Location and Contact Information

      About Us

      Guam National Wildlife Refuge is located on the island of Guam, an unincorporated U.S. Territory. Guam is the largest and southernmost island in the Mariana Archipelago, situated in the western Pacific Ocean, approximately 3,800 miles west of Honolulu and 1,500 miles south of Tokyo.

      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.

      Our Species

      The Refuge provides habitat for the last remaining populations of the endangered Mariana fruit bat, Mariana crow, and the Serianthes nelsonii tree. The Ritidian Unit is an active sea turtle nesting area. 

      Get Involved

      The Guam National Wildlife Refuge relies on volunteers to assist in vital conservation and management efforts to preserve national networks of land and water - including both flora and fauna - for the benefit of present and future generations.
