For A New Era Of Healing

At Nyaru Menteng 2 (NM2), the road from rescue to release runs straight through our hospitals and clinic, where orangutans receive the hands-on medical care they need to survive and thrive.
This care never stops. And right now, your support goes twice as far to keep it going.

Around The Clock Continuous Care
Each patient arrives with their own story of survival.
Alejandra
When Alejandra was just six months old, she fell from a tree, badly injuring her right eye. Delicate surgery saved her life, but it was the careful daily wound care and monitoring afterward that kept her recovery on track.
Beni
When young Beni broke his leg during play, setting the bone was just the start: months of rehabilitation, gentle exercise, and regular check-ups were what made him strong again.
A frightened arrival with labored breathing may spend days on a nebulizer. A new rescue can come in severely malnourished. And just like humans, orangutans are susceptible to all kinds of illnesses.
Each story is different, but the constant is care – the quiet, daily work that keeps every orangutan strong enough to heal, learn, and eventually return to the forest.
Your support provides the medicine, equipment, and veterinary expertise that make this continuous care possible.
The Nyaru Menteng Rehabilitation Center is home to:
plus, orangutan in total
orangutans currently in nursery and forest school
orangutans on pre-release islands
Healing Is the First Step Home
No orangutan can take their first steps toward freedom without passing through the clinic doors. Here, bones mend, breathing strengthens, and energy returns. Only once they’ve regained their health can they rejoin forest school or move to the pre-release islands that prepare them for life in the wild.
By funding medical care, you’re supporting the very first step in every release story – and ensuring lifelong care for those who can never return to the forest.
Your gift today funds tomorrow’s recovery, and it will be matched, pound for pound/dollar for dollar. Donate now.
Ongoing care for every patient
Each orangutan in our care has unique needs. Some recover quickly; others live with chronic conditions that require regular check-ups, medication, and therapy for years. Our clinics are equipped to handle it all, from emergency surgeries and dental operations to malaria treatments and long-term monitoring.
This continuous cycle of care is what keeps them healthy, hopeful, and moving forward on their rehabilitation journey.
But it’s a cycle that can only continue with your help.
Medical care for orangutans
BOS Foundation’s hospitals and clinics are where emergencies become recovery stories. A frightened arrival with labored breathing may spend days on a nebulizer. A young orangutan with a painful abscess might need repeated dental work. Malaria patients require weeks of medication and monitoring.
These facilities are always ready, stocked with medicines, staffed with skilled vets, and equipped for both urgent procedures and routine check-ups.
But they only stay that way with your help.
You Can Be Part of Their Recovery Story
Your donation today keeps our clinics stocked, our vets equipped, and our orangutans cared for. It ensures Alejandra can keep her remaining eye healthy, that Beni stays strong and playful, and that every new rescue receives the treatment they deserve.
When you give, you’re not just helping one orangutan heal; you’re keeping an entire community of survivors thriving.

What we’re building… next
Enhanced Medical Care
Construction of key medical facilities, including the clinic, isolation building and microbiology lab, are ongoing. These facilities will ensure we provide the highest level of veterinary care. Orangutans suffer illnesses and injuries like humans, and their welfare is a top concern.
Expanded Sanctuary Islands
Two of the seven islands have been completed and the remaining islands are still in progress. More islands will follow once these are built so that every unreleasable orangutans can still have a high quality of life, free from an enclosure, in a forested environment as close to a natural existence as possible.
Solar-Powered Sustainability
The site is so remote that there is limited power from the grid, so clean solar energy is the best way to give us the power we need to operate. This also aligns with our commitment to sustainability. by powering the center with clean energy for years to come as well as contributing to the global shift towards renewable resources.
Education Through Hospitality
We’re building a place to welcome professional partners, special visitors, and volunteers assisting and supporting the cause. With proper shelter and facilities, our conservation guests can maximize their time at Nyaru Menteng 2.
Your donation impact so far
BOS has made significant progress already on the relocation and construction of the Nyaru Menteng 2 Rehabilitation Center. We are excited to share this progress with you.
A big move for Forest School
On 26th February, Forest School Group 4 was successfully transferred first, followed by Group 5. The young orangutans all travelled safely in transport cages without sedation. On arrival, they settled into their new night enclosures then began exploring their new Forest School the next day.

All aboard the Forest School bus
The younger orangutans in Group 2 made their journey by bus, enjoying a safe and smooth trip with their Surrogate Mothers.

Completed construction at Nyaru Menteng 2 includes:
All Forest School areas, where orphaned orangutans spend most of their time, learning to live as wild orangutans. The upgraded Forest School at NM II benefits from years of experience, with every detail designed to enhance safety, care, and to reinforce their arboreal (living in the trees) lifestyle.
Sturdy boardwalks built from long-lasting concrete and inspired by traditional Dayak design, allowing safe passage through challenging peat forest terrain.
Night enclosures where orangutans can rest securely.
Surrogate mother dormitory to support constant care.
New arboreal playgrounds and feeding platforms.

New feeding platforms that encourage a more arboreal experience
Your support funds this constant, hands-on care: the follow-up treatments, therapies, and monitoring that give every orangutan the best chance at a full recovery.
