the reference area for species composition and will establish a species diversity standard in <br />consultation with DMG.

However, as of the Spring of 1997, the revegetation <br />success was unacceptable. A meeting was held with DMG and BLM personnel and a plan to reseed <br />the refuse area was developed. <br />Soil Preparation: The RP-1 area was disked or plowed within the first two weeks of May, 1997 to a <br />depth of 8-12 inches. Enough passes were made with the implement to insure burial of the majority of <br />the existing seed bank to at least 4 to 6 inches. The area was disked again in the fall (September) to <br />bury any seed that might have emerged, and prepared for seeding. <br />Herbicide: The interim use of Herbicide (Round-up) as additional treatment was not planned, but <br />would have been an option for areas where disking to the proper depth might not be possible. <br />Seeding: Seeding was done with three (3) separate seed mixes and consisted of three (3) separate <br />application techniques. (See Table V-13 for the seed mix.) In Table V-13, Seed Mix "G" is the basic <br />grass mix and was drill seeded through the standard box of the seed drill to a depth of 1/2 inch. Seed <br />Mix "T" consists of "trashy seeds" and was drill seeded through a drill box equipped with picker wheels <br />for trashy seed. The seeding depth for this mix was 1l2 inch. Seed Mix "B" includes mainly small <br />seeded species and was broadcast seeded. This was accomplished by hydro-seeding, hand <br />broadcasting, or by use of other mechanized broadcasters and was done after drill seeding had been <br />completed. <br />Mulch: Straw mulch was applied to seeded areas following seed application at the rate of 1.0 ton per <br />acre. Straw mulch was crimped with a flat blade disk crimper 1l2" - 2" deep on 8 to 12" centers. <br />Additional Measures: There are a number of rock piles located on top of the reclaimed area. Seed <br />drilling was excluded around these piles for an area of approximately 50-75 feet (irregular) each, with <br />only the broadcastseed mix being applied. This was to enhance the establishmentof less competitive <br />species of (orbs and shrubs. <br />The application rate on the seed mix table for "galleta" assumed that the entire florets would be <br />seeded; the rate was reduced to 0.5 Ibs/acre if this was not the case. <br />ExhibitE-Reclamation Plan Rio Blanco Special Use Permit#81.1 September2000 <br />V-29 <br />
