Tiny and Ajeng Get Cosy in Kehje Sewen

Unexpected Encounter

Our PRM team from Nles Mamse Camp in the Kehje Sewen Forest recently set out before dawn to conduct nest-to-nest monitoring on Tiny, a young male orangutan we released in December. The team picked up Tiny’s signal and was moving in its direction, when they met Ajeng, a female orangutan released two years prior to Tiny’s release. Since the team had planned to observe Tiny, they passed up the opportunity to collect data on Ajeng. Perhaps this intrigued Ajeng, as she followed the team to transect #28, where they caught up with Tiny. Ajeng quickly approached Tiny; to our knowledge, this was the first time they had met.


The two sat next to each other and happily shared food. Tiny appeared healthy and fit – it was clear he had adapted well to forest life. Tiny and Ajeng ate forest fruits, termites, and some shoots. After their meal, they copulated. We did not expect these two to get this close on their first encounter!

Tiny and Ajeng together

Too busy enjoying one another to care about what was going on around them, Tiny and Ajeng paid little mind to the PRM team’s presence as they took data and documented the pair. Until the sky began to turn dark and the team wound down observations for the day, it seemed that Tiny was content to follow Ajeng wherever she went.

Tiny’s Big Nest

The following day, the PRM team found the two still together, and with similar patterns of movement: whenever Ajeng moved, Tiny followed. That day, Ajeng and Tiny came across Heli and Hanung, and the four spent some time together. Tiny, the most recent newcomer to the Kehje Sewen Forest, interacted well with the other three, more senior orangutans.

As the sun began to set, it was time for the orangutans to prepare their nests for the night. Tiny slowly moved away and climbed higher, and we soon heard cracking sounds from above – Tiny was building a nest. Oddly, the nest he built was rather large, and when it was completed he quickly jumped in to rest. A short while later, it became apparent to us why he had constructed such a large nest: Ajeng came and joined him. Tiny had built a nest for two! This is such great progress for 11-year-old Tiny!

We are thrilled that Tiny and Ajeng have met each other, and seem to be enjoying each other’s company. We hope this new pair will produce another wild-born baby, and contribute to the creation of a new orangutan population in the Kehje Sewen Forest!

BOSF Kicks Off New Year with Orangutan Release

In collaboration with the Central Kalimantan BKSDA, we have started 2018 with the release of four orangutans in to the Bukit Baka Bukit Raya National Park, in Central Kalimantan! These four orangutans have each completed a long rehabilitation process and are now ready to start their new life in the wild.

Challenging Road to Freedom

On January 10, Pong, Rutan, Agis, and Jaka were sedated and examined by the medical team at Nyaru Menteng. Once asleep, our team carefully moved the four into separate transport cages, then loaded the cages onto the back of the utility vehicles that would take them directly to Tumbang Tundu, the last village accessible by car. During the trip, and in li      ne with our Standard Operating Proceedures, the team stopped every two hours to check the orangutans.

The rain was heavy and extra special care was needed on the wet and slippery roads. After four hours of driving, the team arrived at the ferry crossing in Tumbang Manggu village. Torrential rain had caused the river to rise, bringing bundles of potentially dangerous drift logs downstream. The team sensibly decided to stay overnight at Tumbang Manggu and continue the trip the next morning.

After crossing the river, the road across was flooded which slowed transportation down even more, and the team had to prepare for other obstacles they might face further down the road.

Unlike other release trips, the team reached Tumbang Tundu around noon time. They quickly transferred the transport cages to the small motorized ‘klotok’ boats. After a 5-hour trip upstream, the team had reached the location, and carried the transport cages from the river bank to predetermined release points.

Four Friends Embrace Freedom

On Thursday evening, the four orangutans were successfully released! Pong’s cage door was opened first, followed by the cages of the beautiful female orangutans, Rutan and Agis. The youngest orangutan, Jaka, was the last to gain freedom in the Bukit Baka Bukit Raya National Park.

Agis’s transport cage was opened by Mayzura Restalia

Jaka’s transport cage was opened by Oetomo Wiro

After the last cage was opened, the Post-Release Monitoring (PRM) team quickly began working in pairs to observe and gather data on the released orangutans. They will follow and take notes on the released orangutans for 30 days, through nest-to-nest observations – from dawn till dusk. These data provide valuable information on how orangutans adapt to life in a natural habitat.

