To gaze into the soulful eyes of an orangutan is to look into our very own future. Known to the Malays as the ‘man of the forest’, this tree-dwelling mammal shares almost 97% of its genetic sequence with humans and its predicament mirrors that of our own.

A highly intelligent creature, with long, powerful arms and grasping hands and feet, the orangutan moves through the treetops of lowland forests with ease. It lives a solitary existence, feasting on wild fruits like lychees, mangosteens and figs, and slurping water from holes in trees.

But the loss and degradation of its forest home, largely through unsustainable (and often illegal) timber harvesting, now has the orangutan – Asia's only great ape – out on a limb. And it’s not alone. Healthy forests are just as vital to the livelihoods and culture of the Indigenous people of Indonesia and Malaysia, not to mention a myriad other forest animals and plants.

Why it matters 

Orangutans are the ultimate forest gardeners, spreading seeds to help maintain the forest ecosystem. Not only is this important to a host of other animals, including the Sumatran tiger, Asian elephant and Sumatran rhino, it helps to ensure resources for people. By conserving the orangutan’s habitat, we’re also protecting other species and benefiting local communities.

Its extremely slow reproductive rate makes the orangutan highly vulnerable. Females take a long time to reach sexual maturity (10-15 years), usually give birth to just one infant every 6-8 years, and the youngster stays with its mother for about the first 10 years of its life. This means that the interval between babies can be as long as 10 years and orangutan populations can take a long time to recover from declines.

With human pressures increasing, orangutans face a growing risk of extinction.

Species Bio

Common Name

Bornean orangutan

Scientific Name

Pongo pygmaeus


Population: Borneo’s orangutan population is estimated to have been 288,500 individuals in 1973, but current estimates are 55,000 individuals.


Listed as Critically Endangered under the IUCN Red List


Orangutans can live up to 50 years in the wild. Females first reproduce between 10-15 years of age. They give birth, at the most, once every six years, and the interval between babies can be as long as 10 years.


Did you know?

Orangutans usually give birth to a single baby or occasionally twins. orangutans stay with their mothers for the first 7-11 years of their life.


The challenges they face

Orangutans – in both Sumatra and Borneo – are losing their treetop homes and food as forests are converted to oil palm and timber plantations (largely to feed the pulp and paper sector). It's a major threat to their survival.

In both cases, fire is often used to clear the land, and it can rapidly spread out of control – especially across dried peat swamps – adding to the already devastating impacts of deforestation.

Ongoing deforestation and habitat loss brings orangutans into closer and more frequent contact with humans, especially when forests no longer contain the food they need. Sadly, humans often become a direct threat. They poach these gentle apes for the pet trade, for food, or in retaliation when they move into agricultural areas and destroy crops. Unfortunately, the large and slow orangutans are easy targets.

What you can do to help

No matter where you live, no matter how small your actions are, we can all play a part in helping to save the orangutan and its forest home.

Adopt an orangutan: Symbolically adopt one of these great apes through WWF and your donation will support WWF’s conservation efforts, including the protection of orangutans.

Shop wisely: Avoid buying endangered wildlife products when on holiday. The illegal wildlife trade is having a devastating effect on our endangered species.

Buy forest-friendly products: Choose recycled paper and FSC-certified wood products.

You can also support companies using palm oil certified to RSPO standards and buy products carrying the RSPO label.
