Several urban areas and popular tourist destinations have suffered from pollution from the land, significant fishing pressure, recreational overuse, and alien species. Despite these pressures, many coral reefs in Hawai'i remain in fair to good condition, especially remote reefs; Most MPAs have proven to be highly effective in conserving biodiversity and fisheries resources. MPA size, habitat quality, and level of protection are the most important success factors, but several MPAs are too small to have significant effects outside their boundaries; Community-based management has been effective at several locations in Hawai'i and expansion of these efforts is being encouraged; Continued invasion and degradation of new habitats by alien species remains one of the most pressing threats to reefs in Hawai'i; The Papahanaumokuakea Marine National Monument (PMNM) is the largest fully protected marine conservation area in the world, with a unique predator-dominated trophic structure, many endemic species, and many threatened and endangered species. This is an important global biodiversity 'hot spot'; Global impacts such as climate change (sea level rise, ocean warming and acidification) and marine debris threaten the unique ecosystem of the PMNM, and rapid international action is needed.

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.