This release brings the number of rehabilitated orangutans released to the Bukit Baka Bukit Raya National Park since 2016 to 75. Since 2012, the BOS Foundation has released 330 orangutans from the Nyaru Menteng and Samboja Lestari rehabilitation centers to sites located in East and Central Kalimantan.

We would like to thank all stakeholders for their support and contributions to ensuring the conservation of orangutans and their habitats in Indonesia.

[PRESS RELEASE] First Release for 2018 to Celebrate World One Million Tree Day

This release will be the 8th conducted in the Bukit Baka Bukit Raya National Park (BBBR-NP) by the BOS Foundation, in coordination with the Central Kalimantan BKSDA, the BBBR-NP office, and USAID Lestari. With this release, the total number of orangutans released to the area will reach 75.

Nyaru Menteng, Central Kalimantan, January 10, 2018: Continuing on with the #OrangutanFreedom campaign – with the target of releasing as many orangutans as possible to natural forests and to pre-release islands, since 2017 – as well as commemorating World One Million Tree Day, the BOS Foundation together with the Central Kalimantan BKSDA and the BBBR-NP office will today release four more orangutans from the BOSF Nyaru Menteng Rehabilitation Center to the BBBR-NP forest in Katingan District.

The four orangutans include two males and two females, who will be transported over land and river in a 10-12-hour journey from Nyaru Menteng to predetermined points in the BBBR-NP.

Dr. Ir. Jamartin Sihite, BOS Foundation CEO, said; “These four orangutans are ready to taste life in the wild, and delaying their release to wait for others to join them would not be a wise choice. We still have hundreds of orangutans waiting at our rehabilitation center in Nyaru Menteng. To accelerate the release process, we have prepared a number of pre-release islands to help orangutans become familiar with environments that resemble natural, wild forests. And to continue our #OrangutanFreedom campaign, this year we have set a target to release at least 200 orangutans to either pre-release islands, sanctuaries, or wild forests.

Please bear in mind that the rehabilitation process takes years to accomplish. Orangutans are not a species that we can simply release to the forest; it takes a long time for them to hone the vital skills they need to survive in the wild. Not only does it take time, but it is also costly. We can only succeed at conserving orangutans and their habitats if we work together. It is not something we can do alone. Protected by law, orangutans are the closest human relatives, and they play an important role in regenerating forests. We are compelled to work hard toward preserving this extraordinary species, as sustainable and protected forests are instrumental in sustaining a good quality of life for all. In the new year, let’s move forward with new hope.”

Ir. Adib Gunawan, Head of the Central Kalimantan BKSDA, said; “We need to push forward with all efforts to release orangutans back to their natural habitats, because there are still hundreds of orangutans waiting in the rehabilitation centers. In marking World One Million Tree Day, the Central Kalimantan BKSDA, in cooperation with the BOS Foundation, the BBBR-NP office, and USAID Lestari, will again release orangutans from Nyaru Menteng to the Bukit Baka Bukit Raya National Park in Katingan Regency. We fully welcome this cooperative effort.

As the orangutan conservation strategy and action plan stipulates – ‘ensuring the sustainability of the orangutan population and its habitats through partnership of the parties’ – we need to collectively continue to protect habitats and wildlife by involving all parties, including the community around the forest area.”

Ir. Heru Raharjo, M.P., Head of the Bukit Baka Bukit Raya National Park (BBBR-NP) Office, said; “We, as the bearers of responsibility and management of the Bukit Baka Bukit Raya National Park, greatly appreciate the cooperation that has been built between the BOS Foundation, the Central Kalimantan BKSDA, and USAID Lestari in conducting orangutan release activities in the BBBR-NP, which until now has seen 75 orangutans released to natural habitats. This many released orangutans living freely in the forest indicates a great achievement toward the conservation of this protected great-ape species. We, together with all stakeholders involved, will do our utmost to provide a good life for all released orangutans in the BBBR-NP, and hope they will create a new, wild population.”

