Sites where roughening by the above-mentioned methods is not practical (e.g., steep slopes, rocky areas, etc.) will be dozer-tracked perpendicular to the slope or otherwise left with adequate roughness following topsoil placement to provide microsites for seed germination and to reduce soil movement. 2.4 Fertilization It will not be necessary to apply fertilizers or lime to reclaimed sites because the majority of the topsoil will have been stockpiled for only a short time. Furthermore, fertilization may enhance weed growth. Fertilizer will only be used if recommended by the BLM or other landowner. 2.5 Revegetation The following seed mixtures, seeding rates, and seeding methods have been developed in consultation with the White River Resource Area BLM. 2.5.1 Species Selection Selection of plant species for revegetation is primarily based on native plant community composition and existing soil types. Individual species' establishment potential, growth characteristics, soil stabilizing qualities, palatability to wildlife and livestock, and commercial availability are also considered, as well as post-construction land use objectives and agency recommendations. Certified, weed-free seed will be used whenever possible, and, in all cases, seed will be free of primary noxious weeds. Seed labels from each bag will be available for inspection while seeding is in progress. 2.5.2 Revegetation Mixtures and Rates The basic seed mixture and seeding rate presented in Table 1 are based on recent BLM recommendations and similar projects on parallel pipeline corridors. Seeding rates are presented in pounds of pure live seed (PLS) per acre based on application rates for drill seeding. Broadcast or hydroseeding rates (if used) will be roughly twice the drilling rates. The seed mixture and seeding rate presented in Table 2 apply to private land in the Parachute Creek valley owned by Unocal (Bio-Resources 1995). These seeding specifications are assumed to be appropriate for the Yankee Gulch Project pipeline but could be adjusted based on future negotiations with Unocal. In accordance with the Colorado Division of Wildlife's request, forb species known to be beneficial to sage grouse will be included in the revegetation seed mixture to enhance sage grouse habitat. This will apply to appropriate sage grouse habitats along Barnes Ridge. Forb species to be added will include dryland alfalfa (Medicago sativa), small burnet (Sanguisorba minor), and sainfoin (Onobrychis viciaefolia).
