The Tonkin Snub-nosed Monkey, Rhinopithecus avunculus, is listed as ‘CRITICALLY ENDANGERED’ on the IUCN Red List of Threatened Species™. The range of this unusual and distinctive primate has been drastically reduced, and it is now known from just five isolated locations within Vietnam.

Due to massive deforestation and intensive hunting, just 200 to 250 individuals of this species remain, and its population is highly fragmented. Although not the main target of hunters, it is still shot when encountered, and is either eaten or used in traditional medicine. Widespread forest destruction has reduced and fragmented its habitat, while the recent development of a hydroelectric project has not only caused further habitat loss, but also an influx of construction workers, resulting in an increased demand for meat and resources.

Despite legal protection, hunting and habitat loss unfortunately continue throughout the Tonkin Snub-nosed Monkey’s range. Various conservation efforts are underway, including efforts to raise local awareness, establish patrol groups, undertake further surveys and impose gun controls, but the future of this highly endangered primate still hangs in the balance.
