Things To Do

Wildlife Watching


Guam National Wildlife Refuge was established in 1993, to protect and recover endangered and threatened species, protect habitat, control non-native species with emphasis on the brown tree snake, protect cultural resources, and provide recreational and educational opportunities to the public where possible.

The refuge 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.

The refuge is composed of 1,203 acres (371 acres of coral reefs and 832 acres of terrestrial habitat) owned by the U.S. Fish and Wildlife Service, and 22,456 acres (mostly forest) of refuge overlay owned by the Department of Defense in Air Force and Navy installations. The Ritidian Unit, which is owned by the Fish and Wildlife Service, was created from a small decommissioned, specialized naval installation.

The refuge receives over 90,000 visits a year from island residents and tourists. Current plans are to renovate the facilities to improve research capabilities, improve administrative and maintenance capabilities of the refuge staff, and establish a visitor and interpretive center.
