From the junction of the Dong and Isa streams to the beginning of the mudflat in Suncheon Bay, it has the widest reed bed in Korea.

In autumn, reed blossoms, red turkeys, and white migratory birds make the area a popular attraction.

Suncheon Bay consists of brackish water, earth and sand, transported in by the river and accumulated over time by the tide of the sea, forming an extensive sandbar.

Due to little pollution, the area has developed salty swampy land, abounding in fresh marine products, and numerous and varied invertebrate animals and sea plants.

The extensive reedbeds form the wintering site and habitat for rare birds including the hooded crane, sea gull, white stork, black-faced spoonbill and eastern great egret.

A community of Phragmites communis forms the sides of the inner bank, which is also inhabited by zoysia sinica, Kummerowia stipulacea, Rhynchosia volubilis, and other plant life.

The Phragmites communis community extends more and more as a dominant species of Suncheon Bay, developing and forming a ring shape in several areas of the reeds.

The beginning of Suncheon Bay contains a densely spread community of Phragmites communis approximately 300,000 pyeong in size, which is more than 30 years old.

The Phragmites communis community has an outstanding purifying function and provides a productive environment for Boleophthalmus pectinirostris, which is very sensitive to pollution.

Other visiting species to the area include Grus vipio, Platalea minor, Ciconia boyciana, Falco tinnunculus interstinctus, Microsarcops cinereus, and Haematopus ostralegus osculans.

Bivalve mollusks, such as Neanthes japonica, Sinonovacula constricta, Cyclina sinensis, Megangulus venulosus, and glaucinomyachinensis, are widely spread throughout the middle and lower beaches.

Outdoor facilities include the beach experience course nearby that can be used as an ecology study course for students and the general population, in addition to overview and sunset over Suncheon Bay.

The natural ecological value of Suncheon Bay is represented by the habitation of migratory or passage birds, a measure of the productivity value of the swamp.

Numenius madagascariensis, or Far Eastern curlew, loses half of its weight during its migratory flight 4,000–5,000 km (2,500–3,100 mi) non-stop from Australia.

Summer passage birds of the Suncheon Bay area include Nycticorax nycticorax, Bubulcus ibis, Egretta garzetta, Egretta alba modesta, Ardea cinerea, Charadrius dubius curonicus, Alcedo atthis bengalensis, Motacilla cinerea robusta, Motacilla alba and Acrocephalus arundinaceus.

Oxygen discharged from the roots of Phragmites communis oxidizes soil in a resolving state, and promotes the activation and dissolution of nearby microorganisms.

The wide Phragmites communis field provides an environment for the microorganism group to inhabit so that it dissolves and disperses various types of polluting substances.

Suncheon Bay was designated as a swamp preserving area of Korea in December 2003, and it joined the international network for protection of the crane in northeastern Asia in 2004.

The Northeastern Crane Network was organized as a protection strategy of Asian and Pacific passage birds at the 6th Ramsar Convention conference in 1996.

The Ministry of Maritime Affairs and Fisheries of Korea will request registration of Suncheon Bay as a Ramsar swamp in August or September 2013.

Suncheon Bay is one of the fifth-largest tidal flats in the world, an international wetland that attracted approximately 2.8 million visitors in 2008.

The placement of the building maximizes both the picturesque views to the mountains beyond and to the river, creating a visual continuation of both the water's path and visitor's circulation.

The wooden façade is intended to minimize summer sun exposure, maximize potential winter daylight and blend in with the surrounding woodland to the north.

Framed views from the gallery through these wooden slats capture light and help set the mood for the visitor's center.
