Map by USFWS/ Rod Low and Susan Machida   Guam National Wildlife Refuge (NWR) was established with the Ritidian Unit, which was excessed by the U.S. Navy. Most of the refuge, about 22,500 acres, is an "overlay refuge" on lands administered by the U.S. Air Force and U.S. Navy. Although the military mission comes first on these lands, the U.S. Fish and Wildlife Service assists in protecting native species and habitats. Guam NWR provides habitat for the last remaining populations of the endangered Mariana fruit bat, Mariana crow, and the Serianthes nelsonii tree. The brown tree snake is considered the primary cause for the decline of native Guam bird species. The Refuge also protects significant cultural resources of the Chamorro people.     For more information: Refuge Manager Guam National Wildlife Refuge P.O.
