Chenglong Wetlands

Chenglong Wetlands () is a wetland in Kouhu Township, Yunlin County, Taiwan.
History.
The wetland was formed due to the low altitude of the lower Hukou Village of Kouhu Township and the overuse of groundwater over the years. Those factors contributed to the land subsidence of the area which make it prone to flooding. More sea water encroachment are also brought by the frequent typhoon happening in Taiwan, which eventually turned the area into wetland.
Geology.
The wetland spans over an area of 50 hectares.
