Western Lowland Gorilla

Critically endangered

Gorilla gorilla ssp. Gorilla

Description:

The western lowland gorilla is the smallest subspecies of gorilla but still has exceptional size and strength. Western gorillas are generally smaller than their eastern cousins with shorter hair and longer arms. They tend to be lighter in colour and have a reddish chest and crest adorning their heads. They can climb trees but spend much of their time on the ground, and build nests to sleep in, mostly on the ground, but occasionally in the lower branches of trees.

Threats

Hunting
Disease
Habitat protection

Illegal poaching remains the largest threat to this species and mostly comes in the form of hunting for bushmeat. The second major driver for western lowland gorilla decline is infectious disease. Habitat loss is also a major threat to western gorillas. As oil-palm plantations in Asia reach capacity, Africa is becoming the new frontier for this crop, resulting in habitat disturbance and forest resource extraction.

 

Conservation

58% of Western Lowland Gorillas and 78% of their range are unprotected and highly vulnerable to poachers. OELO Gabon protect their forest home in Gabon.

Did you know?

Just like humans, western lowland gorillas have unique fingerprints. Each individual has a distinct pattern of ridges and furrows on their fingertips, which can be used for identification and tracking in research and conservation efforts.

Western lowland gorillas use a variety of vocalisations to communicate, but one of the more unusual aspects of their communication is their ability to produce “drumming” sounds.

Western lowland gorillas exhibit seasonal changes in their behavior. This behaviour helps them conserve energy and adapt to changing environmental conditions.

They occasionally eat insects and small invertebrates, which adds some protein to their diet.
