Conservation
The black crested gibbon is listed as critically endangered on the IUCN Red List. An estimated 1300 to 2000 individuals are left in the wild. The western black crested gibbons were included on the State Forestry Bureau of China's list of 12 flagship and keystone species for biodiversity protection in 2021. While under protection, there was still a noticeable decline in population size at Wuliangshan National Nature Reserve. It was discovered that the gray langurs are suppressing the black crested gibbon's potential recovery. The gray langurs and black crested gibbons have similar diets and ranges; however, gray langurs have an advantage by having a more comprehensive dietary list, a larger group, and faster life history. The black crested gibbon inhabits the evergreen broad-leaved forests that take a long time to regenerate, making it challenging for the gibbons to connect with other groups. Ecological corridors were put in place in the Hengduan Mountain in China to help restore connections between different groups, increase overall well-being, and decrease the risk of extinction.
