noted following the mix. Site differences related to aspect, topography, moisture •~ <br />conditions, and topsoiling will compliment Seed Mix No, 1, vary the species composition <br />from site to site, and provide opportunities for diverse communities and habitat. Natural <br />regeneration, variable in composition and degree, will also contribute to diverse <br />reclaimed communities. Shrub pt anting areas, described in following sections, are <br />included to further enhance the diversity of the reclaimed upland areas and ephemeral <br />drainages, <br />Seed Mix No. Z (Table 22-2) will be used in areas that are likely to have wet or <br />potentially wet site conditions such as the reclaimed haul road areas along the Dry Creek <br />drainage and the far eastern edge of the tie-across haul road. Additional sites where <br />this mix may be used are the vicinity of Ponds 005 and 006 and any other permanent ponds. <br />The species listed in the mix provide the basis .for redevelopment of mesic site or <br />riparian communities. Native species, which are not available as seed or seedlings, will <br />reestablish in reasonable time frames because of the availability of native plant <br />propogules in the proximity of the reclaimed areas. .Observations of similar areas at the <br />Seneca II Mine indicate Ty ha, Ca rex, and Junc us species have reestablished naturally. <br />Selected shrub or tree plantings, as discussed later, will complete reclamation of these <br />sites. <br />Seed Mix No. 3 (Table 22-3) is designated for reclaimed areas within the tie-across haul <br />road corridor. The miz has been designed for the wet saline or alkaline conditions and <br />heavy textured soils which are likely to be present within this area. In particular, the <br />western end of the haul road corridor and many of the drainages were web and <br />saline/alkaline prior to construction of the haul road. Dryland wheat farming using <br />summer fallow techniques to enhance soil moisture levels is a major source of these <br />conditions which will continue following reclamation. Many of the species in the mix will <br />tolerate wet conditions and all are adapted to varying saline/alkaline conditions. Soil <br />textures on reclaimed sites will be clay loam to clay. All species in Seetl Mix No. 3 are <br />able to tolerate these heavier textured soils. <br />Topsoil stockpiles, areas requiring temporary reclamation for approximately one year or <br />longer, and roadside disturbances will be seeded with Seed Mix No. 4 (Table 22 -4). <br />Species selection was based on the need for rapid establishment; longevity; adaptability <br />to a range of soil textures, aspects, and slopes; sod forming ability; presence of species • <br />that have deep root systems or a large and fibrous root mass; and a level of nitrogen <br />16 <br />
