Site description The proposed Maug Islands IBA is composed of three separate islets that are the remains of a collapsed volcanic cone. They are thickly vegetated mostly with grasses, low scrub, and coconut trees. The proposed IBA is uninhabited and protected by CNMI law as a Wildlife Conservation Area.
Key Biodiversity The entire three-island complex of Maug is proposed as an IBA because of its population of breeding seabirds. The three Maug Islands qualify under the A4i criteria for Brown Noddies and under the A4ii criteria for Red-tailed Tropicbirds. Micronesian Megapodes are common on Maug (Reichel and Glass, 1991). Maug is also home to Micronesian Starlings and Micronesian Honeyeaters. The islands are lushly vegetated (UOG, 1977) and are protected as part of the Northern Islands Conservation Areas (DFW, 2007d).
Non-bird biodiversity: Additional species occurring on the island include Mariana Fruit Bat.
