Site description The proposed Tinian Island IBA encompasses the majority of the island, excluding a small settlement in the southern part of the island and including a large military leasehold area in the north.

Protection status There are no formal protective mechanisms, although the military must ensure the integrity of the National Historical Site and natural features of the area. There are some local, small conservation areas on Tinian, such as the Airport Mitigation Site, a small conservation area in the southwest corner of the island established for Tinian Monarchs, and a small mitigation area in the central part of the island (A. Marshall, pers. comm.).
