Surface mining in the Appalachian region of Kentucky often involves steep slopes and spoil limitations for revegetation not encountered in other reclamation situations. Herbaceous species (mono cultures or mixtures) provide quick cover required in revegetation of mined land for control of erosion as well as promoting soil development, improving wildlife habitat, and livestock production through hay and pasture production as well as a potential use as renewable energy for cofiring with high sulfur coal. However, due to the many challenging chemical and physical characteristics of mine spoil, selection of adaptable herbaceous species should be carefully considered.
