SEOUL, South Korea — The Okefenokee Swamp in Georgia, a centuries-old porcelain center in eastern China and tidal flats in western South Korea were among several sites added to the World Heritage List on Saturday at a U.N. committee meeting in South Korea.

The UNESCO meetings in Busan, which continue through next Wednesday, are reviewing dozens of other nominations, including the D-Day landing beaches in France, Mount Olympus in Greece and the ancient Japanese capitals of Asuka and Fujiwara.

The Okefenokee Swamp is regarded as one of the world’s largest freshwater ecosystems, encompassing a vast network of wetlands that supports exceptional biodiversity and serves as the source of two major rivers. Its largely undisturbed peat beds preserve a 5,000-year record of environmental change, making the swamp both a globally significant natural habitat and a valuable source of information on long-term environmental change, according to a UNESCO description.

While the World Heritage designation places the Okefenokee National Wildlife Refuge alongside iconic U.S. landmarks such as the Grand Canyon, some locals have opposed the listing, fearing it would increase U.N. involvement in managing the site.

“We accept this inscription not as a finish line, but as a commitment to keep the Okefenokee wild, resilient, and thriving for generations to come,” said Kim Bednarek, executive director of the nonprofit Okefenokee Swamp Park that’s worked with the U.S. government on the refuge’s nomination package.

The committee also decided to expand the World Heritage listing of the South Korean “getbol” tidal flats with four additional coastal wetlands in Seosan, Goheung, Muan and Yeosu in the country’s west. UNESCO had previously inscribed four other South Korean tidal flats in 2021 for their biodiversity and crucial role as a stopover for migratory birds.

South Korea’s Foreign Ministry said the expanded designation of the tidal flats “reaffirms the importance of international cooperation for the conservation of the Yellow Sea ecosystem and the East Asian-Australasian Flyway,” a major migratory bird route that stretches from the Arctic through Asia to Australia and New Zealand.

Another new addition to the World Heritage List was the handicraft porcelain industry sites in China’s Jingdezhen. The sites trace the evolution of handcrafted porcelain production in China from the 10th to the 19th centuries, showcasing innovations that helped make Jingdezhen a leading center for fine porcelain, with its blue-and-white porcelain becoming a global symbol of Chinese craftsmanship, according to UNESCO.
