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.
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.
