Site details
Site description: Tien Lang comprises the coastal zone of Tien Lang district, Van Uc estuary and Thai Binh estuary. The site supports approximately 400 ha of old growth mangrove forest, estimated to be more than 50 years old. Almost all of the old-growth mangrove at the site is enclosed within aquacultural ponds. Some of the mangrove occurs in scattered clumps, with individual trees estimated to be more than 100 years old. Between the main dyke and the trees in the Tien Lang district coast sector of the site, there is an area of grass and sedge. An area with saltmarsh and small lakes is found behind the dunes. The Thai Binh estuary sector of the site comprises the old-growth mangrove and connected intertidal flats along the Thai Binh river. An area of old-growth mangrove forest lies to the south of the Van Uc estuary, beyond which lies saltmarsh and a Castuarina equisetifolia plantation.
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.
