Concentrated shrub seeding will be the preferred method of shrub establishment based on existing <br />monitoring results. Some species, however, will be introduced as tubelings, i.e. gambel oak, aspen, <br />and mountain mahogany that do not respond well from direct seeding. Within the original II-W permit <br />area, shrub seeded areas will be approximately one to three acres in size and will primarily be scattered <br />in the two areas illustrated on Exhibit 22-1 (in addition to the specified seedling planting areasl~ <br />Within the II-W South Mining Area, upland shrub establishment areas are designated on Exhibit 22-1 A, <br />as either "Upland Planting Area 1", "Upland Planting Area 2°, or "Seedmix No. 6", with planting list <br />and establishment method based on post-mine site characteristics and desired community. The <br />treatment for Upland Planting Area 1 is combined planting with Planting List 1 and seeding with <br />Seedmix 6, the treatment for Upland Planting Area 2 is combined planting with Planting List 2 and <br />seeding with Seedmix 6, while areas designated as Seedmix 6, are seeding only. The species to be <br />used in seeding or planting these areas are listed on Table 22-6, Seed Mix No. 6- Concentrated Shrub <br />Seeding Areas and Table 22-7, Shrub and Tree Planting Lists. All species are native to the site. Upland <br />Planting Area 3 (Aspen Planting Areas) will also be seeded with Seedmix No. 6. <br />Seed Mix 6 will be broadcast on a roughened seedbed prepared by disking. If the soils are not <br />excessively rocky, the site may be harrowed to aid in lightly covering the seed. If harrowing is not <br />possible, seeding of these sites should be delayed as late in the season as practical. This will allow the <br />anticipated snow cover and freezelihaw process to aid in covering the broadcast seed in areas that <br />cannot be harrowed. Drill seeding will be considered as an optional seeding method when applying this <br />mix. The shrub seeding areas will not be seeded with the permanent seed mix, while disking will <br />suppress the volunteer species present on the replaced topsoil. Reducing herbaceous competition in <br />these areas will enhance the potential for shrub establishment and survival. <br />The small relative size and scattering of the sites will reduce erosion potential in these areas of low <br />herbaceous cover.
