Species considered failures were tall wheatgrass, stiffleaf wheatgrass, <br />• blue wildrye, and short-awned barley. <br />Working on disturbed soils at Axial basin, Draves and Berg (1978) <br />reported the results of 24 grass and 16 forb species. Of the 24 species <br />planted, second highest plant cover was produced by intermediate <br />wheatgrass, pubescent wheatgrass ranked fourth, smooth brome ranked fifth, <br />and desert wheatgrass ranked fourteenth. Of the forbs, alfalfa produced <br />the highest plant cover. Cicer milkvetch also produced an abundance of <br />cover. These two forbs are included in the proposed seed mixture because <br />native,~legumes cannot be expected to provide adequate erosion control and <br />forage production. <br />After four growing seasons, Sims (1977) reported the results of 25 <br />grass and 19 forbs species seeded on test plots in the Piceance Basin. The <br />best producing grass was pubescent wheatgrass, the third best was meadow <br />brome, fourth best intermediate wheatgrass, seventh best desert wheatgrass, <br />ninth best was smooth brome. Timothy ranked 21st. Among the legumes, <br />alfalfa ranked second, while titer milkvetch ranked fifth. <br />Merkel, et. al. (1974) reported that of ten species planted at Meeker, <br />• the best performing species were intermediate and pubescent wheatgrasses. <br />Only western wheatgrass of the native species planted could be considered <br />successful. <br />Upon evaluating the establishment of various plants seeded on <br />unleveled spoils at the Seneca Mine, Berg (1975) found that of the species <br />planted, orchardyrass produced the highest frequency based upon the amount <br />of seed planted. Following orchardgrass, in descending order, were desert <br />wheatgrass, smooth brome, and alfalfa. <br />Species Diversity Success Standard <br />CWI proposes to adopt a species diversity success criteria which also <br />compliments the proposed rangeland/wildlife land use goals. CW1 will <br />consider its final reclaaation a success regarding species diversity if the <br />vegetation reflects the following criteria: <br /> a) There are at least 5 native perennial herbaceous species (4 native <br /> -4- <br />
