow the disturbed site after topsoil replacement, <br />creating a firm seed bed. The next step is to drill seed into the site. However, broadcast seeding <br />into a rough surface may improve seed establishment. Many species used in mine site <br />reclamation are small. If drill seeding depth is not accurately controlled, the seed could be <br />planted to deep, resulting in partial or total seeding failure. Broadcast seeding into a very rough <br />surface scatters the seed in a random pattern into nooks and crannies of broken and loose soil. <br />"Because the seed is deposited on the soil surface and not placed in the soil, some sort of <br />device is usually dragged over the site after seeding to knock some of the seed into cracks <br />and crevices in the soil. This may be followed by rollers or cultipackers to press the seed <br />into the soil for good soil-seed contact. This technique provides variable-depth seeding <br />so necessary with multiple seeded sites and is the preferred seeding method for small- <br />seeded species." (Page 122, Practical Handbook of Disturbed Land Revegetation, F.F. <br />Munshower, 1993) <br />4.2 Recommended Soil Amendments: <br />The soils analyses for two of the sites indicates a deficiency of organic matter, but adequate <br />amounts of nitrogen, phosphorous, and potassium are available.
