The Lostwood Wetland Management District is located in the U.S. state of North Dakota and extends from the Canada–United States border to the neighboring state of Montana. The district consists almost exclusively of privately owned property, and landowners work cooperatively with the U.S. Fish and Wildlife Service to manage the land to maximize natural and agricultural needs. Hundreds of small bodies of water, wetlands and uplands are set aside to increase bird productivity and provide habitat for native animals and plants. The district comprises various areas spread throughout northwestern North Dakota which include waterfowl production areas, wetland easements, grassland easements, and easement refuges. The properties are located in Mountrail and part of Ward County, North Dakota.
