Five Orangutans Adapt Well in Kehje Sewen Forest

Our Post-Release Monitoring (PRM) team from Nles Mamse Camp has spent the past few weeks monitoring the five orangutans reintroduced in to the Kehje Sewen Forest on October 19. Collecting data on their progress and adaptation has proven quite challenging for the PRM team, as each individual orangutan has a different and unique approach to adjusting to their new environment.


Kent chose to explore the forest on his own following his release, and moved deeper into the forest to forage. He didn’t seem to mind the team observing him; he just went about his own business and continued foraging. This is the second release for Kent – he was first released in 2014, on the north side of the Kehje Sewen Forest, but was moved back to Samboja Lestari for medical treatment of a persistent wound. After two additional years care in Samboja Lestari, Kent this time moved quickly through the forest once released, shaking off the PRM team on the second day post-release. The last time the PRM team caught up with Kent, he was located two kilometres from his release point, in the heart of the forest.


Saprol is very good at hiding, which is a great skill, but makes observing him a challenge for our PRM team. On the second morning post-release, the team came across Saprol’s empty nest – it appeared he had risen early and had already moved on and out of sight. Our PRM team are still trying to locate Saprol, but it is likely he wandered deeper into the forest to explore, just like Kent. Saprol was last seen about one kilometre from his release point.

Jamur and J-Lo

This mother-daughter pair has a very close bond: The two like to forage together and share food, and both have a very good appetite! However, J-Lo is showing signs of becoming more independent, and now relies less on her mother’s help.


Several days after their release, Jamur and J-Lo met up with Leonie. Like meeting a long-lost friend, J-Lo happily spent time exploring and foraging with Leonie, but made sure she stayed close to Jamur.

As for Jamur, it seems she has found herself a new beau! A wild male, who initially joined the group together with Leonie, took an interest in Jamur. The two started spending time together and eventually copulated, then shared the same night nest.

Jamur and wild male orangutan


Rafli, the first flanged male to be released to the south of the Kehje Sewen Forest, has been making many long calls to announce his presence in the forest and attract females. His efforts have paid off; on day two of his release, Rafli managed to attract a wild female who approached him with an offspring. The mother-child pair, however, mingled only a short time before continuing on their way.

Rafli is a big eater, and has been feasting on fruits and leaves in the Kehje Sewen Forest. Rafli is also good at building nests; the monitoring team even saw him fashion a ‘pillow’ for his night nest! Rafli was last seen moving into the heart of the forest, away from his release point.

We’ll keep you updated on the progress of these orangutans as we move into 2017!

[PRESS RELEASE] BOSF Reflects on 25 Years of Work: “Orangutans Endangered yet Poorly Protected”

The Borneo Orangutan Survival (BOS) Foundation will hold a celebration called“Reflection, the BOS Foundation’s 25 Years of Caring for Orangutans” to mark its 25th anniversary. The event will coincide with Orangutan Caring Week, which is observed globally in the second week of November each year.

Jakarta, November 18, 2016. Since its inception in 1991, the BOS Foundation has rescued more than 2,000 orangutans and still cares for 700 more in its two rehabilitation centres; Nyaru Menteng in Central Kalimantan, and Samboja Lestari in East Kalimantan.

The Bornean orangutan is classified as “critically endangered” by the International Union for Conservation of Nature (IUCN), and the Republic of Indonesia Law no. 5/1990 forbids the capture and captivity, and trade in protected species, which includes orangutans. Yet, the sheer number of orangutans that end up in rehabilitation centres indicates we still have a lot of work ahead of us to safeguard orangutans and their habitats, a cause the BOS Foundation remains committed to.

BOS Foundation CEO, Dr. Jamartin Sihite, said, “The responsibility of orangutan and habitat conservation lays on the shoulders of all stakeholders – the government, the community, the private sector, and mass organizations. Our 25 years of experience in this field has taught us that in order to succeed, we must work together. Not only that, we also need commitment, perseverance, and patience.

