Site description Dat Mui Nature Reserve is situated at the southernmost tip of Vietnam. The site was originally covered in natural mangrove forest dominated by Rhizophora apiculata, but the vast majority was destroyed during the Second Indochina War and, later, by conversion to aquaculteral ponds and agricultural land. Most of the aquacultural ponds have been abandoned, and now support extensive areas of recolonising mangrove forest. There are extensive mudflats, which are also being colonised naturally by mangrove. The site is continually growing due to accretion rates along the coastline of up to 50 m per year in some places. To the north, Dat Mui Nature Reserve is contiguous with Bai Boi Coastal Protection Forest, and together these two areas comprise an important area of intertidal mudflats and mangrove forest for migratory waterbirds.

Protection status Initially an area of 4461 ha was proposed for the Dat Mui Nature Reserve. The site managed by the Forestry Protection Department (FPD) covers 7239 ha, with 4388 ha described as Special-use Forest by the site staff. However, they only treat 1717 ha of this as 'strictly protected' .
