Description - Guam NWR consists of eight administrative units, five of which are noncontiguous, under two different legal authorities. The overlay refuge contains 22,456 acres in seven Dept. of Defense units on active military bases where the USFWS has consulting rights and management obligations, and a distinct 772-acre fee title area wholly owned and managed by the Service at Ritidian Point.
- The Ritidian Point unit offers 401 acres of adjacent coral reef and deep water marine habitats backed by 321 acres of high limestone cliffs and native limestone forests and a 50 acre beach park.
The overlay refuge hosts the last remaining colonies on Guam of the endangered island swiftlet, Marianas fruit bat, and Marianas crow. Wetland sites on overlay refuge provide habitat for the endangered Mariana common moorhen. The refuge at Ritidian Point was one of the last areas on Guam to lose the native forest birds to the brown tree snake and has retained nesting green sea turtles and foraging fruit bats. A 50-acre beach park is accessible by car, and 1.5 miles of adjacent beach is open only to foot traffic. The development of an education and public use program at Ritidian Point has aided greatly in developing a base of public support.
Recreation - Recreational opportunities at Guam National Wildlife Refuge include environmental education, fishing,
wildlife observation and photography. The Ritidian Unit of the refuge is open from 8:30 a.m. to 4:00 p.m. daily except federal holidays. No pets allowed.
Climate - The year-round temperature averages 27°C (80°F) and the ocean temperature a pleasant 27.2°C (81°F) May to November is the rainy season, and you can expect wet, hot, and humid days. Temperatures cool down from November through April, the dry season, and tropical trade winds are common.
The Ritidian unit is located along the northernmost point of Guam.
