Heterogeneity created through patchy disturbance is an important component of grassland conservation, but little research has focused on patch burn-grazing in grassland of the eastern United States. To test the viability of patch burn-grazing in a Tall Fescue-invaded old-field grassland on the Cumberland Plateau, we conducted a prescribed patch burn, stocked cattle, and measured vegetation structure and plant functional group composition. We found that patch burn-grazing creates spatial heterogeneity (patch contrast) for grass height, litter cover, bare ground, and canopy cover of native and exotic grasses. These results suggest that patch burn-grazing is a viable tool for heterogeneity-based grassland management in the region.
