Wetlands, including "swamps," "marshes" and "bogs', is an area of transition connecting sea and land.

It is sometimes referred to as the "swirl of life" or the "lungs of the earth" because of the rich abundance of life filling it.

The Suncheon Bay wetland expands over the area where the Dong-cheon and Isa-cheon rivers meet. These two rivers contribute all the components needed to form the wetland. A recent increase in their flowing-slope has added a current that is increasing the development of the wetland.

As a saltwater wetland, Suncheon Bay is extremely unique to the Korean Peninsula and is therefore named as a preservation area in light of ecological development and protection.

A bed of reeds and suede japonica provides a habitat for migratory birds. This results in a beautiful sight that charms tourists and lures them to experience the wetland.
