The national park, extended in 2008, lies on a high mountain ridge that runs west-east from the Laotian border to the East Sea at the Hai Van pass. This ridge interrupts the coastal plain of Vietnam, and, therefore, forms a biogeographical boundary between the faunas and floras of northern and southern Vietnam. More than 1400 species of plants, including many rare ferns and orchids, have been discovered here, representing a fifth of the flora of Vietnam. There are 132 mammals found in Bach Ma, three of which were only discovered in the 1990s: the antelope-like saola, Truong Son muntjac and the giant muntjac. Nine species of primates are also present, including small numbers of the rare red-shanked Douc langur. It’s hoped wild elephants will return from Laos.
