Dadohae is an island group and national park region in the southwestern coastal zone of the Korean Peninsula, comprising numerous islets, archipelagos, and seascapes noted for complex coastlines, marine passages, and cultural heritage. The area occupies a strategic maritime position adjacent to Jeju Island, Geoje, Jindo County, Mokpo, and Yeosu, and it has long been a focus for navigation, fishing, and conservation within South Korea.

Etymology

The name derives from historical Korean maritime nomenclature used during the Joseon Dynasty and earlier Goryeo records, echoing terminology found in maps produced by cartographers associated with the Korean Empire and referenced in logs of Admiral Yi Sun-sin, Jeong Ji-hae, and other seafarers. Colonial-era charts produced under Empire of Japan administration and post-liberation surveys by the United States Army Military Government in Korea and the Republic of Korea Navy influenced modern standardized Korean place names adopted by the National Geographic Information Institute and recorded in documents from the Ministry of Oceans and Fisheries and the Cultural Heritage Administration.

Geography

The archipelago lies within the coastal waters off South Jeolla Province and features tidal flats, rocky shorelines, and narrow channels that parallel routes used by vessels traveling between Busan, Incheon, Sokcho, and southern ports such as Mokpo and Yeosu. Major nearby geographic references include Sinan County, Wando County, Geoje Island, Namhae, and the Korean Strait. The landscape displays influences from Yellow Sea tidal regimes, seasonal currents tied to the East China Sea and the Kuroshio Current, and seismic and sedimentary processes recorded by the Korean Peninsula coastal geomorphology research community and institutions like Sejong University and Pukyong National University.

History

Human engagement with the islands is attested in archaeological finds linked to the Neolithic and Three Kingdoms of Korea periods, with subsequent mentions in records from the Goryeo and Joseon Dynasty administrations. The archipelago appeared in maritime dispatches related to the Imjin War and the naval campaigns of Admiral Yi Sun-sin, and later in the cartographic surveys by Kim Jeong-ho and maps used by officials of the Korean Empire. During the Japanese occupation of Korea, the islands were incorporated into imperial administrative schemes, and after 1945 they featured in postwar maritime boundary discussions involving the Republic of Korea, the People's Republic of China, and the United States. Modern development, including ports and ferry terminals, has connected the region to economic centers such as Seoul, Gwangju, and Busan while prompting involvement from agencies like the Ministry of Land, Infrastructure and Transport and the Ministry of Oceans and Fisheries.

Ecology and Biodiversity

The islands host habitats for species monitored by the Korean Peninsula Environmental Observatory, with tidal flats supporting migratory birds tracked by organizations such as BirdLife International, Wetlands International, and researchers from Korea University and Chonnam National University. Flora and fauna include coastal seaweeds and fish species studied by Inha University and marine biologists collaborating with the National Institute of Biological Resources and the Korea Marine Environment Management Corporation. Endangered and protected taxa recorded in the region have been subjects of conservation action by the Ministry of Environment and initiatives associated with the Ramsar Convention and the Convention on Biological Diversity. Research partnerships have involved institutions such as the Korean Ocean Research and Development Institute and international programs with universities like The University of Tokyo and Shanghai Ocean University.

Economy and Human Activity

Local economies center on fisheries linked to companies and cooperatives represented by the Korean Federation of Fisheries Cooperatives, aquaculture ventures supplying markets in Seoul and Busan, and shipping services connecting ports like Mokpo and Yeosu. Historical industries included salt farming and kelp harvesting tied to trade routes frequented by merchants from Gyeongju and Busan. Infrastructure projects overseen by the Korea Expressway Corporation and regional governments have involved ferry services, harbors, and tourism facilities, while scholarly economic analyses from Korea Development Institute and Korea Maritime Institute assess sustainability, demographic change, and the impact of national policies such as those promoted by the Ministry of Trade, Industry and Energy.

Culture and Tourism

Archipelagic communities preserve intangible heritage, including boat-building traditions documented by the Cultural Heritage Administration and maritime folk practices celebrated in festivals promoted by municipal governments in Sinan County and Jindo County. Tourist attractions draw visitors from Seoul, Busan, and international travelers arriving via Incheon International Airport and Gimpo International Airport, with excursions organized by tour operators based in Mokpo and Yeosu. Nearby cultural sites and routes connect to historical locations like Gwangju, Gyeongju, and Jeonju, and to contemporary arts initiatives involving institutions such as the Asia Culture Center and the National Museum of Korea.

Conservation and Protected Areas

Significant portions fall under protections administered by the Korea National Park Service and the Ministry of Environment, including designations aligned with international frameworks like the Ramsar Convention and collaborations with UNESCO-affiliated programs. Conservation planning has engaged NGOs such as the Korean Federation for Environmental Movements and research bodies including the National Institute of Ecology and the Korea Institute of Ocean Science & Technology, addressing pressures from commercial fisheries regulated via policies shaped by the Ministry of Oceans and Fisheries and the Korean Coast Guard. Ongoing conservation actions intersect with regional development policies involving the Ministry of Land, Infrastructure and Transport and local governments in South Jeolla Province.
