118 04/2024 <br />REVEGETATION PLAN <br />The approved revegetation plan emphasizes native species planting resulting in a diverse, <br />permanent, effective plant community capable of self-regeneration. <br />Species and Planting Methods <br />Plant species proposed for use in revegetation were selected considering local environmental <br />features of soils, nutritional value, slope, elevation, and precipitation, as well as the vegetational <br />potential of the site. The current seed mix is entirely composed of native species. Warm season <br />graminoid species predominate in the mix, as they do in the native area adjacent to the mine. <br />DRMS, CPW and the NRCS have all agreed that sand sage (Artemisia filifolia) need not be <br />included in the seed mix. The current seed mix is presented below: <br />Common Name Latin Name Character Seed Rate <br />#PLS/acre <br />Sideoats Grama Bouteloua curlipendula native warm season 1.5 <br />Prairie Sandreed (Goshen) Calamovilfa longifolia native warm season 1.5 <br />Sand Bluestem (Garden City) Andropogon hallii native warm season 2.0 <br />Blue Grama (Lovington) Bouleloua gracilis native warm season 0.5 <br />Switchgrass (Pathfinder) Panicum virgatum native warm season 0.5 <br />Indian Ricegrass (Paloma) Oryzopsis hymenoides native cool season 1.0 <br />Yellow Indiangrass (Oto) Sorghastrum nutans native warm season 1.5 <br />Thickspike Wheatgrass (Critana) Agropyron dasystachyum native cool season 0.3 <br />Little Bluestem Schizachyrium scoparium native warm season 0.5 <br />Prairie Coneflower Ratibida sg. native forb 0.3 <br /> Total # PLS/acre 9.6
