Oahu Offshore Islet Seabird Sanctuaries
The majority of seabird-nesting colonies in the main Hawaiian Islands are located on the offshore islands, islets and rocks. Many of these offshore islands are part of the Hawaii State Seabird Sanctuary System. These sanctuaries protect seabirds, Hawaiian Monk seals, migrating shorebirds, and native coastal vegetation. These small sanctuary areas represent the last vestiges of a once widespread coastal ecosystem that included the coastlines of all the main Hawaiian Islands. Hawaiian seabirds today are subject to a number of threats to their survival, including predation by introduced mammals, habitat loss and degradation, and human impacts by people trespassing in seabird nesting areas.

The following Offshore Islet Seabird Sanctuaries are covered in this project:
Kaohikaipu Islet, Kekepa Islet, Manana Island, Moku Manu Islets, Mokolea Rock Islet, Kihewamoku Islet, Kukuihoolua Islet, Mokualai Islet, Pulemoku Islet, Mokuauia Islet, Mokulua Islets, Popoia, and Kapapa Island.
