Our Vision
Our vision is a world where orangutans are free from the threat of extinction and can live in the wild, unharmed by humans.
back to their home.
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.

On our 4th day of the 12 Days of Christmas, we celebrate our superhero, Kopral. It's his rescue anniversary today!
This video was filmed while he was on a sanctuary island with his little buddy, Marlon, and his female friend, Leslie.
Kopral, a double arm amputee and his unreleasable friends are part of our adoption family - and what more beautiful gift can you give to a loved one for Christmas than a symbolic adoption of Kopral?
Adopt Kopral & Friends here:
orangutans.com.au/meet-our-family/kopral_and_friends
(or link in bio)
Kept illegally as a pet for most of his young life, at four years of age, Kopral made a perilous and futile attempt to escape his captors.
After climbing an electricity pole, Kopral was severely electrocuted and left for dead for an entire week – it truly was a miracle that he survived.
When Kopral arrived at Samboja Lestari 16 years ago, he had severe burns covering most of his body, and sadly, both of his arms had to be amputated. Despite being a double amputee, he was an outstanding student at Forest School, climbing trees and building nests solely with his feet and mouth.
Because of his impressive skills and strong determination, he was selected to live a semi-wild life on one of our sanctuary islands. There, he thrived until fate intervened again: he seriously injured his right foot.
To treat his ankle, the veterinary team moved him to the socialisation complex at Samboja Lestari, where he is adapting well, climbing the enrichment structures, and making steady progress.
Your support helps us care for Kopral and his friends, as we sadly can never return them to the wild.

On Day 3 of our 12 Days of Christmas Orangutan Jungle Jingle, we are excited to showcase our Orangutan Jungle School's school buses—wheelbarrows skillfully driven through the complex by our amazing surrogate mothers.
Did you know that you can help us care for our little students this Christmas?
We urgently need a new facility at our relocated Nyaru Menteng Centre, which will serve as the operational heart of our rehabilitation efforts.
We are still far from our goal, but we must raise $50,000 by 25 December to be able to start building this essential facility.
