Suncheonman Bay's reed field covers a total area of approximately 495,867 ㎡, encompassing the regions of Gyoryang-dong and Daedae-dong in Suncheon as well as Haeryong-myeon's Jungheung-ri, Haechang-ri, and Seonhak-ri. The reed field starts from the confluence of Dongcheon and Isacheon Streams, and stretches along both sides of the stream for approximately 3 kilometers until it reaches the main reed colony at Suncheonman Bay. The reed fields in Suncheonman Bay are thickly covered with reeds taller than a full-grown man. It is the biggest colony of reeds in Korea. The scene of the entire field swaying in the wind is like watching waves on the sea. Suncheonman Bay Wetland Reserve is a natural habitat for birds of over 140 species, including migratory and endangered bird species such as the hooded crane, white-naped crane, Oriental White Stork, black-faced spoonbill, Eurasian Oystercatcher as well as birds designated as natural treasures.
