Eastern Lowland Gorillas
The eastern lowland gorillas found only in the Democratic Republic of Congo are also known as the Grauer's gorillas are the largest of the four gorilla subspecies distinguished form other gorillas by their large hands, short muzzle and stocky body. In spite of their size, they feed on fruit and herbaceous foods. They make their homes in the lowland tropical rainforests of the Democratic Republic of Congo. Due to many years of civil unrest in the the Democratic Republic of Congo, the toll on eastern lowland gorillas and mountain gorillas has been enormous and throughout the unrest, the gorillas have been vulnerable to poaching. Kahuzi Biega National Park is the home to the largest population of protected eastern lowland gorillas. At this park rebels invaded and set up illegal mines but with the help of conservation agencies, the park authorities are regaining back control of the land. Maiko National Park also has some eastern lowland gorillas.
The Wildlife Conservation Society and other partners documented a disturbing drop in Grauer's gorilla numbers, from a projected 17,000 in 1995 to just 3,800 individuals. A current follow-up study led to this estimate being revised upwards to 6,800, but this is still less than half the number recorded a quarter of a century earlier.
Grauer's Gorilla Facts
- Grauer's gorillas are, on average, the largest of all gorilla subspecies. Males can weigh up to 250 kilos and reach two meters tall when standing
- Predominantly herbivorous and eat mainly plant matter (including fruit and bamboo), but sometimes they eat insects.
- Unlike other gorilla subspecies, if a group feels endangered, the whole family will stand its ground instead of fleeing.
- Grauer's gorilla lives in family groups and they are highly sociable animals, on average comprising between two to 30 individuals.
Due to high demand for bush meat, growing human population, civil unrest from armed groups, mining, logging and habitat loss to agriculture in the Democratic Republic of Congo, the Grauer gorillas are facing extinction and are declining in number. The Fauna and Flora International organization is working with local communities and authorities to conserve the eastern lowland gorillas and their habitat at in areas outisude the national parks through training and equipping community rangers. They also conduct patrols to monitor and record the presence of gorilla groups and other species like chimpanzees, peafowl and Okapis. Trained community ranges remove snares that can cause danger to the gorillas.
