      What We Do

      The National Wildlife Refuge System is a series of lands and waters owned and managed by the U.S. Fish and Wildlife Service. Wildlife conservation is at the heart of the refuge system. It drives everything we do from the purpose a refuge is established, to the recreational activities offered there, to the resource management tools we use. Selecting the right tools helps us ensure the survival of local plants and animals and helps fulfill the purpose of the refuge.