This release activity, involving the BOS Foundation, the Central Kalimantan BKSDA, and the BBBR-NP office, also involves USAID LESTARI, which has committed to actively support the orangutan release program in the BBBR-NP until this year.To ensure a successful conservation effort involving all stakeholders, the BOS Foundation continues to work closely with the Government of Indonesia at all levels: the Ministry of Environment and Forestry; the Central Kalimantan Provincial Government; Katingan Regency Government; the Central Kalimantan BKSDA; and the Bukit Baka Bukit National Park office.The BOS Foundation would like to express appreciation for the support and contributions from a number of other partners, including the Katingan District community, individual donors, and partner organizations that assist with conservation efforts in Indonesia.

Editor’s Note:


Founded in 1991, the BOS Foundation is a non-profit Indonesian organization dedicated to the conservation of Bornean orangutans and their natural habitats, working together with local communities, the Ministry of Environment and Forestry of the Republic of Indonesia, and international partner organizations.

The BOS Foundation currently cares for around 600 orangutans in two rehabilitation centres, with the support of 440 highly dedicated staff members and experts in the fields of primatology, biodiversity, ecology, forest rehabilitation, agroforestry, community empowerment, communications, education, and orangutan welfare. For further information, please visit www.orangutan.or.id.


Since 2012, the BOS Foundation has released 330 orangutans to three release sites in Central (Bukit Batikap Conservation Forest and Bukit Baka Bukit Raya National Park) and East Kalimantan (Kehje Sewen Forest).

This is the 8th release conducted by the BOS Foundation in the BBBR-NP since August 2016. This release takes the total population of released orangutans in the BBBR-NP to 75 individuals.


USAID LESTARI is a collaborative project between the governments of the United States of America and the Republic of Indonesia. USAID LESTARI fully supports the efforts made by the Indonesian government to reduce greenhouse emissions and increase efforts to conserve forest biodiversity and mangrove ecosystems rich in carbon storage.

USAID LESTARI focuses on regions with unscathed primary forests, high carbon deposits and rich biodiversity. These regions include Aceh (the Leuser landscape), Central Kalimantan (the Katingan-Kahayan landscape), and Papua (the Lorentz Lowlands, Mappi-Bouven Digoel, Sarmi and Cyclops landscapes).



Pong was confiscated from a villager in Tumbang Samba, Katingan Regency, Central Kalimantan, on August 24, 2005. The villager claimed to have bought Pong four months prior from an oil palm plantation worker, whom we suspected had killed Pong’s mother.

He was two years old and weighed 8.6 kilograms upon arrival at Nyaru Menteng. He was in poor condition – with sparce hair, suffering from malaria and typhus – and was placed in quarantine until he fully recovered.

Following his quarantine, Pong joined the Nursery Group and later passed through all stages of Forest School. Pong progressed well and on April 7, 2017, was moved to Kaja Island. During his time on Kaja, he further developed his skills and became an active individual.

Pong is now 15 years old and weighs 41.5 kg. His cheekpads are developing and he is ready to live as a true, wild orangutan in the Bukit Baka Bukit Raya National Park.


Rutan was rescued from a villager in West Kalimantan on January 7, 2006. She was around three years old when she arrived in Nyaru Menteng and weighed 10 kilograms.

Following her quarantine, Rutan joined Forest School, and completed the final level in 2009. In 2016, she was moved to Bangamat pre-release island, where she became a good explorer who preferred to avoid humans.

Rutan is now 15 years old and weighs 32.3 kg. After 12 years of rehabilitation in Nyaru Menteng, it is time for Rutan to live as a wild orangutan in the forests of Bukit Baka Bukit Raya National Park.


Agis was rescued on April 22, 2006, by a joint team from the Central Kalimantan BKSDA and BOSF Nyaru Menteng. A resident of Kuala Pembuang, Seruyan Regency, Central Kalimantan, had kept and treated her like a human child for seven months. She was two and a half years old, weighed 6.6 kilograms, and was suffering from dehydration and malnutrition.

In Nyaru Menteng, Agis completed quarantine before joining Forest School. She passed all levels and entered the pre-release stage of rehabilitation on Bangamat Island in 2014. She was then moved to Kaja Island in 2015.

Agis is very good at adapting to new surroundings and easily socialises with other orangutans. She has a gentle nature, yet is capable of defending herself when required.

