<br /> <br />tation. Stockpiled topsoil will be replaced, seeded and hole lo- <br />cation marked. <br />Side-hill cuts on roads will be recontoured with the topsoil being <br />replaced and seeded. If road area is strictly temporary, wasted <br />vegetation will be pushed back onto the roadway to discourage sub- <br />sequent use and help reduce erosion. Permanent trails will be <br />water-barred. <br />The following seed mixture will be broadcast at a density of 14 lbs/ <br />acre in early spring or late fall: <br />Four Wing Saltbush 2 1bs/acre <br />Western Wheatgrass 6 lbs/acre <br />Indian Ricegrass 4 lbs/acre <br />Russian Y7ildrye 2 lbs/acre <br />Upon completion, all holes will be filled with tailings to within <br />10 feet of the surface. An expanding plug will then be placed in the <br />hole and filled with cement to within 3 feet of the surface. <br />7. THREATENED AND ENDANGERED SPECIES <br />According to the Bureau of Land Management, there are no threatened <br />or endangered wildlife species within the proposed exploration area.z <br />The peregrine falcon, bald eagle, black-footed ferret and greater <br />sandhill crane are threatened or endangered species that may occur <br />in the exploration area. The habitat is suitable for the peregrine <br />falcon, although none have been sighted. The bald eagle is likely <br />to occur in the area, but their preferred habitat is along the ripa- <br />rian zone of the Colorado River. None have been sighted. Black- <br />footed ferrets are unlikely to occur, since there are no prairie <br />dogs or large populations of ground squirrels to provide a suitable <br />ZU.S. Department of the Interior, Bureau of Land Management, West <br />Central Colorado Coal Environmental Statement, Vo1.3, Map 7a, Wild- <br />life ranges in the Es area: wild horse, bighorn sheep and endangered <br />species: and Map 9, Wildlife ranges in the Es area: raptors. <br />