“We have established cooperation with many parties, and in this our 25th anniversary, the BOS Foundation would like to pause and reflect on both our achievements and our failures, in order to help us plan ahead,” Jamartin added. “Our long journey and the results achieved thus far would not have been realised without the involvement of parties that have supported the BOS Foundation and the orangutan and habitat conservation effort. To these parties, we would like to express our sincere gratitude. However, we acknowledge there are still many things we need to do to ensure that orangutans and their habitats are preserved.”

This celebration night is one in a series of events held by the BOS Foundation to celebrate its 25th anniversary year, with all parties invited that have been – and that are still – involved in cooperative work and partnership with the BOS Foundation. This event is only possible with the kind support offered by Palma Serasih Group, Swiss-Belhotel International, and PT Coca-Cola Amatil Indonesia. Several national figures, including Madame Megawati Soekarnoputri, the Head of the People’s Consultative Assembly of the Republic of Indonesia, Mr. Zulkifli Hasan; and the General Secretary of the Ministry of Environment and Forestry, and representatives for neighbouring countries that have supported our conservation effort, will attend the event. Their presence will be highly appreciated by the BOS Foundation as an indication of their on-going support for the national conservation effort.

The BOS Foundation would like to thank several artists and public figures who have given their time and support to the orangutan conservation effort in Kalimantan, including Bayu Oktara, Uli Herdinansyah, Hilbram Dunar, Muhammad Farhan, Jose Poernomo, Fade2Black, Nadine Alexandra Dewi Ames, Umay, Blink, Harsya Soebandrio, and Swara Maharddhika and Orangutan Lifesaver (OLS) communities. Their continued support helps the BOS Foundation in the on-going struggle to ensure the survival of Asia’s only great ape species.

#OrangutanCaringWeek: Help Us Care for Meryl and Her Friends!

In early January 2015, our Nyaru Menteng team together with BKSDA travelled to Tumbang Jiga village – located in the remote regions of Katingan Regency in Central Kalimantan – after receiving a report that a baby orangutan was being held captive.

In the village we were shown a tiny infant being kept in a small local rattan basket, normally used to carry produce from the farm. Our vet, Meryl, quickly lifted her out of the basket and could immediately tell she was suffering from a high fever. The confiscation was quickly concluded and the team transported the tiny female to Nyaru Menteng for medical treatment. We named her Meryl.

Vet Meryl holds baby Meryl, her namesake

At Nyaru Menteng the vet team discovered that Meryl was suffering from influenza and malaria. But with 24-hour care, provided by our dedicated medical team and babysitters, she made a full recovery and started her rehabilitation in the Nursery Group where she spent the next year developing her skills, and learning and playing with other baby orangutans.

Meryl with her friends

In February 2016, Meryl skills had developed enough to move into the larger nursery group, for the stronger and more daring young orangutans. Meryl is one such individual, and while she is still a toddler, she has no trouble climbing high up in the trees.

We are delighted with Meryl’s progress and will continue to nurture her as she develops new skills in the hope that one day she can once again live freely in natural habitat.

Why we need your help!

The recent forest fires and haze have left many young orangutans orphaned and we have already rescued 6 infants in the last few weeks bringing our baby group to 22 orangutans. Even more are expected to arrive and our current Baby House is too small and insufficient for our needs. We need to build a bigger Baby House to accommodate all of our babies and provide them with the round the clock care they need in a hygienic, suitable environment.

What we want to do (Click here)

Our new Baby House will be a brand new facility, large enough to house all our babies and any new arrivals. We have designed outdoor forest schools and indoor play areas so that even when it is raining, our babies can continue to learn and play. We have designed two separate buildings; one for healthy babies which have completed health screening and one for incoming babies who need to be quarantined before they can join the rest of the babies. Each building is self contained with new kitchen and bathroom facilities, bedrooms for when we need one on one care with new or sick babies, and attaching outdoor sleeping enclosures for older orangutans. We are not just building a house, we are building a home in an environment where our babies have the best opportunities to learn and receive the dedicated love and care they need to be healthy, happy and confident young orangutans.

Fathia is a female baby orangutan rescued by BOSF-Nyaru Menteng together with BKSDA Central Kalimantan from a local person on Linau Village, Tumbang Jutuh, Gunung Mas Regency, Central Kalimantan on September 1st, 2015, when she was 10 month old.


