Site description (2001 baseline)
Extent of this site: North from the Jishui River; south to the Jiangjun River; the eastern border is Provincial Highway 17, and the western border is the western edge of the sand flats of Wangyie Harbor. Beimen is about 30 km north of Tainan City and is a coastal wetland. The terrestrial landscape of this area consists mainly of salt fields as well as aquaculture ponds, scattered among which are several fishing villages. Within the west side of this area and the sand flats of the Wangyie Harbor is a lagoon where the fisheries are abundant. In the northeastern portion of the lagoon, there’s a mud swamp with an area of about 50 ha where the largest pure stand of Black Mangrove in Taiwan is situated. However, due to the human activities, currently there are only about 10 ha of the Black Mangrove forest and there’s need of urgent action to conserve this area.
