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.

Did you know that orangutans are incredibly versatile, feeding on more than 2,000 different plant species?
While they spend most of their foraging time feeding on fruit, they also eat leaf shoots, leaves, bark, flowers, fungi, pith, insects, honey, and the occasional egg.
One of their favourite jungle snacks is the tender shoots and pulp from the cores of rattan leaves and spines. Yummy!

this is a real good prank because somebody will go walking through the woods and see that thing running around out there and be like what in the world
You go, girl!
Amazing 🤩
With love and respect from Canada for all you do to help these beautiful Animals.
Omg this would be number 1 on my bucket list if I could afford it ❤️
Euer Engagement ist so hoch zu werten, ich weiß gar nicht, wie ich das ausdrücken soll. Ich zolle euch höchsten Respekt.
Por qué los transportan en jaulas? Por qué no de otra manera más amigable y menos estresante? Pregunto con humildad y desconocimiento. Pero son seres tan parecidos a nosotros , que sienten tan parecido y no trasladamos humanos en jaulas, por qué a ellos si?

Was seid ihr für tolle Menschen, die das den Tieren ermöglichen. Danke ❤❤❤❤❤❤❤❤❤❤❤❤❤

Discovery!
Researchers have found a previously unknown cluster of Tapanuli orangutans in a peat swamp forest in North Sumatra.
With fewer than 800 individuals remaining in the wild, the Tapanuli orangutan (Pongo tapanuliensis) is one of the rarest great apes in the world. Like the Bornean and Sumatran orangutans, this species is classified as critically endangered by the International Union for Conservation of Nature (IUCN).
The new findings reveal that Tapanuli orangutans also inhabit a peat swamp forest some 32 kilometres (20 miles) away from their known range in the Batang Toru forest.

Wonderful, so let's hope that they and their precious forest are protected 💜
Well the whole world knows now .....
Fantastic news!
That's right let all the poachers know exactly where to find them.
Fantastic 🌍❤️
Great news!
In a peat swamp presumably because it’s inaccessible to humans. Please keep it that way!
Now let them be.
Wow this is incredible news
Cannot wait to see pictures of them
Wonderful dont tell tourists protect them please