Now she is 14 years old she is armed with the survival skills she needs to begin her new life in the Bukit Baka Bukit Raya National Park.


Jaka arrived at Nyaru Menteng on January 3, 2007, after being rescued from an oil palm plantation worker from PT. Bumi Sawit Kencana, in Sebabi, East Kotawaringin Regency, Central Kalimantan. He was two years old and weighed 10 kilograms.

Jaka successfully passed through quarantine and joined Forest School. At first, he experienced difficulty in learning new skills and was not as active as his peers. However, he was quick to adjust and began displaying natural behaviours, which helped him complete Forest School. On March 28, 2016, Jaka was moved to Bangamat pre-release Island, where he was known as a highly curious, independent orangutan.

Jaka is now 13 years old and weighs 41.7 kg. With his skillset and abilities, he is more than ready to live in his new home – the forests of Bukit Baka Bukit Raya National Park – alongside Pong, Rutan, and Agis.

30 Days Search of Orangutans


Successfully releasing orangutans is a lot more complicated than simply opening cage doors and setting orangutans free in the forest. Preparing orangutans prior to their release can take more than seven years and once they have finally been released, our Post-Release Monitoring (PRM) team take over. Their primary task is to follow, observe, and collect data daily on the released orangutans for a full month post-release. Our PRM team tracks individual orangutans from the time they wake up and leave their nest in the morning until they build a new night nest. These dawn ‘till dusk follows are known as a nest-to-nest observations. The behavioural data collected is then used to assess and evaluate the individual orangutans adaptation to natural forest and also to evaluate our rehabilitation process within our care centres.

Nest-to-Nest Observations

All of our PRM teams, in the three forests in which we work, leave camp before dawn to ensure that they are at the night nest before the orangutan wakes up and starts his or her daily activities. Once the orangutan is awake, the team begins to record data on what the orangutans eats and does, where it travels and where it sleeps. They have to work hard to keep up with orangutans as they travel swiftly through the trees, while dealing with often challenging terrain on the ground. Sometimes it is not possible to complete nest-to-nest observations over an entire 30-day period, especially when orangutans disappear into the forest leaving no trace of their whereabouts.

The PRM team heads out on patrol

To continue 30-days of observations, even on the individuals that disappear, our team conducts patrols along transects that the orangutans are most likely to visit. Recently, our PRM team in Nles Mamse Camp, Kehje Sewen Forest has managed to find and observe several individuals that were released in December. Which orangutans did our team catch up with, and how are they doing in the forest? Find out more in our next story!

Ung: Ninja of the Kehje Sewen

Every day our post-release monitoring teams based in the forest work hard to observe and record behavioural data on the orangutans we have reintroduced. Last week, our team at Nles Mamse Camp prepared to head up north to the river delta in the Kehje Sewen Forest. It had been a week since the team had last visited that particular transect, and they were looking forward to finding out which orangutan they might encounter.

The team departed camp in the morning, and shortly after passing Simpang Tawon detected a signal from Ung, a young adult female released on April 26, 2017. They were a bit surprised to detect Ung’s signal, because she had not been seen since September.

Ung is known as the “ninja” of Kehje Sewen, due to her active and stealthy movement. Ung has managed to disappear every time we have attempted to observe her, leaving us to rely heavily on radio tracking signals to track her down. The last time Ung was seen, she was eating and spending time in a downhill area leading to the Telen River. The team could not miss this opportunity to catch up with her.

Ung eats the forest fruit

After going back and forth along the river bank tracks a few times, Ung was found near the main trail. She looked healthy, and as restless as ever. In a matter of minutes, she swiftly crossed the shallow river via the rocks and overhanging canopy, and as usual left our team in her wake!

Ung the ninja of Kehje Sewen

Refusing to give up the chance to observe Ung, the team followed her across the river and checked again for his radio signal. Ung was spotted eating some fresh stems, then climbed up a tree, where she sat and ate a large amount of fruit.

Not one to sit around for too long – and in living up to her nickname – the ninja of Kehje Sewen disappeared again in the hills surrounding the Telen River. The team tried to track her, but she quickly vanished into the thick forest.

