The Central Kalimantan Orangutan Reintroduction Program at Nyaru Menteng was established in 1999, specifically to provide care and rehabilitation to displaced or orphaned orangutans rescued from areas of habitat loss through human development activities.
Located in Nyaru Menteng Arboretum, about 30 kilometers from downtown Palangka Raya, our main activities at Nyaru Menteng include orangutan rescue and translocation, the provision of welfare and healthcare, rehabilitation, and reintroduction. Conservation of habitat and wildlife can only be achieved by working together with local communities and other stakeholders, hence in all areas of our work we fully engage with local communities and schools on community development activities and outreach conservation education.
The BOS Foundation has rescued over 1000 orangutans in Central Kalimantan and currently care for and support over 600 orangutans at Nyaru Menteng
Orangutan Rescue and Release
Orangutans that have been displaced from areas of natural habitat due to human development activities causing widespread habitat loss, are often forced to range long distances in search of food. Often they wander into oil palm plantations or community gardens as they simply have no other alternative. Together with the Central Kalimantan Conservation and Natural Resources Authority (BKSDA), we rescue orangutans from these situations and if healthy, can immediately release them to areas of safe, secure natural habitat. This practice is commonly known as translocation. In situations where an orangutan has suffered injury or illness, we provide dedicated healthcare to ensure their recovery for future translocation or later reintroduction.
Orangutan Rehabilitation and Reintroduction
The BOS Foundation manages two reintroduction programs; Nyaru Menteng in Central Kalimantan and Samboja Lestari in East Kalimantan. Both of these programs focus on rehabilitation and reintroduction activities in line with national and international (IUCN) guidelines and criteria. When an infant orangutan is taken away from its mother, he or she loses a whole life time of early learning. Therefore, the purpose of rehabilitation is to equip orphaned orangutans with the skills they need to survive once they are old enough to be reintroduced to the forest.
THE PROCESS OF REHABILITATION
Healthcare and Quarantine
Each orangutan arriving at one of our reintroduction programs goes through routine quarantine procedures and health checks (physcial and psychological). This is very important as many rescued orangutans have been exposed to human diseases which they would not normally encounter in the wild.
The majority of the orangutans who enter our facilities are still very young, so in need of orangutan-peer interaction and daily lessons on forest survival. During rehabilitation, orangutans are taught and encouraged to build nests, select appropriate natural foods and recognise natural predators. This process starts in ‘Baby School’ and progresses through different levels of ‘Forest School’, where each day is spent in the forest learning new skills. Skills aquired by each individual are assessed before moving them up through the levels. Orangutans then progress to one of pre-release islands, which is a halfway forest for the final stage of rehabilitation. Dependent on the age and existing skills each orangutan has, rehabilitation can take up to 7 years.
Our overriding goal is to reintroduce orangutans back to secure natural habitat to establish new viable long-term populations to bolster conservation of the species in the wild. The forest areas we have secured for our reintroduction program in Central Kalimantan are established with camps, equipment and trained personnel to ensure that our Orangutan Field Monitoring Programs are able to continuously monitor each orangutan’s adaptation to their natural habitat. This involves a great deal of ongoing logistical support, planning and is very costly. You can support our Release Programs through your donations.

Very sadly some of our orangutans can never be returned to the wild due to illness or injury. Our dedicated team continues to provide welfare and healthcare to these individuals, which they will need for the rest of their lives. An orangutan can live for 50 years in captivity and we will ensure that we continue to provide them with the highest level of long-term care and sanctuary.
