The use of mycorrhizal innoculants in containerized seedlings is a recently developed technology. • These innoculants have been developed from soil resources collected from native areas adjacent to mine sites. It is anticipated that reestablishment of plant- mycorrhizal relationships may aid in more rapid shrub establishment and development Big game depredation continues to be a serious problem in planting areas. Use of repellants such as Deer -Away have been somewhat effective through the first growing season. Measures will continue to be researched to extend the period of effective control. The distribution of planting arrangements in the mine area has been planned to keep travel distances for wildlife between shrub establishment areas and large areas of undisturbed native vegetation at less than 1000 feet. As can be seen on Exhibit 22 -1, Posmilning Vegetation, distances from the proposed shrub establishment areas to the edge of extensive mining disturbance is .400 feet to 900 feet Distances between the proposed planting sites vary from 300 feet to 800 feet Distances for the mesic drainage sites are less. Various factors may affect the final location of a planting or transplant area. These include variation in localized topographic relief due to final grading or the sequencing of operations that may split a • planting area into several years. In the latter case, it may be more beneficial to adjust the planting location to complete the entire planting. The availability of better topographic relief or aspect, and hence better planting site, will take precedent in locating a final planting site. Seed acquired for the various seed mixes will be of the highest quality possible. The addition of large numbers of native species (harvested from native sources) will contribute larger quantities of trash and inert matter. However, all seed mixes are specified on a PIS basis, ensuring the proper amount of viable seed is being applied. Sources for seed will be on a regional basis whenever possible, particularly for the native harvest species. Representative seed tags will be presented in the annual reclamation report. Native species predominate in all mixes, including Seed Mix No. 4 for temporary reclamation. The following species, by seed mix, are introduced. Seed Mix Nos. lA and 1B Orchardgrass Alfalfa Seed Mix No. 2 None Seed Mix No. 3 Alkaligrass • Alfalfa Seed Mix No. 4 Alfalfa PR -02 21 Revised 01/06
