Status of coral reefs in the Polynesia Mana node is predominantly healthy. There are 6733 km2 of reefs scattered over 347 islands. Most (90%) are healthy, 5% have been destroyed or are at a critical stage and 5% are under threat;Reefs have been degraded around populated areas of Rarotonga (Cook Islands), Tahiti and Moorea (French Polynesia) and South Tarawa (Kiribati);Coral reefs support the livelihoods of Polynesian populations through subsistence fishing in all countries and through tourism and black pearl industries in French Polynesia and the Cook Islands; The main threats to the reefs are global warming for the remote reefs and land- based pollution for reefs near urban areas. Dynamite fishing still occurs in Wallis and Futuna;Reefs are mostly healthy in Wallis and Futuna, Tuamotu-Gambier and the Marquesas Archipelagos of French Polynesia; Reefs have largely recovered from past bleaching events in Phoenix Islands and Tarawa in Kiribati, and reefs are recovering from crown-of-thorns starfish (COTS) outbreaks in Rarotonga (Cook Islands) and from a cyclone in Niue; Reefs are facing a major COTS outbreak in the Society Archipelago of French Polynesia; and Socioeconomic assessments are now being implemented in the region, in parallel with ecological monitoring, to support coral reef management.
