• Table 26, Ground Cover Mixes, represents WFC's revised mix for the <br />New Elk Mine. WFC's proposed postmining land use for the New Elk are <br />rangeland and wildlife habitat. Wildlife habitat is divided into two <br />habitat types, riparian and upland. The basic rangeland mix will be used <br />in all seedings. As shown in Table 26, additional species are added to the <br />rangeland mix for each of the habitat types. WFC is proposing the revised <br />rangeland mix because it has been successful on revegetation of the side <br />slopes of the Purgatoire River diversion. To supplement the rangeland seed <br />mix for upland wildlife habitats, WFC will transplant relatively equal <br />amounts of trees/shrubs indicated in Table 26, representing approximately <br />1,500 trees/shrubs/acre. This planting density will apply for the refuse <br />disposal area, water tank benches and access roads. To supplement the <br />rangeland seed mix for riparian wildlife habitats, WFC will transplant <br />willows and cottonwoods on 5 foot centers. This standard will apply for <br />the prep plant and ponds 004, 006 and 007 areas. <br />Seeding methods will include drilling, broadcasting and <br />• transplants. Drilling will be acoortq~lished on slopes less than 3H:1V. <br />Broadcasting will be accomplished on steeper slopes with mechanical <br />broadcasters, hand broadcasters or by hydroseeding. idiere the broadcast <br />seeding method is utilized, seeding rates will be doubled. WFC was very <br />pleased with the hydroseeding efforts on the Middle Fork diversion and <br />refuse area dam and slopes. In addition, we observed significantly mere <br />germination and less erosion in areas where slopes were left in a roughened <br />condition. <br />Mulching will include either application of straw or hay mulch at <br />a rate of 2 tons/acre. Straw or hay will be crimped after application. <br />WFC will also utilize hydrocmrlching at an equivalent rate of straw or hay <br />mulch. <br />No irrigation is planned for the land uses proposed during the <br />permit term. However, it is conceivable after closing the New Elk <br />facilities, flood irrigation may occur on the rangeland adjacent to the ~~~ <br />.
