BOS Foundation now manages the largest primate conservation project in the world and is proving an inspiration for many other projects involved with conservation.

 BOS Foundation's activities are:

• Protection of the orangutans' and many other animal species' habitat

• Seizure, rehabilitation and the reintroduction of orangutans to the wild

• Public relations, environmental education, awareness raising, involvement of the local population and creating alternative livelihoods for local people

• Planting and cultivation activities, fire protection and monitoring of the rainforest as protection against illegal logging

More than 500 orangutans have been reintroduced to protected rainforest areas since BOS was founded in 1991 and over 150 animals are temporarily living on five wooded river-islands in Central Kalimantan. BOS Foundation's employees are currently fostering about 850 orangutans and 60 sun bears.