On 21st September 2015, a rescue team from Nyaru Menteng in collaboration with BKSDA Central Kalimantan rescued a 4-month old male orangutan, weighing only 1.5 kgs, from a local settler in the Hiang Bana transmigration area, Katingan Regency.

Meet some of our resident Babies


Meryl was found in a very poor condition in Tumbang Jiga Village, Katingan Regency on January 7th, 2015. She was weak and thin. The owner put her in a lanjung, a Dayak traditional bag made of plaited rattan, usually used for carrying crops or firewood. She could barely move inside the bag.


Four month old Sura did not only suffer the tragic loss of his mother at a very young age, he also suffered the loss of three fingers on his left hand during his capture.


Madara was separated from his mother, kept as pet and almost sold on the illegal pet trade. Fortunately a good man stepped in and saved him from this terrible fate and handed him over to the BOS Foundation team in Nyaru Menteng.


Yutris, is a 7-month old baby male orangutan weighing 3 kgs. He was apparently found without his mother by bird hunters and taken care of by a local resident of Madara before being taken to Buntok, South Barito regency and then finally on to Nyaru Menteng on May 6th, 2015.

Pre-Release Salat Nusa Islands Finally in Use

BOS Foundation Nyaru Menteng’s goal of utilising the Salat Nusa islands as a new pre-release area for rehabilitated orangutans has finally been achieved, with last week’s release of 12 Forest School graduates for the first time to Badak Kecil Island, in Pulang Pisau Regency, Central Kalimantan.

The BOS Foundation secured the acquisition of 655 hectares of forest on Badak Besar and Badak Kecil islands in 2015; however, the operational stage was halted due to technical reasons. We finally received the support we needed after establishing a partnership between various stakeholders, including the regency government, the local community, and PT Sawit Sumbermas Sarana Tbk. (PT SSMS), a company committed to environmental conservation. Once the partnership was formed, things moved quickly due to the mounting pressure of finding more pre-release areas for the BOS Foundation’s rehabilitated orangutans waiting in Nyaru Menteng.

The BOS Foundation’s Orangutan Reintroduction Program in Nyaru Menteng currently has up to 470 orangutans undergoing rehabilitation, with 91 individuals currently inhabiting three pre-release islands already in use: Palas, Kaja, and Bangamat islands, with a combined total area of 221 hectares. Meanwhile, nearly another 100 orangutans are being housed in Nyaru Menteng enclosures, as they have already completed Forest School and are awaiting their release.

The availability of Salat Island, which our survey indicated as a suitable place for pre-release purposes, is indeed a major breakthrough (Read more about Salat Island here: A Little Piece of Orangutan Heaven). Furthermore, the partnership with PT SSMS has expanded the available area to 1,434 hectares.

The recent release of these 12 orangutans was conducted in two batches, with the first batch released on November 3, 2016. The cages were opened by several VIPs – the Governor of Central Kalimantan Province, H. Sugianto Sabran; a representative for the Pulang Pisau Regent; the local village chief; Head of the Central Kalimantan BKSDA, Dr. Nandang Prihadi MSc.; the President-Director of PT SSMS, Vallauthan Subraminam; and BOS Foundation CEO Dr. Ir. Jamartin Sihite. The attendance and participation of these guests demonstrates the active and ongoing cooperation between all stakeholders concerned with orangutan and habitat conservation in Central Kalimantan.

The first batch saw the release of seven (7) orangutans, consisting of five (5) females and two (2) males. BOSF Nyaru Menteng assigned a group of technicians and a veterinarian to the island to observe the released individuals’ progress and adaptations. The second batch, consisting of five (5) more rehabilitated orangutans, was transported and released at the same spot the next day, on November 4. Our observation team have, to date, reported nothing but positive progress for all 12 released orangutans.

Our Post-Release Monitoring (PRM) team in Salat Island

BOSF Nyaru Menteng plans to transfer the remaining rehabilitated orangutans – that are ready to go to pre-release islands – by the coming year. We are confident that with sound cooperation from all stakeholders, especially with the government and the people of Pulang Pisau Regency, a positive outcome shall be achieved. We will continue to strive to protect orangutans and their habitats!

