About Us

The Orangutan Foundation is a UK registered charity working to conserve the threatened orangutan and its globally important habitat, the tropical forests of Borneo and Sumatra.

Since its foundation in 1990, the Orangutan Foundation has developed a diverse range of programmes. Key stakeholders who include local communities, grassroot NGO’s, local business and regional government are at the heart of the Foundation’s work. With their inclusion comes conservation success and sustainability.

Being the first organisation in the UK to raise awareness about the plight of the species, the Orangutan Foundation continues to actively engage the public, worldwide media, corporate and governmental organisations. It is on the Executive Committee of the UNEP/UNESCO Great Ape Survival Project, a member of the Ape Alliance (www.4apes.com) and plays an active part in international networks to promote the conservation of orangutans through the protection of their tropical forest habitat.



Sir David Attenborough -

“Many congratulations on reaching your 20th year. I have seen first-hand what wonderful work the Foundation is doing, and I am sure that the situation today is better than it would have been without it. But there is still a great deal to be done. May your past successes encourage you and give you the strength to tackle what lies ahead.”

Illegal logging eradicated from Tanjung Puting National Park. Since 2003 the Orangutan Foundation has been actively protecting the National Park and its wild orangutan population (over 4,000 orangutans) with guard posts and forest patrols.

Strengthening borders. In the Lamandau Wildlife Reserve, Central Kalimantan, a 8,000 hectare oil-palm plantation was stopped and the Reserve’s area increased in size.

The Reserve is one of the few sites in Indonesia where orangutan can be released back into the wild. The Orangutan Foundation provides excellent veterinary care and monitoring for released orangutans. Discover more about the Orangutan Foundation’s conservation strategy for this Reserve and its precious wildlife.

Conserving the largest population of orangutans outside of protected areas. The Orangutan Foundation is the first international organization to work in the biologically rich and unique forests of the Belantikan Hulu region. In 2013, with partners it undertook surveys of the orangutan and gibbon populations. Read more about the Belantikan Conservation Programme –an essential conservation initiative.

Joanna Lumley - ”The work of the Orangutan Foundation punches far above its weight. Its long-sighted analysis of the horrors awaiting the rainforests and these great apes cannot be ignored. They deserve our strong support at every level. Having had the pleasure and honour of being with them at very close quarters in Indonesia, I have felt undeniable kinship with them, these huge people of the jungle. To ignore their needs in favour of commerce seems contemptible at best and unforgivable at worst. It isn’t yet too late to turn the tide, but the buzzing of the chainsaws draws closer every day.”