Our continuous monitoring, all the hard work and tough times are worth it, especially when you finally get to catch up with released orangutans like Ung. It is amazing to see her adapting so well to life in the forest, where she belongs.

One Week Post-Rescue, Alejandra and Rachel Doing Well

We are happy to report that the two female baby orangutans we rescued last weekend are gaining strength and recovering well.


Alejandra was rescued on December 22, and came to our centre a little weak; however, medical examinations determined she was actually in good health. At approximately 3-4 months old, Alejandra was unable to sit, but is now learning to sit properly under the help and care of a babysitter. She looks happier, and has begun to adjust to her new surroundings and to our babysitters. Now weighing 2.5 kg, Alejandra loves drinking milk, and has started eating soft fruits to increase her nutritional intake.


The following day (December 23), another baby orangutan was handed over by a local villager, not far from where Alejandra was rescued. Rachel was brought to Nyaru Menteng in a wooden box, and upon her arrival was slightly intimidated of new faces. However, over the past week Rachel has adjusted very well and is now interacting positively with her substitute mother – one of our dedicated babysitters. Estimated at around 12-18 months old, Rachel weighs 8.3 kg and loves fruit and milk. She has already tried some of the enrichments on offer in the baby house, and even enjoys climbing trees of a certain height.

Alejandra and Rachel are the 23rd and 24th babies currently being cared for in the BOSF Nyaru Menteng baby house. Both babies will undergo a 2-month quarantine period prior to joining the nursery group. Thanks to the dedication and loving care provided by the Nyaru Menteng team, Alejandra and Rachel are now starting to build confidence, and are on the road to recovery.

We have high hopes these two babies will pass quarantine, and soon join all the other babies in the nursery group. We’ll help you get there, girls!

A Mother’s Day Salute to Our Babysitters

In Indonesia, Mother’s Day falls annually on December 22 – a day when we celebrate our mothers, and express our deep gratitude for their unconditional love, care, and support. On this day, we should also acknowledge mother figures, like the babysitters at our rehabilitation centers, who take on the role of substitute mothers to rescued and orphaned baby orangutans. The dedication of our babysitters, and their contribution to orangutan conservation, greatly influences development in our orangutan babies.

When a baby orangutan is rescued and brought to a BOS Foundation quarantine facility, our babysitters immediately assume the role of surrogate mother, and take on the responsibility of caring and raising the baby. Babysitters form a close bond with the orangutans in their care; they give them love, help them overcome the trauma they have suffered, and help build their confidence.

A long rehabilitation process, with a lot of ups and downs along the way, is required before an orangutan has mastered the skills needed to survive in the wild. Over several years, a babysitter must nurture the babies in their care, look after them when they fall ill, and support them as they progress through the stages of childhood.

“The best experience in taking care of orangutans is that we get to watch them grow, and then see them finally get released in the forest,” said Eka, a BOS Foundation babysitter.

Every mother wants the best for her children, and our substitute mothers are no different; their greatest hope is to see the orangutans they have raised living wild and free in a natural, protected forest.

On this Mother’s Day, we would like to salute our hard-working babysitters for their dedication and contribution to the orangutan conservation effort. Thank you for all your guidance and patience, and for the love you have showered on so many orphaned orangutans!

Awesome Teamwork For A Successful Release!

Releasing orangutans to their natural habitat follows a very long and intense rehabilitation process. Rehabilitated orangutans must have mastered many different wild skills before they can be considered for release. They must be in good health, be of suitable age, and exhibit appropriate natural behaviours. The entire BOS Foundation team is involved in the lead-up to a release – team members at the release-site camp, staff at the rehabilitation centers, and those manning the Bogor headquarters are all kept busy carefully planning and preparing the event to ensure it will run safely and smoothly.

Eagerly Awaiting Every Orangutan Release!

