The Yellow Sea Ecological Region is a marine area located between the eastern coast of China and the Korean Peninsula. It is characterized by shallow waters, rich biodiversity, and significant fisheries. The region is influenced by the Yellow Sea and Bohai Sea, which support various habitats, including wetlands and estuaries. This ecological region is vital for migratory birds and marine species, serving as a crucial stopover for birds along the East Asia-Australasia Flyway. However, it faces environmental challenges such as pollution, habitat loss, and overfishing, which threaten its ecological balance and biodiversity.
