Okefenokee: A Major American Wetland Becomes a World Heritage Site
Okefenokee National Wildlife Refuge, a vast freshwater peatland in the south-eastern United States, has joined the UNESCO World Heritage List for its biodiversity, ecological processes and carbon-storage role.
Okefenokee Swamp in the south-eastern United States has been inscribed on the UNESCO World Heritage List during the 48th session of the World Heritage Committee, held in Busan, South Korea, in July 2026.
The designation covers Okefenokee National Wildlife Refuge, a vast wetland complex located mainly in Georgia and extending into north-eastern Florida.
According to UNESCO, the site is the largest low-altitude freshwater peatland in the subtropical zone and one of the best-preserved ecosystems on the North American coastal plain.
The refuge covers about 164,565 hectares of marshes, forests, savannahs and peatlands shaped by alternating rain, drought and natural fire.
A mosaic of habitats
856 | recorded plant species 238 | bird species 90 | reptile and amphibian species 48 | mammal species
The refuge supports a large population of American alligators and provides habitat or a stopover for many migratory birds.
It also contains pond-pine savannahs, a habitat once widespread in the south-eastern United States but of which less than 3% is thought to remain, supporting several endemic plant species.
Its peat-rich soils store carbon accumulated over long periods. As long as they remain wet and intact, the carbon stays trapped; prolonged drying or very intense fires can cause it to be released.
The designation therefore recognises both the role of major wetlands in water regulation and carbon storage and the value of the landscape itself.
What the status changes, and what it does not
No. The designation recognises “outstanding universal value” and commits the country to preserving the characteristics that justified it, but does not automatically create new federal or local regulations. UNESCO does not take control of the refuge, which remains managed by the relevant US authorities. International recognition may increase scrutiny of extraction projects discussed nearby, but it does not prohibit them. Authorisation continues to depend on national and local legal and environmental procedures.
The Associated Press reports that this issue had caused concern in some neighbouring communities, where opponents feared direct United Nations intervention.
The International Union for Conservation of Nature, UNESCO's advisory body for natural sites, recommended inscription because of the integrity of the hydrological system and the diversity of habitats.
The site was selected under two natural criteria: ongoing ecological and biological processes, and important habitats for conserving biological diversity.
Conservation will depend above all on long-term measures: maintaining water flows, preventing pollution, managing fire appropriately and regulating activities around the refuge.
