• Saecies Diversity One year prior to planned reclamation of the alluvial well area, BME will samble <br />the reference area for species composition and will establish a species diversity standard in <br />consultation with DMG. The prescribed seed mix and woody plant stocking rates may change <br />based on this sampling and consultation with DMG to achieve the specific reclamation objectives. <br />V.1.4.i Remedial Treatment of Refuse Area 1 <br />The refuse area 1 (RP-1) was reclaimed in 1990. However, as of the Spring of 1997, the <br />revegetation success was unacceptable. A meeting was held with DMG and BLM personnel anq a <br />plan to reseed the refuse area was developed. <br />Soil Preparation: The RP-1 area was disked or plowed within the first two weeks of May, 1997 tq a <br />depth of 8-12 inches. Enough passes were made with the implement to insure burial of the majority <br />of the existing seed bank to at least 4 to 6 inches. The area was disked again in the fall <br />(September) to 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 tt~e <br />• basic grass mix and was drill seeded through the standard box of the seed drill to a depth of 1/2 <br />inch. Seed Mix'T' consists of "trashy seeds" and was drill seeded through a drill box equipped with <br />picker wheels for trashy seed. The seeding depth for this mix was 1/2 inch. Seed Mix "B" includ@s <br />mainly small seeded species and was broadcast seeded. This was accomplished by hydro_ <br />seeding, hand broadcasting, or by use of other mechanized broadcasters and was done after drill <br />seeding had been completed. <br />Mulch: Straw mulch was applied to seeded areas following seed application at the rate of 1.0 tGn <br />per acre. Straw mulch was crimped with a flat blade disk crimper 1/2" - 2" deep on 8 to 12" center;. <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, <br />with only the broadcast seed mix being applied. This was to enhance the establishment of IeSs <br />competitive species of fortis 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 />During the summer of 1999 several problems were observed with the revegetation of Refuse Area <br />#1. First, Cheatgrass had again become a dominant invader on portions of the site. Second, in <br />areas with substantial perennial vegetation the plant community is composed of an overwhelming <br />• dominance of grasses. The following plan is designed to help address both issues. <br />Mid-Term Review 2002 (8/2002) V-48 <br />
