Seocheon Tidal Flat is an open tidal flat directly linked to the ocean, its ecosystem is composed of a combination of sand and/or muddy sand flats which are very important for migratory birds and as a spawning and nursery ground for fish. Seocheon Tidal Flat supports globally threatened bird species such as the vulnerable Saunders' Gull (Larus saundersi), the critically endangered Spoon-billed sandpiper (Eurynorhynchus pygmeus) and the endangered Spotted Greenshank (Tringa guttifer). This wetland supports 1% of the population of Eurasian Oystercatcher (Haematopus ostralegus), providing an important habitat for over 3,000 individuals as a stopover site during winter and as a breeding area. There are 125 species of fish which include the River Puffer (Takifugu obscurus), Korean Rockfish (Sebastes schlegelii), and other marine life such as the Japanese eel (Anguilla japonica) and ninety-five species of macro benthic animals. Due to its wide expanse, Seocheon Tidal Flat protects the coast from typhoons, waves, and also slows down tidal current which performs an important function of transporting deposits which have been carried down the main river. Through filtration, the sediments are highly effective in flood control and also purify nutrient and metallic pollutants discharged from farms and sewage stations near the site. Locals take advantage of the farming tracts and paddy fields in surrounding areas. Various marine food can be harvested including shellfish such as clams (Ruditapes philippinarum and Dongjuk, Mactra veneriformis), octopus (Octopus membranaceus) and crustaceans such as the Korean Shrimp (Penaeus chinensis). Threats to the area include extraction of living organisms from the tidal flat, and increased pollution in the surrounding areas. The Division of Fisheries and Ocean Division (Chungcheongnam-do province) is directly responsible for managing this diverse and culturally rich wetland
