The model developed in this study found that wildlife habitat could be improved by reducing cattle (Bos taurus) grazing intensity from 556 AUMs to 325 AUMs on the study site. Heavy grazing pressure was found to decrease Northern bobwhite (Colinus virginianus) nesting cover, protective cover, and brood habitat. Reducing cattle grazing intensity is needed to sustain these habitat features. As bobwhite and white-tailed deer (Odocoileus virginianus) habitat improves, season-long grazing would replace early-season summer grazing. The negative effects of grazing on nesting cover can be reduced as grazing intensity is minimized from April through mid-July. Overall, the model found that adequate herbage can be produced for an economically feasible amount of livestock production and improved bobwhite and deer habitat through the use of herbicides, prescribed burning, prescribed grazing, and small-scale habitat manipulation. The canopy is opened and a greater amount of herbage is produced through the practices of herbicide utilization and prescribed burning.
