The proposed Guguan Island IBA is uninhabited and protected by CNMI law as a Wildlife Conservation Area. The volcanic island is free of large introduced mammals. The coast is bordered by steep basaltic rock with gables of high ridges which contain deep, rain-eroded gorges.
The entire island of Guguan is proposed as an IBA under A4i and A4iii criteria. The island qualifies as an IBA under A4i criteria for Grey-backed Terns and Sooty Terns. The island qualifies under A4iii criteria for its total seabird population. Guguan is also home to Micronesian Megapodes, White-throated Ground-Doves, Micronesian Starlings, Collared Kingfishers, and Micronesian Honeyeaters (DFW, 2007b).
Non-bird biodiversity: Additional rare and endangered species on the island include Mariana Fruit Bat.
