White-cheeked gibbons are critically endangered. Their numbers have declined by 80 percent or more over the past 45 years, primarily due to habitat loss and poaching.

One of the most serious threats to gibbon viability is the unsustainable practice of timber extraction in Indonesia and southeast Asia. Habitat destruction and the subsequent degradation, either from commercial timber harvesting or conversion of land to agriculture (particularly palm oil), poses a very serious threat to these arboreal apes. Moreover, the illegal pet trade is booming in Southeast Asia and infant apes are very popular pets. 

The Association of Zoos and Aquariums Ape Taxon Advisory Group (AZA Ape TAG) has supported conservation initiatives such as anti-poaching patrols and law enforcement, additional research and support from zoos, improved management of protected areas and support of sanctuaries, and increased community involvement to help protect apes.
