Although many species are threatened by hunting or resource extraction from indigenous human communities, traditional ecological knowledge (TEK) of local communities has the potential to support the management and conservation of natural resources and wildlife. The newly described skywalker hoolock gibbon (Hoolock tian xing) is found on the border of China and Myanmar, and a large proportion of the remaining population in China occurs outside nature reserves. We surveyed this species across its range in China and interviewed 622 people in 99 villages to evaluate the relationship between gibbon status and TEK of local communities. The total confirmed population was estimated to be less than 150 individuals. Gibbon subpopulations appear to have remained stable from 2009 to 2017 both within and outside nature reserves. Sociological and environmental correlates of gibbon survival outside the reserve were: (1) more Lisu than Han people present in villages; (2) greater forest cover; (3) greater distance from county towns; (4) existence of traditional taboos on hunting gibbons; and (5) higher dependency on forest resources by villagers. Interviewees living closer to surviving gibbon populations were more knowledgeable about gibbons, although interviewees living more than 25 km away also knew more about gibbons. Formal education level was also correlated with better knowledge of gibbons, and men were better informed about gibbons than women. TEK appears to limit the poaching of gibbons, thus contributing to their survival. The persistence of gibbons outside nature reserves may depend on incorporating TEK within community-based conservation strategies.
