Our Vision

our two sanctuaries.
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.

magnificent creatures!!!
That was just so beautiful ❣️ I’m so happy they get to live wild again, they are sentient beings and it’s sad they have been jailed for so long through no fault of their own! Be free beautiful souls and no one touch them, let them be free and thrive❣️💕🙏🙏🇦🇺
🥰😍🥰😍
So beautiful! Enjoy your new lives, sweet ones.
