Positive influence of traditional culture and socioeconomic activity on conservation: a case study from the black-and-white snub-nosed monkey (Rhinopithecus bieti) in Tibet.

Found in the Trans-Himalayas of north-west Yunnan and south-east Tibet, the black-and-white snub-nosed monkey (Rhinopithecus bieti) is one of the world's most endangered primates. A recent survey indicates that only 15 groups with 2500 individuals remain in the wild. However, the Tibetan Xiaochangdu group may be the only equilibrium group in the field since the last investigation in 1988. To evaluate the effects of traditional culture and socioeconomic activity on biodiversity conservation of R. bieti, we conducted a case study in the Honglaxueshan National Nature Reserve in southeast Tibet from June 2003 to May 2005. Interviews, direct observations, and analysis of socioeconomic data indicated major advantages to the conservation of R. bieti, which included that: 1) traditional culture mainly depended on raising livestock and collecting non-timber products rather than forest planting of Tibetan highland barley; 2) religious beliefs, against to kill any wildlife living on the sacred mountain, were mainly influenced by Tibetan Buddhism; and 3) bigger household numbers were induced by the polyandrous marriage system, which resulted in lower per capita resource consumption than smaller ones.
