The wetland management district wetland management district
A wetland management district is a U.S. Fish and Wildlife Service office that manages waterfowl production areas in one or more counties. Waterfowl production areas are small natural wetlands and grasslands that provide breeding, resting and nesting habitat for waterfowl, shorebirds, grassland birds and other wildlife. The Fish and Wildlife Service acquires waterfowl production areas under the authority of the Migratory Bird Hunting and Conservation Stamp Act, primarily using funds from the sale of Federal Duck Stamps. The Refuge System’s 38 wetland management districts comprise thousands of waterfowl production areas – almost all in the Prairie Pothole Region of the Northern Great Plains.
