Kulm Wetland Management District (WMD) in south-central North Dakota was established in 1971. Located in the heart of the Prairie Pothole Region, the District provides secure breeding, nesting, and brood rearing areas for many species of waterfowl and other migratory birds. The District currently manages 201 Waterfowl Production Areas (WPAs) (45,683 acres), three easement and small fee National Wildlife Refuges, and 120,000 acres of wetland and grassland easements. Glacial action created a wealth of wetlands, which attract waterfowl breeding pair densities exceeding 100 pairs per square mile in some parts of the District. Native prairie is still well represented in the area and supports many species of upland nesting birds. The James River meanders through the eastern portion of the District. As it leads south to the Missouri River, it forms a major migration corridor for numerous species of migrating birds.
