The International Union for Conservation of Nature has recommended four additional South Korean tidal flats for inscription on the UNESCO World Heritage List [1].

This recommendation signals a potential expansion of South Korea's recognized natural heritage, highlighting the ecological significance of its coastal wetlands. The move could strengthen international conservation efforts for migratory birds and marine biodiversity in the region.

The recommended sites are located in Yeosu, Goheung, Muan, and Seosan [1], [2]. According to the Korea Heritage Service, the recommendation was announced June 5, 2026 [1]. These specific areas were deemed to possess outstanding ecological value and meet the rigorous natural heritage criteria established by UNESCO [1], [2].

The final decision regarding the inscription will be made during the UNESCO World Heritage Committee meeting [2]. This meeting is scheduled to take place in Busan in July 2026 [2], [3].

South Korea has previously sought to expand its World Heritage listings to protect its unique coastal environments. The current proposal focuses on the biodiversity of the southern coast, where tidal flats serve as critical habitats. The IUCN's support is a primary step toward official recognition, a process that requires a formal vote by the committee members.

Officials from the Korea Heritage Service said the sites are essential for maintaining the ecological balance of the peninsula. The recommendation follows a detailed evaluation of the sites' integrity and the management plans put in place to protect them from urban development and pollution [1].

The potential addition of these four sites would expand South Korea's footprint on the UNESCO World Heritage list, elevating the global priority of protecting its coastal ecosystems. Because the final decision occurs in Busan, the event serves as a high-profile diplomatic and environmental showcase for the country's conservation capabilities.
