One research was focused on Niaosung Wetland Park(NWP). The Niaosung wetland park was developed from the sinking pool of the Cheng Chin Lake Branch, Taiwan Water Supply Company. The site was originally designed to precipitate sediments from wastewater exhausting from Cheng Chin Lake Water Treatment Plant. The sinking pool gradually became a small-scale artificial wetland by sufficient water and nutrients. NWP was launching in September, 2000, which have seen working more than four years. Although the construction methods of NWP were disputable and destroyed existing ecosystem, NWP was still tended slowly to nature after recovering naturally for four years. Actually, It is difficult to manage NWP for the reason of that it is located in Grant Kaohsiung municipal area.
