Abstract: Since 1996, Tennessee Valley Authority (TVA) natural resource managers have established native warm-season grasses, forbs, and legumes on numerous parcels of TVA managed lands ranging from upper east Tennessee through northern Alabama to western Kentucky. Principal objectives driving these efforts included: eradication of non-native invasive plant species and enhancement of grassland/early successional wildlife habitat (650 acres); development of native grass forage crop demonstrations (50 acres); timber salvage site restoration (75 acres); and visual/aesthetics improvements associated with high dispersed recreation public use areas and residential shoreline demonstration projects (30 acres). A variety of partners and stakeholders assisted in these efforts, including state wildlife agencies, non-government organizations, native plant nurseries/seed producers, local agricultural licensees, and universities. Several native species mixtures have been used, depending on local site conditions and specific project objectives. Typical grassland wildlife habitat enhancement projects used a mixture of three or four native grass species with one or more native legumes. On projects where visual/aesthetics/observable wildlife was the driver, more native wildflowers were added to mixtures. On agricultural forage crop demonstrations, single native grass species, such as big bluestem or switchgrass, were used with mixed species field buffers. These native plant stands have been managed with periodic prescribed fire, mowing for hay crops, disking, and applications of selective herbicides.