Lesan and Her Baby Seen with Casey

Early morning during a recent daily patrol, our Kehje Sewen Post-Release Monitoring (PRM) team spotted the familiar signs of an orangutan approaching. Off in the distance, tall trees were leaning at great angles and then springing back into an upright position as an orangutan moved from tree to tree. The PRM coordinator and a volunteer set off to identify the individual, who had stopped on a branch high up in the trees.

The team expected to meet Casey, a female orangutan who had been spotted in the area the day before, but on approach saw that the orangutan was carrying a baby. It was Lesan and her 5-month-old infant! The team was ecstatic to meet the pair again, as they had not been seen since July, after Lesan returned deep into the forest to raise her newborn during its most crucial first months.

Lesan and her baby

Not long after arriving at the forest’s edge, where Lesan was resting, the team heard more rustling further up the hill. It was Casey – she and Lesan appeared to be travelling together. The two females had most likely built their night nests in close proximity, and met each other in the forest whilst foraging for food. Casey and Lesan were last seen travelling together months ago, when Lesan patiently allowed Casey to observe her with her new baby, who at the time was just a few days old (Read more here: Lesan Becomes a Mother).

Lesan, her baby, and Casey together in a tree

On this occasion, Lesan led the way through the forest while Casey followed closely behind. They sat together on the bough of a tree while Lesan groomed and nursed her baby, with Casey paying close attention. Eventually, they parted ways, after Lesan headed toward a tree that has become a popular feeding destination among orangutans in the Kehje Sewen Forest. She climbed to the very top, with her baby keeping a firm grip on her back: With eyes wide open to the world around her, Lesan’s baby is now strong enough to support herself as her mother travels through the forest. Lesan spent an hour stripping and feeding on bark with her strong jaws and teeth before moving off again.

The PRM team followed, collecting valuable behavioural data on the mother-infant pair along the way. It is always a challenge following Lesan, as she is an incredibly skilled climber, and is both fast and quiet, which bodes her well in the wild. Eventually, Lesan slipped out of sight, and the team returned to camp feeling happy to have witnessed mother and baby doing so well in their first few months together in the forest. We look forward to meeting them again, and providing more updates on their progress!

[PRESS RELEASE] BOS Foundation Establishes an Orangutan Conservation Area on Salat Island

Following a long process to secure the rights to utilize parts of Salat Island in Pulang Pisau Regency, Central Kalimantan, the Borneo Orangutan Survival (BOS) Foundation in collaboration with the local community have been granted permission to establish an orangutan conservation area on Salat Island, whilst also protecting the environmental services rendered by this essential ecosystem. To commence this important initiative the BOS Foundation is releasing 12 rehabilitated orangutans on to Salat Island where they can complete their final pre-release learning.

Nyaru Menteng, Central Kalimantan, 3 November 2016. The BOS Foundation in Nyaru Menteng (Nyaru Menteng) is currently rehabilitating around 500 orphaned or displaced orangutans through confiscations and rescues working together with the Central Kalimantan Natural Resources Conservation Agency (BKSDA). These orangutans are undergoing a lengthy process of rehabilitation before they can be released back to their natural habitat. The rehabilitation process can take seven years. It starts in Baby School and works up through different levels, much like a human school system, until the orangutans are ready for final reintroduction to natural habitat. The last part of this rehabilitation process needs to take place on natural islands where the orangutans have the opportunity to live in an environment similar to their natural habitat in the forest, but where their adaptation can be adequately monitored to ensure they are ready for reintroduction.

The ideal current carrying capacity in Nyaru Menteng is 300 orangutans, whilst we are caring for almost 500. A large majority of these orangutans are ready to embark on the final pre-release stage, however the three existing pre-release islands located in the Rungan River managed by Nyaru Menteng, have reached full carrying capacity. The BOS Foundation therefore needs a new area of land specifically to cater for the final pre-release stage orangutans. There are around 60 orangutans who have finished rehabilitation within BOS Foundation Forest Schools and ready for the next stage, with more than a hundred queuing behind them.

