Getbol (Korean: 갯벌) are mudflats, or tidal flats, coastal sedimentary systems. They are important habitats for different types of organisms, including migrating birds and marine fauna such as clams, crabs, octopuses, and snails. In 2021, four getbol sites in South Korea were listed as a UNESCO World Heritage Site due to their outstanding natural properties. Each of these sites represent a different type of getbol (estuarine type, open embayed type, archipelago type, and semi-enclosed type).[1]

Description

The four getbol sites that are listed are the Seocheon Getbol, Gochang Getbol, Shinan Getbol and Boseong-Suncheon Getbol. Three sites are located on Korea's western coast while the Boseong-Suncheon Getbol is located on the southern coast.

IUCN Red List species recorded as visitors, including the critically endangered spoon-billed sandpiper.[2]
Furthermore, 375 species of benthic diatoms, 118 waterbirds, 857 macrobenthos, 152 marine macroalgae, 47 endemic and 5 endangered marine invertebrate species have been recorded in the protected areas.[2]

The tidal flats developed after the

Last glacial maximum, in an interplay of rivers depositing the sediments and their dispersal by tidal currents, wave action, and wind-induced currents. They formed especially in the estuaries of large rivers and in the island coasts. As a result of monsoon climate, erosion and chemical weathering in the coast is taking place in winter while the deposition of sediment is taking place in summer.[2]

Threats

All four sites are strictly managed as Wetland Protected Area (WPA) under the Wetlands Conservation Act. Still, there are some risks that are posed to the environment by activities such as dredging of port and sea lanes, construction of land-to-island and island-to-island bridges, development of offshore wind-power generation, mining of marine aggregates, introduction of harmful or marine ecosystem disturbing species, and fishing activities of locals. The most detrimental activity is land reclamation, but such actions are strictly banned in the World Heritage Sites.[2] Possible environmental pressures include marine and coastal pollution, climate change, coastal erosion, and oil spills.[2]
