The Guam National Wildlife Refuge protects Ritidian Point and unused military land in the United States territory of Guam. The focus of much of the efforts involves the suppression of invasive exotics to protect endemic species. The reserve consists of eight mostly non-contiguous units.
Ritidian Point Unit
Ritidian Point is at the far northern point of Guam and is the only unit open to the public. The Navy used the area as a high-security communications station throughout the Cold War and donated the 1,203 acres (4.868 km2) of land to the Fish and Wildlife Service in 1993. Guam's Delegate to Congress at that time, Robert A. Underwood, objected to the transfer as a violation of indigenous Chamorro land rights for not returning the property to the pre-military owners. Sailors from the USS Frank Cable continued the Navy connection by volunteering and creating a nature path for visitors.
Ritidian Point contains the archaeological site of a pre-Magellan Chamorro village, a former barrier reef that is now a 500-foot limestone cliff and beaches where threatened green sea turtles nest. This area is the only designated critical habitat in Guam because it is home to some of the last confirmed populations of the Mariana fruit bat, Micronesian Kingfisher, Mariana Common Moorhen and Mariana Crow. The accidental introduction of the brown tree snake is considered the primary cause for the decline of native Guam bird species and the Reserve uses specially trained dogs to hunt them.
Military overlay units
There are seven additional mostly non-contiguous units, one on Andersen Air Force Base and six on various Navy properties. In total, the military owns 95% of the Refuge, 22,456 acres (90.876 km2), and does not allow tourism. The areas are considered an overlay because military needs take precedence but the Fish and Wildlife Service has consulting rights. The areas may face additional stress because of the movement of troops from Okinawa.
These units are largely forested and the main preservation initiative involves the Serianthes nelsonii tree. The critically endangered plant is endemic to the southern Marianas Islands and only one mature tree is known in Guam. Efforts to plant new seedlings have been coordinated through the University of Guam.
