Help our orangutans on their journey to freedom: 2021
After a very challenging 2020 we are ready to start our release program again to move our orangutans to either sanctuary islands, pre-release Islands, or out to protected forests. We have many releases planned for 2021, and need your help to meet our big release goals.
Check back regularly for updates.
