Hunting is one of the many tools used to manage Custer State Park's wildlife. Hunting helps reduce the size of populations, preventing overcrowding with the park. Controlling animal numbers ensures an adequate supply of food for all species and prevents habitat degradation and loss as well as competition between species. Most hunting seasons typically occur from mid-September through early January. Turkey hunting takes place in the spring from mid-April through mid-May each year. The fees collected from hunting licenses generate revenue which help fund wildlife management programs. Species managed through hunting with the park include bison, elk, deer, pronghorn, mount lion, and turkey. With the exception of buffalo, all seasons are resident only.
