Apart from temples and pavilions, on the vast Lianchihan scenic spot also is the Chouchai Wetland Park. Once zoned as a city park, the 10-hectare eco-friendly Chouchai Wetland is a restoration wetland brought out by the urges of Wetlands Taiwan. A 5-year Jacanas Coming Home project began in May of 2003 on this freshwater wetland, as well as efforts to rehabilitate aquatic plants and vegetables, working to convert the area into an ecological germplasma bank in the Zuoying District. Feasibility studies for an aquatic park and explication & educational facilities on this site are currently underway too.

The Jacanas returned to the Chouchai Wetland at the end of 2004. Now more than 65 species of birds and assortments of aquatic plants and varieties of frogs are found here as well.
