Borneo Orangutan Survival Australia Inc


The Borneo Orangutan Survival Foundation (BOS) was founded by Dr Willie Smits who in 1991 rescued a baby orangutan, left to die on a rubbish pile in a local market in Kalimantan. She was soon followed by others requiring rehabilitation, leading Dr Smits to incorporate the Balikpapan Orangutan Society in 1994 which later changed its name to BOS.

About Borneo Orangutan Survival (BOS)


Today BOS employs some 350 dedicated permanent experts and staff who care for nearly 900 orangutans in its rehabilitation centres in Kalimantan.

Orangutans have lost approximately 80% of their habitat in the past 20 years through illegal logging and the expansion of palm oil plantations. The population is estimated to be declining by up to 3,000 per year with some experts predicting extinction in the wild within 10‐15 years.

The BOS vision is the conservation of the Bornean orangutan and its habitat in co‐operation with the community.

It aims to achieve this through research and education, empowerment of local communities to develop sustainable solutions, working together with multi‐stakeholders as well as strengthening its ongoing activities in orangutan rescue, rehabilitation and release.

 BOS operates three major projects


The Nyaru Menteng rehabilitation and reintroduction centre in Central Kalimantan, founded and managed by Lone Dröscher Nielsen, is the world's largest primate rescue operation. The facility currently cares for over 600 orangutans while they go through the process of rehabilitation, learning forest skills such as nest building, finding food, and recognising predators.

The Samboja Lestari Project incorporates over 1800 hectares in East Kalimantan which is being reforested to form a permanent sanctuary for orangutans and other wildlife including over 50 resident sun bears. The project is an example of agriculture, reforestation and protection combining effectively. Tourists and volunteers staying at the Samboja Ecolodge are able to participate in the reforestation project with donors financing the project through the symbolic purchase of land.

The Mawas program is aimed at protecting some 240,000 hectares of reserve including peat domes, rich in biomass and an important store of carbon dioxide. There are about 3,000 wild orangutans living in this area. The program is managed by BOS working together with the provincial government of Central Kalimantan.

BOS is supported by sister organisations throughout the world, including Borneo Orangutan Survival (BOS) Australia Inc, which was incorporated in 2001.