In total, Salat Island, which is located in Pulang Pisau Regency of Central Kalimantan, covers 3,419 hectares and of this the BOS Foundation has acquired 655 hecards. Salat Nusa island has suitable intact natural forest, is islolated from the mainland all year-round, has no wild orangutan population, supports sufficient orangutan foods and adequate carrying capacity to support large numbers of orangutans as they adapt to life back in the forest.

The agreement between BOS Foundation and the government of Central Kalimantan Province related to orangutan and habitat conservation in Central Kalimantan states that the BOS Foundation working area comprises the entire Central Kalimantan Province. As agreed upon between BOS Foundation, Central Kalimantan BKSDA and the government of Pulang Pisau Regency, the parties will work together to reintroduce as many rehabilitated orangutans as feasible. In order to prepare them, a pre-release forest area that can support the final important process of their rehabilitation is needed. Badak Kecil and Badak Besar islands of Salat Island can support this and will significantly help accelerate the whole process of orangutan reintroduction. Carrying capacity of these two islands are estimated at 100-200 orangutans. These areas also have the potential to become a long-term sanctuary for orangutans, which are unreleasable due to injury, but who also deserve to live freely in an area which can be easily monitored. Through partnership with PT Sawit Sumbermas Sarana (SSMS), a palm oil producing company group, this area has been extended to more than 2,000 hectares in total.

The BOS Foundation is willing to establish a cooperation with companies that demonstrate strong commitments and responsibilities towards orangutan conservation and the environmentn and PT SSMS has proven their determination towards achieving this goal.

BOS Foundation CEO, Dr. Ir. Jamartin Sihite said, “We still have obligations to fullfil the Indonesian Orangutan Conservation Stratetgy and Action Plan which states that by 2015, there should be no orangutans within rehabilitation centers. We are still facing difficulties with the huge number of orangutans in our rehabilitation centers, both those individuals who are ready for reintroducion, and both need forest areas similar to natural habitat. Cages, however comfortable and well-facilitated, are no place for them to live. BOS Foundation therefore strives to place orangutans cared for within our rehabilitation programs into suitable areas, especially in natural habitat with sufficient food availability, no competition from wild orangutans, and safe from possible future exploitation. Salat is ideal according to our surveys, and the BOS Foundation calls to all environmental stakeholders, the government, private sector and organizations to place emphasis on commitment and support of orangutan and habitat conservation for collective benefits.”

Vallauthan Subraminam, President Director of PT Sawit Sumbermas Sarana Tbk., said, “We are a company who put the highest regards and committed to plantation management based on principles on sustainable management which is also described as one of the company’s principles, case for the environment. We realize the importance of habitat and ecosystem conservation efforts. We therefore strongly support the BOS Foundation to prepare an area with conditions similar to the orangutans’ natural habitat as a sanctuary for orangutans ready for reintroduction to the forest, and for those unreasable orangutans. By providing an additional area of 1,434 hectare of Salat Island to add to the area already acqurired by BOS Foundation in the same region, we are more than ready to provide our solid cooperation in this initiative and and work together with other stakeholders. We want to show that a sustainable business can work hand in hand with conservation efforts for the benefit of all. In the future, we even plan to develop this area into a tourist destination, and provide a better livelihood for the community.”

Salat island is considered suitable as an Essential Ecosystem Area; it comprises a wetland ecosystem, in this case, the river which serves important environmental functions to both local biodiversity and human lives, including watershed protection, reducing the risk of floods, etc.,

H. Sugianto Sabran, Governor of Central Kalimantan fully supports the initiative and said, “the Government of Central Kalimantan greatly welcomes the effort and actions taken by the BOS Foundation to establish cooperations with other stakeholders, in this case, from the private sector, in conserving orangutans and their habitat. As governor, I fully pledge my support on this monumental cooperation. Environmental conservation is a collective effort and this is particularly a special moment for us to follow up. The degree of forest destruction we experienced last year through fire was significant, we now face a great task ahead; that is to rehabilite, conserve, and protect the remaining forest areas along with its biodiversity within.”

H. Eddy Pratowo, S.E., M.M., Pulang Pisau Regent asserted, “the Pulang Pisau Regent is in full support of orangutan conservation as this protected rare species has been an eternal part of our lives in Central Kalimantan. We appreciate the effort taken by BOS Foundation and PT SSMS to conserve this essential area and involve participation of the people of Pulang Pisau in the process of orangutan and habitat conservation. I and the entire staff of Regency Office offer our full Avallauyhan Sunrminum, Predient dierisupport towards this utilization of Salat island.”

