The primeval rainforest surrounding Saran Mountain is situated a few of miles west of Tembak Lestari . This 75,000 acre rainforest holds hundreds of different species of plants and trees, thus making this forest the perfect environment for the orangutan.
The Saran forest gets protection from destruction by the nearby traditional Dayak communities. To them, this forest is a source of water, food and medicine and provides the Dayaks with their traditional needs. This is one of the reasons the traditional people are unanimously determined to protect and conserve this area. They are supported in their efforts by a variety of organisations, one of them being Orangutan Rescue.
