The wetlands were formed by severe land subsidence caused by excessive groundwater extraction for aquaculture.
The Chenglong Wetlands International Environmental Art Project has been running annually since 2010.
The project invites artists to live within the community, encouraging collaboration with local villagers.
Over 100 species of birds have been recorded in the wetlands, making it a hotspot for ornithologists.
Many of the sculptures are constructed from sustainable, locally sourced materials like bamboo, driftwood, and rope.
The area is designated as a protected environmental education center by the Forestry Bureau of Taiwan.
Seawater enters the wetlands during high tides and storm surges, constantly reshaping the environment.
The project has been credited with revitalizing the local economy by increasing eco-tourism in Kouhu.
Local volunteers and students are active partners in the maintenance of the art installations.
Chenglong Wetlands is a restored coastal marshland in Kouhu Township, Yunlin, characterized by land subsidence that transformed former farmlands into a diverse aquatic ecosystem. The site hosts an annual environmental art project where international and local artists install large-scale natural sculptures that interact with the tidal landscape. These installations are designed to decay naturally, reflecting the themes of climate change and environmental adaptation. The area serves as a critical stopover for migratory birds, particularly black-faced spoonbills and various shorebirds. Wooden boardwalks provide access for birdwatching while minimizing human impact on the mudflats. The site demonstrates a successful model of community-driven land management in response to seawater intrusion. Water levels fluctuate significantly throughout the year, altering the visibility of artistic works and bird habitats. The ecosystem includes mangroves and various brackish-water flora adapted to the coastal conditions.
The main wooden boardwalks at sunset, which frame the artistic sculptures against the reflective water surface.
Bring binoculars as the wetlands are expansive and birds are often distant from the boardwalk.
Use insect repellent, as mosquitoes and midges are common in the marshy environment.
Check the local tide schedule before visiting, as high tide can submerge parts of the lower trails.
Visiting during intense midday sun, as there is almost no natural shade along the open wetland paths.
Stay strictly on designated boardwalks to protect fragile mudflat ecosystems and refrain from feeding wildlife.
