Site description This IBA comprises Bach Ma National Park, situated towards the southern end of the Annamite mountains. The national park lies on a high mountain ridge that runs west-east from the Laotian border to the East Sea at the Hai Van pass. Bach Ma National Park is probably the wettest place in Vietnam. The Bach Ma area supports a wide range of habitat types, from coastal lagoon to montane forest. Bach Ma is situated at a biogeographic boundary between northern and southern Vietnam, and between the Annamite mountains and the coastal plain.
Key Biodiversity The national park lies at the southern extent of the Annamese Lowland Endemic Bird Area (EBA), and is known to support five of the restricted-range species found in this EBA, including Edwards's Pheasant Lophura edwardsi and Crested Argus Rheinardia ocellata. Also of conservation importance, Bach Ma National Park supports an endemic subspecies of Silver Pheasant Lophura nycthemera beli.
Non-bird biodiversity: The following species are listed in the investment plan as occurring at the site: Pygmy Loris Nycticebus pygmaeus, Rhesus Macaque Macaca mulatta, Long-tailed Macaque Macaca fascicularis, Stump-tailed Macaque Macaca arctoides, Red-shanked Douc Langur Pygathrix nemaeus nemaeus and Yellow-cheeked Crested or White-cheeked Crested Gibbon Nomascus gabrielle/ leucogenys. However, the source of the data is not clear, and therefore these records should be considered to be provisional.In addition, Giant Muntjac Megamuntiacus vuquangensis, Southern Serow Naemorhedus sumatraensis and Saola Pseudoryx nghetinhensis are also listed in the investment plan as occurring at the site. Again, the source of the data is not clear, and so therefore these records should also be considered to be provisional. A number of threatened conifer species are also provisionally listed for the site.

nature conservation and research
Protection status Bach Ma National Park also has a wider significance as a link in the last chain of contiguous natural forest between the Laotian border and the East Sea. Bach Ma will form part of the planned Green Corridor landscape-level conservation project.
