Listed as Endangered as, there is reason to believe the species has declined by at least 50% over the past 40 years (three generations) due primarily to hunting for pet trade and continued rates of habitat loss (mainly as a result of expanding agriculture and road building). Although there has likely been 70-80% habitat loss of primary habitat within the past 50 years within the range of the species, this species is one of the most adaptable gibbons to habitat change. Although the species occurs in numerous protected areas and retains a number of viable populations, it could in future be considered Critically Endangered due to historic habitat loss, and should be closely monitored in the future.
