prior to mining and are the species utilized locally for intensively <br />managed pastureland. If all native species were established on this <br />site, there would be a significant reduction in the productivity and <br />utility of the pastureland. Thereby, reducing the potential for <br />meeting the postmine land use of pastureland. A seeding rate of 13 <br />pounds, bulk seed per acre is proposed for areas to be revegetated as <br />pastureland. The pastureland seed mixture contains one shrub <br />indigenous to the permit and surrounding area. This woody plant <br />species, big sagebrush, will be seeded at a rate of one pound per acre <br />using the two phase seeding technique described under Planting and <br />Seeding Methods. <br />Inclusion of endemic and exotic species is designed to provide a <br />balanced level of nutrition, prolong the grazing season, create an <br />effective ground cover, enhance forage ; : roduction, and to furnish food <br />and cover for a variety of animal species. The pastureland species to <br />be used by CYCC are those recommended )y Tucker and Herrey (1957) and <br />Steward (1973). The introduced species are documented in these <br />reports as being of superior utility fo forage production. <br />Research documenting the superiority of the introduced species <br />proposed for inclusion in the pastureland and cropland mixtures under <br />conditions similar to those existing on the proposed permit area, are <br />summarized as follows: <br />McGinnies, working on rangeland two miles south of Hayden, Colorado, <br />reported that 15 species were planted in a test plot in 1945 and <br />evaluated until 1958. The most outstanding species on this plot was <br />pubescent wheatgrass followed by intermediate wheatgrass. These <br />species produced the greatest amount of soil protection and forage. <br />Desert wheatgrass was the next best species. Beardless wheatgrass was <br />inferior in inital establishment but appeared to be improving. <br />Species performing fair to poor included green needlegrass, big <br />2.05 -40 <br />
