Adopt an orphaned orangutan
Orangutans are on the brink of extinction. Help provide the care and rehabilitation
they need to return to the wild.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

Today, we celebrate World Wetlands Day. This year's theme, "Wetlands and Traditional Knowledge: Celebrating Cultural Heritage," holds special significance for us.
With numerous hectares of precious peat swamp forest under our care, we greatly value the traditional knowledge and support of the indigenous communities surrounding our work areas.
For us, environmental conservation begins with the local communities. By protecting Indonesia's unique ecosystems, including its vital wetlands, we also help preserve the livelihoods and traditions of the people who call this country home.

Do you remember little Momo, who was rescued by BOS in mid-2025?
She is currently continuing her rehabilitation journey at the Nursery Group, where young orangutans learn essential life skills in a safe and supportive environment.
Along with her peers, Momo is gradually developing her own personality.
Although she is still very young, Momo has already shown that she is not one to simply stay close and observe; instead, she stands out as a curious and energetic explorer.
Find out more about her amazing progress here:

If you would like to support orangutans like Momo on their long rehabilitation journey, please consider adopting one of our orphaned orangutans here:
