What an extraordinary creature the orangutan is. But, this ‘person of the forest’ (the literal meaning of orangutan in Malay) is now at serious risk.
A century ago, orangutans lived in forests all across south-east Asia – from southern China to the Indonesian island of Java. Today they’re only found on two islands: Sumatra and Borneo. The primary threat to orangutans is the extensive loss of their natural habitat due to logging, agricultural expansion (particularly palm oil plantations), and infrastructure development. Deforestation fragments their habitats, isolating populations and limiting their ability to find food and mates.
It’s vitally important to protect these incredible animals – Asia’s only great apes – and their rainforest habitat before it’s too late.
Why are they so important?
Orangutans are known as gardeners of the forest, because they help spread seeds around. You know how it works – they eat fruit from the trees, the seeds come out the other end, the forest spreads. Especially the larger seeds that don’t get spread by smaller animals.
Without that seed distribution, the rainforests of Borneo and Sumatra would be drastically different, and that would have impacts on all the people and animals that reply on those rainforests.
The people of Borneo and Sumatra depend on the orangutan’s rainforest for food, water, income and environmental protection.
Key facts about orangutans
Where do orangutans live?
Orangutans used to be found as far north as southern China, and as far south as the Indonesian island of Java. [1] Orangutans are now only found in the wild on the islands of Borneo and Sumatra. [2]
How many orangutans are left in the wild?
It's estimated that there is a total of around 119,500 orangutans remaining.
The total estimated population of Bornean orangutans is 104,700 individuals. [3] It's estimated that over 100,000 Bornean orangutans were lost between 1999 and 2015. [4]
There are around 13,846 Sumatran orangutans left in the wild. [5] Sumatran orangutans could decline by over 80% by 2060 compared to 1985 numbers. [6]
The Tapanuli orangutan has the smallest population with less than 800 individuals. [7]
How big is an orangutan?
Male orangutans are nearly a metre tall and weigh 60-85kg. This makes them the same weight as your average healthy human at the bottom end of the scale. Females are slightly shorter and half the weigh. Orangutans have an arm span of about 2.2 metres from fingertip to fingertip. [8]
What do orangutans eat?
Orangutans mainly eat fruit, but also eat young leaves, flowers, insects and tree bark. [2]
What is the IUCN status of orangutans?
There are about 104,700 Bornean orangutans in the wild and they are classed as critically endangered. [9]
There are fewer than 14,000 Sumatran orangutans left in the wild and they are classed as critically endangered. [10]
With less than 800 individuals the Tapanuli orangutan is critically endangered.[11]

How we're helping orangutans
Urgent action was needed to protect the estimated 300 – 400 orangutans that live in the Bukit Piton Forest Reserve. In 2007, in collaboration with the Sabah Forestry department and local partners, we set about restoring this important area.
Since then, some 345,000 seedlings have been planted to help the forest start to recover. The seedlings planted were a mix of fast-growing trees as well as fruit trees like figs to support the orangutans’ diet. But the mark of a true success of this decade long restoration effort is when wildlife begin to make use of replanted trees.

"I spent my childhood growing up in an oil palm estate in Sabah. The only thing that I saw outside in the morning and where I spent my time playing with my friends was the oil palm plantation. As I grow up I started to look at nature differently and excited to uncover what we have in our rainforest. I changed from a person who didn't know anything about nature to someone who enjoys nature and is now working to conserve one of our closest living relatives - the orangutan."
