community within the shrub stands along the Tie - Across Haul Road corridor would diversify habitat <br />while increasing grazing potential. <br />In the meadow vegetation type, four grasses contributed relative cover greater than three percent in <br />baseline studies. No forbs contributed relative cover values of three percent or more, and shrubs were <br />not a notable component of the type. A minimum of four grasses each will contribute relative cover <br />values of three percent or greater in the reclaimed plant communities. In addition, one forb will be <br />established. Each species will not exceed 75 percent relative cover. Species diversity will not be <br />evaluated on acres returned to cropland for obvious reasons. <br />Woody Plant Density <br />Woody plants and tree species are economically, biologically, and esthetically important to all <br />aspects of post mine land use. SCC has undertaken or cooperated in comprehensive applied <br />research to determine best management practices for establishing woody plants on reclaimed <br />land in Northwestern Colorado. The results indicate that woody plants can be established with <br />varying success. SCC has gleaned from these studies, and actual field experience, that the best <br />possible approach is to: <br />1.) Fence new woody species plots with 8 ft. high elk proof fence; <br />2.) Drill seed or broadcast seed woody species, depending on seed size; <br />3.) Plant seed and seedlings from local genotypes; <br />4.) Transplant local genotype plants; <br />5.) Maximize direct hauled topsoil; <br />6.) Apply vegetation blocking fabric; and, most importantly, for the long -term, <br />7.) Leave large blocks of undisturbed, native vegetation to act as a native seed source, a <br />native source of vegetative propagation, and successful establishment of native woody <br />plants. <br />In regard to point 7) above, SCC permitted for disturbance 1482 acres within the boundaries of <br />the II -W Mine. Of these 1482 acres, SCC actually disturbed only 1286 acres. The undisturbed <br />196 acres, approximately 15 %, are left as islands of mature habitat and seed sources for the <br />eventual successional rejuvenation of the mined land. The islands and border areas of <br />undisturbed plant communities maintained through avoidance mitigation consist of 93 acres of <br />aspen; 63.5 acres of mountain shrub; 26 acres of sagebrush and 6 acres of mesic drainage type. <br />These undisturbed islands and border areas are part of the avoidance mitigation planned for the <br />woody stems in the mined land.
