[1] The eastern hoolock gibbon is a forest-dwelling primate that prefers a continuous canopy, which makes them vulnerable to loss of habitat.

[1] The eastern hoolock gibbon has been found in tropical environments that experience monsoon rains and have cool, dry winters.

[6] The primary threat facing this species is habitat loss and degradation due to human activities, such as logging, mining, construction, and agriculture.

[6] In Myanmar, the major threat stems from the effects of commercial logging, and are subject to competition with humans for resources within the Hukaung Valley Tiger Reserve.

[1] India has also made killing or capturing the eastern hoolock gibbon illegal, but has few resources to be able to enforce the laws, thus is more focused on protecting larger mammals.
