The rich ecology and biodiversity of the tidal flats surrounding islands in the southwest of the country provide spawning ground for fish and contribute to macro benthic animal diversity. The site also provides food and resting grounds for waders and migratory birds that pass by this area for breeding and wintering, supporting five internationally endangered species including the Chinese Egret Egretta eulophotes, Baikal Teal Anas Formosa, Far Eastern Curlew Numenius madagascariensis, Eurasian Spoonbill Platalea leucorodia (App II CMS) and Peregrine Falcon Falco peregrines (App I CITES). Jeungdo has a long history of fisheries, and fishing in the area holds great cultural, social and traditional importance for the local people. The amphibious air-breather Goggle-eyed Goby or mudskipper (Boleophthalmus pectinirostris) has minor commercial uses, and the amphibious Shuttles hoppfish (Periophthalmus modestus) is also present. This region was part of the 'Marine Silk Road', a seaward passage for trade and cultural exchanges between China and other countries in ancient times. With sandy beaches and beautiful landscape, the site attracts many tourists, as well as students of the tidal environment. Construction of a barge dock and its facilities, along with "Nodoo" Road has hampered the sea flow. The site has a Five Year Management Plan which was established at the end of 2010.
