Concentrated shrub seeding will be the preferred method of shrub establishment based on existing <br />monitoring results. Some species, however, will be introduced as mbelings, i.e. gambel oak, aspen, <br />and mountain mahogany that do not respond well from direct seeding. Within the original II-W <br />permit azea, shrub seeded aeeas will be approximately one to three acres in size and will primarily be <br />scattered in the two areas illustrated on Exhibit 22-1 (in addition to the specified seedling planting <br />aeeas). <br />Within the II-W South Mining Area, upland shrub establishment aeeas are designated on Exhibit 22-I, <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 foe 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 aeeas designated as Seedtnix 6, aze seeding only. The species to be used <br />in seeding or planting these aeeas aze listed on Table 22-6, Seed Mix No. 6- Concentrated Shrub <br />Seeding Areas and Table 22-7, Shrub and Txee Planting Lists. All spedes aze native to the site. <br />Upland Planting Area 3 (Aspen Planting Areas) will also be seeded with Seedtzux No. 6. <br />Seed Mix 6 will be broadcast on a roughened seedbed prepared by disking. If the soils aze not <br />excessively rocky, the site may be harrowed [o 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 />antidpated snow cover and freeze/thaw process to aid in covering the broadcast seed in aeeas that <br />cannot 6e harrowed. Drill seeding will be considered as an optional seeding method when applying <br />this mix. The shrub seeding aeeas will not be seeded with the perrttanent 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 aeeas of low <br />herbaceous cover. <br /> <br />• <br />• <br />PR03 <br />22 <br />Revised 4103 <br />
