The Sihcao Wetlands (四草) are a protected ecological environment in Tainan, Taiwan. They were set aside in 1994 by the Tainan City government and consist of approxiamtely 515 hectars.[1]
The protected area consists of mangrove swamps, salt marshes, rivers, canals and drainage ditches. It is located in Tainan City's Annan District, and consists of the area bounded by the southeastern side of the Luermen River, the southwestern side of Xi-Bin Road, and the northern side of the Yan-Shui River.[1]
In November 2004, the Sihcao Wildlife Refuge(四草野生動物保護區) was created to further protect the area, especially from possible encroachment from the nearby Tainan Technology Industrial Park.[2]
On 10 December 2007, the Sihcao Wetland, along with the Zengwun Estuary Wetland (曾文溪口濕地) were listed as international wetlands under the Ramsar Convention.[2]
