Cheyenne Bottoms and Quivira National Wildlife Refuge are wetlands of international importance, providing critical habitat for waterfowl, shorebirds, and threatened and endangered species, including whooping cranes, peregrine falcons, least terns, and piping plovers. Cheyenne Bottoms represents nearly 28,000 acres of freshwater wetlands, with ownership divided between The Nature Conservancy (~8,400 acres), Kansas Department of Wildlife and Parks, and private landowners. Quivira National Wildlife Refuge is a federally owned and operated refuge totaling 22,135 acres. Quivira is dotted with rare inland salt marshes that host a diversity of species paralleled only by some coastal marsh and large river habitats. Both wetland complexes are found within the Great Bend Sand Prairie (GBSP) landscap
