Abstract: The restoration of mined land begins by recognizing plant species that can respond to management under poor soil conditions. The objective of this study was to assess potential use of plant species for partially reclaimed mined land. The study was located at the Powell River Project Education Center in southwest Virginia. Sixteen treatments were established in the summer of 1990 using 12 plant species in pure stands and mixtures in a split plot arrangement with 4 replications. Prior to establishment, a 2:1 mixture of composted wood chips and dry sewage sludge (112 Mg ha-1) was applied to provide nitrogen, phosphorus and organic matter. Biomass samples were collected from 1996-2001 to determine botanical composition and biomass production. Samples were separated by target species (the species originally planted), and non-target grasses, forbs, and legumes. Switchgrass produced the most biomass (8.9 Mg ha-1) across years compared to other grasses. Grasses showed a higher target biomass in 1996 compared to 1997 and 1998. Significant differences were observed in bioeffeciency with switchgrass, tall fescue, and reed canarygrass having the highest value. Data showed that species chosen for revegetation of those oils could provide opportunities for changing land use but it will depend o the intended post-mine use of these soils and the plant species being utilized.
