Seneca Coal Company Weed Management Plan <br />t <br />Seed Mix for Permanent Revegetation <br />(Continued) <br />Species Characteristics and Adaptability <br />Xeric Sites: All species <br />Mesic Sites: Agropvron smithii A. trachycaulum Bromus Dactylis <br />Elymus cinereus Poa ampla Stiva viridula Medicago <br />Aster Achillea Lupinus Prunus Amelanchier <br />and Symphoricarpos <br />Clay to Sandy Textured Soils: All species <br />Soils Coarser Than Sandy Soils: Agropvron dasystachyum A. spicatum Festuca Poa, <br />Penstemon Lupinus Prunus Amelanchier and Purshia <br />Cool Season: All species except Medicago Achillea and Aster <br />Warm Season: Medicago Achillea and Aster <br />Rhizomatous Species: Agropvron dasystachyum A. smithii Poa compressa Achillea <br />Aster Prunus Amelanchier and Symphoricarpos <br />Species substitutions will only occur when availability of any of the listed species is a problem. The <br />species listed in Seed Mix No. 1 have been selected for normally consistent availability. However, <br />adverse environmental conditions and excessive market demand may occasionally limit supplies. <br />For species that have several developed cultivars, alternative cultivars will be evaluated for <br />substitutions. When cultivars are unavailable, regional native sources will be used. Complete lack <br />of availability will normally be limited to the native forbs and shrubs listed. Substitutions in this case <br />will be determined by reviewing the native species list and selecting adapted and desirable native <br />species replacements offered by seed dealers. Any substitutions will be noted in the Annual <br />Reclamation Re <br />E <br />January 2005 <br />
