• and wildlife, good forage production potential, compatibility with naturally regenerating native species <br />present in replaced topsoil, and the ability to be self-sustaining or compliment successional processes in the <br />reclaimed plant communities. Attainment of these goals, in tum, fadlitates achievement of the postmining <br />land uses. <br />To finalize the plant materials lists, dominant or commonly occurring species identified in the regional <br />vegetation baseline studies were evaluated for inclusion in the seed mixes or planbng lists. The list of these <br />species was further refined to include the more desirable (i.e., no noxious or strong increaser spedes) or <br />high utility spades. <br />Realistic and consistent market availability was an additional selection crRerion considered for all potential <br />spades and varieties. Included spades which were not present in vegetation baseline studies were added <br />to aid in achievement of the revegetation goals specified eadier. Finally, analysis of revegetation monitoring <br />data collected at the Seneca II Mine since 1985 and review of pertinent revegetation literature was <br />performed. The resulting information provided insights into seeded species performance, seeding rates, <br />stand composition, planting rates, antidpated survival percentages, and the degree to which natural <br />regeneration compliments the seed mixes. <br />• Seed Mix No. 1 (Table 13-1) has been designed for all reclaimetl upland sites and ephemeral drainages on <br />the mine area. The 24 species contained in the mix are adapted to a broad range of site conditions as <br />noted following the mix. Site differences related to aspect, topography, moisture conditions, and topsoiling <br />will compliment Seed Mix No. 1, allowing for variation in established species composition from site to site <br />and increasing opportunities for diverse cemmunfties and habitat. Natural regeneration, variable in <br />composition and degree, will also contribute to diverse reclaimed communities. Shrub planting areas, <br />described in following sections, are included to further enhance the diversity of the redaimetl upland areas <br />and ephemeral drainages. <br />Seed Mix No. 2 (Table 13.2) will be used in areas that are likely to have wet or potentially wet site conditions. <br />Additional sites where this mix may be used include areas around permanent ponds. The species listed in <br />the mix provide the basis for redevelopment of mesic site drier phase or riparian communities. Native <br />species, which are not available as seed or seedlings, will reestablish in reasonable time frames because of <br />the availability of native plant propogules in the proximity of the reclaimed areas. Observations of previously <br />disturbed similar areas at the Seneca II Mine indicate Tvoha, Carex, and Juncus species have reestablished <br />naturally. Selected shrub or tree plantings, as discussed later, will complete reclamation of these sites. <br />u <br />TR-37 13-11 Revised 04/05 <br />
