The UNESCO World Heritage Committee approved the expansion of South Korea's "Getbol" tidal flats on Saturday, July 24 [1].

The decision broadens the international protection of these coastal ecosystems and recognizes their critical biodiversity value. By enlarging the protected footprint, South Korea aims to secure a more comprehensive shield for the wetlands' unique biological networks [1, 4].

This Phase II expansion adds four coastal wetlands to the existing World Heritage List [1]. The newly inscribed sites include Seosan in South Chungcheong Province, as well as Goheung, Muan, and Yeosu in South Jeolla Province [1, 2].

According to data from the expansion, the move increases the total World Heritage footprint of the Korean tidal flats by 22 percent [4]. The committee's decision, which was announced on July 25, follows a rigorous evaluation of the sites' ecological significance [1, 3].

These tidal flats serve as vital habitats for numerous migratory birds and marine species. The addition of the four sites ensures that a larger portion of the coastline is managed under strict UNESCO guidelines to prevent habitat loss and environmental degradation [4, 5].

Local officials and conservationists have long advocated for the inclusion of these specific regions to create a more contiguous protected area. The expansion allows for a more integrated approach to monitoring the health of the Getbol ecosystem across different provinces [1, 3].

“The move increases the total World Heritage footprint of the Korean tidal flats by 22 percent.”

The expansion of the Getbol tidal flats signals a shift toward landscape-scale conservation in South Korea. By increasing the protected area by 22 percent, the government moves beyond isolated pockets of preservation to a broader ecological corridor. This is particularly significant for migratory bird patterns, as it provides a larger, legally protected network of feeding and resting grounds across multiple provinces.
