Created in 1995, Hackberry Flat Wildlife Management Area, located near Frederick in southwestern Oklahoma, offers 7,120-acres of wildlife recreational opportunities. The Oklahoma Department of Wildlife Conservation, along with many conservation-minded partners, restored this legendary wetland, creating a vast mosaic of wetland habitats for prairie waterfowl, shorebirds and other wetland-dependent birds. Upland areas of native sunflowers and cultivated fields interspersed with mesquite have become one of the state’s premier dove-hunting destinations. Open for scheduled events, the modern William H. "Bill" Crawford Hackberry Flat Center offers interpretive guidance for wildlife enthusiasts, students and educators.
With the completion of the William H. "Bill" Crawford Hackberry Flat Center, this wetland area now offers wetland classroom experiences for school children, meeting facility for workshops, programs and presentations and a place to offer skill development workshops such as waterfowl identification, bird identification and hunter education classes.
