Abstract: Since the mid 1970s, a long-term project has investigated and demonstrated effect plant cover for highly disturbed surface mine lands in the Northeast. From initial plot trials, the work has progressed through large-scale plantings and evaluation of planting technique and planting date, to application. Testing has included grass-forb mixtures and grass-introduced legume mixtures. Native warm season grasses have become the preferred cover type, with an evolution of the recommended six mix over time. Plantings on mined sites with percent fines below 15 have only been successful with native grass. No topsoil replacement has been required. Native warm season grasses appear to stabilize and moderate site conditions to the point that volunteer species are able to establish on sites that had previously remained bare for several decades. Effective planting technique involves the use of bulldozers to track the broadcast seed into the surface. Germination reliably occurs in the cleat marks providing a good spatial distribution of plants. Success with native grasses has been demonstrated in locations with frost-free seasons as short as 100 days, however aspect does make a large visual difference in plat biomass production on those areas.
