Alteration of Bison and Black-Tailed Prairie Dog Grazing Interaction by Prescribed Burning

Abstract
Bison (Bison bison) use of a black-tailed prairie dog (Cynomys ludovicianus) colony was compared before and after a prescribed burn on adjacent, uncolonized grassland at Wind Cave National Park (WCNP), South Dakota, 1979-80. On a daily basis cow-calf herds increased their use of the burned grassland 12 .times. and decreased their use of the colony by 30-63% following the burn. Prescribed burns could be effective in mitigating bison impacts on colonies.
