Viet Nam’s Phong Nha-Ke Bang National Park, a World Heritage site originally inscribed for its geological values in 2003, has been extended and now includes protection for ecological and biodiversity values. Located in the Annamite ecoregion hotspot, the extended area is home to globally threatened species, including large mammals such as the Clouded Leopard, the Large-antlered Muntjac and the critically endangered Saola. The park is of particular importance for the conservation of endangered primates, such as the Red-shanked Douc Langur and the Southern White-cheeked Gibbon.
