Camp Lake National Wildlife Refuge is a 585-acre refuge in North Dakota where conservation is carried out through an easement arrangement rather than public ownership. The land remains entirely in private hands, while landowners and the U.S. government work together to protect its natural resources. Administered by the U.S. Fish and Wildlife Service from offices at Audubon National Wildlife Refuge, it is significant for demonstrating a cooperative approach to wildlife protection that preserves private ownership while supporting conservation.
