Gochang-gun has been promoting various activities for the conservation and wise use of wetlands together with local residents. Residents are actively restoring and managing wetlands, promoting wetlands and raising awareness of wetland conservation through the World Wetlands Day campaign, firefly eco-tourism, wetland restoration projects, removal of wetland invasive plants, resident capacity building education, and wetland school operation.

In particular, Gochang-gun is consistently promoting wetland restoration and conservation activities in cooperation with local governments and residents in the Gochang Tidal Flat and Ungok Wetland, which have been designated as Ramsar wetlands.

In the Gochang Tidal Flat, since 2010, 94ha of abandoned embanked fish arms have been demolished and seawater has been flowing to restore the tidal flat, thereby expanding the habitat of tidal flat organisms and contributing to increasing biodiversity. Currently, Gochang Tidal Flat is home to 80 species of water birds including endangered species such as storks, black-headed waders, and crabs, approximately 250 species of large benthic organisms, and approximately 190 species of benthic diatoms.

Ungok Wetland, an inland wetland, is an exemplary case where residents have taken the lead in wetland restoration. Since 2016, residents of the wetland village have been restoring long-abandoned farmland into wetlands using traditional levee restoration methods. In addition, they thoroughly monitor each year and repair levees that have collapsed due to heavy rain or typhoons, and with the know-how accumulated through many years of experience, they provide consulting services not only for wetland restoration in Ungok Wetland but also for restoration projects in other regions.

Thanks to these efforts by residents and local governments, soil moisture content has increased after wetland restoration, and the water that had been depleted due to past deforestation has been revived. In addition, the population of snails, salamander eggs, and northern tree frogs has increased.

Above all, the population and distribution area of fireflies, the representative species of Ungok Wetland, are visibly increasing every year. Gochang-gun utilizes this to operate a firefly eco-tour program with residents every June and September, and it has become a representative ecological experience program in Ungok Wetland.

In addition, Gochang-gun is currently working with residents to promote the Gochang Tidal Flat Vegetation Restoration Project, establish the Tidal Flat World Heritage Center, restore wetland organisms and habitats in the Ungok Wetland, and establish a wetland center, and is striving to continuously preserve and expand wetlands.
