Site details
Site description: Tien Hai Nature Reserve is bordered by the Red River (also called Ba Lat River) to the south, the Lan river to the north and the main sea dike to the west. There are two sandy islands within the nature reserve: Vanh island, which covers 2000 ha and Thu Island, which covers 50 ha. Thu island is situated 4 km from the main land and the intervening intertidal area comprises sand-flats. Vanh island is separated from the mainland by a deep-water channel, the banks of which are covered by mangrove, most of which is included within aquacultural ponds. There is another extensive area of aquacultural ponds on the north bank of the Red River.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas) The site has been reviewed and re-confirmed as a KBA in the process of compiling the revised 2011 CEPF Ecosystem Profile for the Indo-Burma Hotspot.
Habitats
Summary of habitats in KBA: The site supports 12 habitat types, of which the most important are sand dune, reedbed and mangrove. In addition, the intertidal mudflats are an important habitat for feeding shorebirds.
