French Polynesia Establishes World’s Largest Marine Protected Area

Record-Breaking Marine Protection
On 9 June 2026, President Moetai Brotherson announced that 520,000 km² of ocean surrounding the Austral and Marquesas archipelagos will receive IUCN Category 1 protection, prohibiting seabed mining, bottom trawling and industrial fishing. The declaration was made at the UN Ocean Conference.
Background & Significance
French Polynesia had already placed its entire exclusive economic zone—about the size of the European Union—under protection in 2023. Its reefs host endemic species such as the Marquesan domino damselfish and provide habitat for sharks, whales, dolphins, sea turtles and tuna spawning grounds. The territory is noted for a low-impact, well-monitored fisheries sector.
Scope, Protection Level, and Funding
The 520,000 km² core will be fully protected, while adjacent artisanal-fishing zones and two fully protected cores bring the managed area to roughly 1.08 million km². A $15 million fund from Te Moana Collective—comprising Blue Nature Alliance, Becht Foundation, Bezos Earth Fund, Blue Marine Foundation, Bloomberg Ocean Fund, Oceans 5, Pew Bertarelli Ocean Legacy and Wyss Foundation—will support a 15-to-20-year conservation trust.
Biodiversity Impact and Sustainable Fisheries
The protection safeguards endemic fish, endangered sharks, sea turtles and tuna spawning habitats. By maintaining artisanal-fishing zones, the measure aims to protect food security and cultural practices while reinforcing French Polynesia’s low-impact fisheries model.
Responses and Challenges
President Brotherson described the ocean as the source of life, culture and identity for his people and asserted ecological sovereignty in setting protection standards, while Maël Imirizaldu of the Blue Nature Alliance called the move a global-leader milestone. Industrial fishing and mining stakeholders have voiced concerns about lost access, and observers note many marine-protection targets remain unmet and enforcement of reserves often proves weak. Industrial fleets use drifting fish-aggregation devices that enter the protected zone, deep-sea mining interests eye the mineral-rich seafloor, and climate-related threats such as coral bleaching and cyclones compound the risk, making patrols of 520,000 km² a logistical hurdle.
Conflicting Reports
Conservation International reports the core as 520,000 km², while the Eastern Herald describes a managed area of roughly 1.08 million km² that includes artisanal zones and fully protected cores. Detailed data on enforcement capacity remain limited.

Next Steps
French Polynesia aims to add more artisanal zones and two fully protected reserves by year-end, raising highly protected waters to about 2.5 million km². The Te Moana Collective will continue developing a long-term financing mechanism while observers monitor enforcement of the unprecedented sanctuary.