At the end of November, rain fell daily on the Kehje Sewen Forest. Plant-life thrived and sprouted to form overhanging bushes along the transect trails. The rivers rose and the air felt cool and damp after every downpour. The wet conditions failed to dishearten our PRM team, and the crew from the Nles Mamse Camp welcomed a damp December with its promise of another orangutan release. This latest release, the 14th conducted in the Kehje Sewen Forest, following the release on July 12 (read the story here). This time, we eagerly looked forward to seeing five orangutans, each having completed a long rehabilitation process at Samboja Lestari, finally gain their freedom.The PRM team worked hard with preparations, starting with a field survey to determine the exact release points. Where and how we release orangutans depends on different factors including the individual characters, who they are used to socialising with, and the availability of natural food sources. Mother-offspring pair Ingrid and Ivan, were of course released together, since 4-year old Ivan is still heavily dependent on his mother. But for the three other orangutans, these were released at different points.The team also checked Mugi’s dock from time to time, to monitor the boat construction work being undertaken. When finished the boat will be used to carry orangutan transport cages and release team members across the Telen River.

The PRM team also worked hard at cleaning the dock, installing some new railings, and fixing steps for added safety.

As the release day approached, PRM team members at Nles Mamse Camp, were kept busy cleaning the camp and surrounding yard, and preparing logistics to welcome the orangutans and the incoming release team.

Our team kicked into high gear to prepare for the release and their hard work and dedication paid off. The release went smoothly, and the five orangutans are now living free in the Kehje Sewen Forest. What an awesome outcome for another terrific team effort!

We will continue to monitor and observe these five for the coming months, as they experience life in the wild for the first time. Stay tuned, and look out for our stories and updates on their adaptation, coming soon!

BOSF Farewells 2017 with Release of Eight Orangutans


As the year comes to an end, the BOS Foundation is still working full steam ahead on its #OrangutanFreedom campaign. With 2017 marked as “The Year of Freedom for Orangutans”, the BOS Foundation has worked tirelessly throughout the year to successfully free 170 orangutans from the Nyaru Menteng rehabilitation centre in Central Kalimantan and Samboja Lestari in East Kalimantan, both to pre-release islands and to natural forests.

The BOS Foundation, in collaboration with the Ministry of Environment and Forestry, is seeing out 2017 with the release of eight more orangutans from Nyaru Menteng to the Bukit Batikap Protected Forest, in Central Kalimantan. This is the 13th release conducted by BOSF Nyaru Menteng in Bukit Batikap since 2012, and the 20th overall in Central Kalimantan. This will bring the total number of orangutans released to the Bukit Batikap Protected Forest to 175 individuals.

Day of Freedom for Orangutans

The eight orangutans in this release included seven adult males (Sabun, Kasper, Mas, Dani, Jaki, Bento, and Fitun) and one female (Karen), who departed Nyaru Menteng in two batches. The first group set off on December 12, with the second group following the next day.

The first batch of orangutans – Sabun, Kasper, Mas, and Dani – were sedated at Nyaru Menteng on December 12, and carefully placed in transport cages. At around 8 p.m., the team and the four orangutans left Nyaru Menteng and headed to the Kuala Kurun Airstrip, in Gunung Mas Regency. The team arrived at the airstrip at midnight, and took a break before flying out the next day to the release point. The helicopter used was made available by the Directorate of Forest and Land Fire Control, from the Ministry of Environment and Forestry (KLHK).

Luckily, we were blessed with fine weather all morning. Two orangutans were flown at a time, to comply with maximum loading capacity. Sabun and Kasper departed first on the morning of December 13, and quickly embraced freedom after their cages were opened at the predetermined release point of Monnu reef, deep in the heart of Batikap. Mas and Dani got their turn in the afternoon, after waiting for the helicopter to return and airlift them to the forest.

Meanwhile, back at Nyaru Menteng on the very same day, the second batch of orangutans were undergoing sedation in preparation for their journey to freedom. Jaki, Bento, Karen, and Fitun left Nyaru Menteng on December 13, and arrived at the airstrip to be flown and released today (Thursday, December 14).

These eight orangutans are now enjoying their first moments of true freedom in the Bukit Batikap Protected Forest. What a wonderful way to end a very busy year!

Orangutan living wild and free in Batikap

Thanks to the cooperation and support from both the local and central governments, institutions, and partners from all over the world committed to the conservation of orangutans and their habitats, the BOS Foundation has given freedom to 326 orangutans since 2012! We are grateful for the moral and financial support of all parties that have contributed to this conservation effort. Let’s continue to work together to ensure orangutan and habitat conservation, to preserve this beautiful and amazing species!
