- The Flint Hills NWR lies in the broad, flat Neosho River Valley. The refuge is named for the gently rolling fossil-studded limestone hills to the west of the refuge.
The refuge is managed primarily to benefit migrating and wintering waterfowl in the central flyway. A variety of management practices are utilized to meet the needs of wildlife.
Along with large numbers of migrating birds the refuge is also a haven for whitetail deer, bobwhite quail, wild turkey, river otter and a diversity of other mammals, neotropical birds, reptiles and insects.
