The Yongan Wetland, one of the major salt pans in southern Taiwan, was originally called the Wushulin Salt Pan. Hundreds of years ago, local people made a living by producing and selling salt. At the beginning of the Japanese occupation period, people were encouraged to invest in building salt pans in order to increase salt production. In 1908, led by Chang Zou-zhou, people applied for the establishment of salt pans covering hundreds of hectares in order to use inland sea water from Singda Harbor to evaporate brine for salt. When Chen Jhong-He became the leader, he founded Wushulin Salt Production Company. The baroque-style office building of the Wushulin Salt Production Company preserved in the wetland is characterized by gables decorated with vortex and leaf emblems. The office building was built by Chen Jhong-He.
Yongan Salt Pan ceased functioning and was transferred to Taiwan Power Company (hereinafter referred to as Taipower). Taipower originally planned to build ponds to store the coal ashes of Hsinta Power Plant. However, compensation issues between the salt producers and Taipower has remained unsolved. Coal ashes can be recycled for other uses, but Taipower did not fill coal ashes into this salt pan. Therefore, there are various mangroves and water birds in this abandoned salt pan at the low-lying coastal area. The Yongan Wetland has gradually become a habitat and a major feeding ground for migratory birds. There have been 168 recorded species over the years, in total. In 1999, the Yongan Wetland was evaluated by BirdLife International as an Important Bird Area (IBA).
Since the merger of Kaohsiung City and County, Mayor Chen has paid much attention to ecological preservation and landscape constructions. She deeply felt that Yongan Wetland should be managed well, so the government negotiated with Taipower to provide the wetland. The Maintenance Office of the Public Works Bureau proposed the budget for early plans and distributed the detailed cost of construction, 26.677 millions. By the means of low-development plans and gradual reduction, we observed the species and the environment, and focused on reproduction, while paying much attention to ecological education and tourism. Also, the ecological education and the function of tourism not only covered the whole wetland, but also educated citizens. Citizens can personally experience the beauty of wetlands, tourism development, conservation of resources and our demand for mutual benefits and interdependence with environmental protection.
