Scientists of LVDI International and GreenViet recently published an article in the Vietnamese Journal of Primatology (Bui, Tan, Nguyen et al 2019_ VJP) highlighting results from the first inventory of primate species in the new expansion areas of Ba Na-Nui Chua Nature Reserve (BNNC) located in Danang, Vietnam. Using mixed methodologies, our team confirmed the presence of at least six primate species. The most exciting discoveries included the presence of the endangered northern yellow-cheeked crested gibbon (Nomascus annamensis) and red-shanked douc (Pygathrix nemaeus). The rich assemblage of primate and other wildlife species found in the nature reserve provided the necessary data to convince the Vietnamese government to develop a long-range conservation plan for the central Annamite region.
