What You Need to Know About The Sumatran Orangutans


Native to the island of Sumatra, this species of great ape, the Sumatran Orangutans are found in Gunung Leuser National Park, which borders Bukit Lawang. In addition, Sumatran orangutans can also be found in Aceh, West Batang Toru River, East Sarulla, and Sidiangkat.

The Sumatran orangutan is the rarest orangutan species, with a Critically Endangered (CR) status from the IUCN. Habitat loss, illegal hunting, and illegal trade are threatening the orangutan population.



Characteristics of Sumatran Orangutans

Sumatran orangutans have long, shaggy reddish-brown hair, a feature that distinguishes them from Bornean orangutans. Males are much larger than females, with faces adorned with flanges or cheek pads that develop as they mature. Adult males can weigh up to 90 kg (198 lbs), while females are smaller, weighing around 45 kg (99 lbs).

Behavior and Ecology


Behavior and Ecology of Sumatran Orangutan

Primarily arboreal (tree-dwelling) and spend most of their time in the canopy, they are solitary animals, with adult males being largely solitary while females and their offspring form small social groups. You can also see them enjoying fruits, leaves, and sometimes (although very rarely) eating insects, small animals, or bird eggs. As wild animals, they are built to hunt their own food to survive the wild, so remember upon sighting an orangutan to never feed them as this can change their behaviour.

Conservation Efforts


Conservation Efforts For Sumatran Orangutans

Conservation efforts are diverse involving habitat protection, anti-poaching measures, and rehabilitation programs for orphaned and displaced orangutans. Our organization, the Sumatran Orangutan Conservation Programme (SOCP), works to protect these orangutans and their habitats, promoting sustainable land use and reforestation initiatives. Our goal is to rescue, rehabilitate, and reintroduce orangutans back to the wild. To know more about what we do, visit our website.

By getting to know the Sumatran orangutans better, we can better understand the importance of protecting them and their habitats. Let’s support conservation efforts for a better future for our ecosystem and for the next generations!