The establishment of this orangutan conservation area is testament to positive co-operation between the BOS Foundation and other stakeholders, namely the government of Central Kalimantan Province, government of Pulang Pisau Regency, Central Kalimantan BKSDA, and the people of Jabiren Raya Sub-District who are concerned with Indonesian orangutan conservation. The BOS Foundation also expresses gratitude for the support by PT Sawit Sumbermas Sarana and our global partners including John Cochrane from Australia, BOS Australia, BOS Germany, BOS Switzerland and World Animal Protection (WAP) who have generously funded this extremely important initiative.

BOS Foundation’s 9th Orangutan Release in Kehje Sewen Forest

We are working tirelessly throughout our 25th anniversary year, and together with the East Kalimantan BKSDA we released five more orangutans to the Kehje Sewen Forest on October 18.

One of the five, a male named Kent, was this time re-released to the Kehje Sewen Forest after first being released on March 22, 2014, and brought back to Samboja Lestari two months later after he was found with serious injuries following an altercation with another male. After two additional years of rehabilitation to recover and regain his survival skills, Kent joined Rafli, Jamur, J-Lo and Saprol in our 9th release to the Kehje Sewen Forest!

Like all BOS Foundation releases, appropriate safety measures were put in place to ensure a safe and successful outcome. After being sedated by our veterinarian team, the five orangutans were carefully transferred to individual transport cages and loaded onto cars, ready to travel to the Kehje Sewen Forest, in East Kutai and Kutai Kertanegara regencies.

Release Ceremony at Governor’s Office

Outside the front lobby of the East Kalimantan Governor’s office, an official ceremony was held to mark the release of the five orangutans. Several VIPs attended the ceremony, including BOS Foundation CEO Jamartin Sihite; the Governor of East Kalimantan Province, Prof. H. Awang Faroek Ishak; head of the East Kalimantan BKSDA, Sunandar Trigunajasa; Ministrial Special Envoy for Environmental and Forestry Media Communication, Nova Harivan; expert staff member for the Governor of Agriculture, Natural Resources and Environment, Professor Marlon Ivanhoe Aipassa; and head of the Sub-Directorate of Species Preservation from the Ministry of Environment and Forestry, Puja Utama.

The three male and two female orangutans took a 12-hour road trip from the Governor’s office to Muara Wahau, the capital of East Kutai Regency.

The team stopped every two hours to check on the orangutans

Obstacles Faced by the Release Team

The rain didn’t let up throughout the entire trip, which added to the complexities of transporting orangutans. On the last leg of the trip – through an ex-timber concession area – the track was muddy and extremely slippery, forcing the team to pull and push bogged cars free to reach the end of the road (the last place reachable by car after a gruelling 5-hour trip from Muara Wahau).

Our dedicated team worked tirelessly to ensure the rehabilitated orangutans got to the release points

At the end of the road, members of the Wehean Dayak tribe performed a traditional dance ritual and ceremony to bless the release.

Team members faced further challenges when they had to navigate on foot, a 200-metre, steep trail in wet and slippery conditions in order to reach the banks of the Telen River. They then had to cross the flooding river and push a truck from Nles Mamse Camp waiting across the river to carry the transport cages to the release points.

The final leg of the trip was completed by late afternoon, and we opened the cages to release the orangutans at around 5 p.m.

As it was getting dark and the rain was still falling, the PRM team decided to build a flying camp near the release points rather than risk walking back to Nles Mamse Camp. This allowed the team to start early nest-to-nest monitoring of the newly-released five.

With this 9th release from Samboja Lestari, the total number of orangutans released by the BOS Foundation to the Kehje Sewen Forest since 2012 now stands at 49 individuals and in Central Kalimantan we have released 185. In celebration of our 25th anniversary, we plan to release a total 250 orangutans back to Kalimantan’s forests by the end of this year.

Thank you to all parties who generously supported this release, and who continue to promote and aid the orangutan conservation effort!
