The Dongzhaigang National Nature Reserve is located in Dongzhaigang Bay bordering the administrative regions of Qiongshan City and Wenchang City, in north eastern Hainan Province. The area trans-bounds the tropical and sub-tropical zones of southern China and has a correspondingly diverse transitional fauna and flora with the southern sub-tropical species dominant. The transitional climatic and hydrological conditions, specific topographic features (estuarine ecosystems) and its rich biodiversity ensure its global significance as a wetland of international importance. Its relatively large area of mangrove forest and wide inter-tidal sand and mudflats provide migratory water birds and fish with rich feeding grounds and breeding habitats.   [check]
