Seneca Coal Company Weed Management Plan <br />• <br />Seed Mlix for Permanent Revegetatflon <br />(Continued) <br />• <br />• <br />Species Characteristics and Adaotabilit <br />Xeric Sites: All species <br />Mesic Sites: Agropyron smithii, A. trachycaulum, Bromus, Dactvlis, <br />Elvmus cinereus, Poa amola, Stioa viriduta, Medicago, <br />Aster, Achillea, Lupinus, Prunus, Amelanchier, <br />and Svmohoricaroos <br />Clay to Sandy Textured Soils: All species <br />Soils Coarser Than Sandy Soils: Agropvron dasvstachvum, A. soicatum, 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 dasvstachvum, A. smithii, Poa compressa, Achillea, <br />Aster, Prunus, Amelanchier, and Svmohoricarpos <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 far <br />substitutions. When cultivars are unavailable, regional native sources will be used. Complete lack <br />of availability will normally be limited to the native Torbs and shrubs listed. Substitutions in this case <br />will be determined by reviewing the native species list and selecting atlapted antl desirable native <br />species replacements offered by seed dealers. Any substitutions will be noted in the Annual <br />Reclamation Report. <br />9 <br />January 2005 <br />
