• Section 4.6 provides details on methods. Such transplants will have the added benefit of using <br />native species and genotypes of plants for revegetation. This will be a valuable source of <br />difficult to obtain native species. <br />Tables 3.6-7, 3.6-8, and 3.6-9 list the preferred species for reestablishing on each range site <br />occurring within the proposed mine permit area. The proposed species mixes favor grasses <br />and (orbs. At a minimum, 14 herbaceous plant species will be seeded and/or transplanted <br />within each range site to be revegetated. The total number of genera and species to be <br />reseeded are based generally on the dominant species determined by the diversity index for <br />each range site (Section 2.3). A comparison of the species mixes in Tables 3.6-7, 3.6-8 and 3.6-9, <br />and the diversity Tables 2.3-15 through 2.3-20 will show that Trapper Mine species mixes are <br />more diverse than what existed prior to mining. Such an approach is necessary since one may <br />not predict precisely how reseeded species on reclaimed mined land will react over time. By <br />March 15 of each year, the Division will be provided with the proposed species list to be <br />seeded that year according to range site or area of use. This is necessary since seed <br />availability on a year -by -year basis varies. <br />Not less than 30 PLS per square foot will be seeded if drilled or 45 PLS per square foot if <br />broadcast seeded. <br />• Range Site B <br />For revegetation purposes, range site B is mountain shrub type below 7200 feet and above 6700 <br />feet in elevation. The species mix for this range site is presented in Table 3.6-7. During the <br />permit period, select species continued in Table 3.6-7 will be seeded and/or transplanted within <br />the described approximate elevation range. Generally, all seeding will be accomplished in the <br />fall of the year. Spring seeding may be used for drainageways, cropland areas and transplants <br />may be planted fall through spring. <br />Introduced species found in the species mix for range site B are fairway crested wheatgrass, <br />Agropyron cristatum; pubescent wheatgrass, A. trichophorum; <br />3-127 <br />
