Site description
Extent of this site: situated in a marshy wetland area on the north side of where the Chihben River empties into the sea. It was formerly the main channel of the Chihben River, and carries the water from the Shemagan River. The current aquatic area is more than 20 ha; in addition, the scope of the site includes protection forests, sea beaches, and the Chihben Estuary. The Chihben wetlands are at an early successional stage of a marshland ecosystem. Dominant wetland plants include Phragmites communis, Typha SP., Barect Grass Leersia hexandra, Broad-leaved Bow Grass Cyrtococcum accrescens, and Armgrass Oplisrnenus compositus. Because development by the Jiedier Company has not proceeded, the sand and gravel brought by estuarine waves and tides have closed the Chihben Wetland’s outlet channel, and the wetland has begun to recover. The marsh again shows vitality; fish, molluscs, and bird species are breeding in this area. It is a surviving natural treasure on the southeast coast of Taiwan.
