The wetland is located in Zengwun Estuary in Tainan City. It borders Guosheng Lighthouse (Cigu Lighthouse), Nanti Levee, Haipu Levee and Jiukuaicu Levee on the north; Chingcaolun Levee of the south bank of Zengwun River on the south; Xiti Levee and Provincial Highway 17 (Guoxin Bridge) on the east; 6-meter isobaths off the coast on the west.

The wetland is located in the coastal plain (alluvium) in western Tainan. It forms a vast intertidal zone with the elevated coastline. The flat continental shelf is an ideal fish habitat and where the fishing industry could thrive. The hydrological system includes Zengwun River, Dachao and Zhongchao (Liukong Wharf Drainage Ditch). Mud mixed with organic nutrients is brought from upstream Zengwun River to the estuary, allowing plankton and benthic animals to flourish in the ocean, and creating an ideal habitat for migratory birds.

The sandy soil at Zengwun Estuary is populated with plants that thrive in this environment. Saltwater couch and beach morning glory are the dominant species. Black mangrove is the majority in the mangrove forest, followed by four-petaled mangrove. They are distributed mostly along the levee on the reclaimed land.
Survey indicates that 46 bird species are found in the Black-faced Spoonbill Reserve, including 12 protected species. Most are small mammals, such as the endemic Coxing's white-bellied rat and the protected species, masked palm civet. In addition, the protected finless porpoise and Indo-Pacific humpbacked dolphin have also been spotted here. Amphibians in the area include the protected species, Elaphe.
There are 205 species of shellfish in this area. Oyster and Asian hard clam from the ocean are key food products with economic values.
