Lost Lake National Wildlife Refuge is a nine-hundred-sixty-acre protected area in North Dakota managed through an easement arrangement that keeps the land in private ownership. Landowners and the U.S. government work together to conserve its natural resources, while oversight is provided by the U.S. Fish and Wildlife Service from Audubon National Wildlife Refuge. Its importance rests in this cooperative conservation approach, which protects habitat without requiring the land to be transferred from private hands.
