Our Goals for 2030
“Saving Orangutans, Restoring Forests, and Protecting Borneo!”
At YOHK, we are committed to achieving the following by 2030:

What We Do

Protect and care for the forest as a shelter for orangutans
We will use every donation we receive to preserve orangutan habitat areas. We also freed up the area to be managed as a natural sanctuary for orangutans whose land ownership rests with the foundation.
Forest Protection &
Restoration
Our conservation efforts go beyond protecting orangutans. We safeguard thousands of hectares of forest, restore degraded land, and create safe havens for wildlife to thrive. Borneo’s rainforests are vital, and we’re dedicated to preserving them for future generations


Empowering Local Communities
We believe that conservation begins with people. By partnering with local communities, we promote sustainable livelihoods, encourage eco-friendly practices, and empower the next generation of environmental stewards.
