17th November 2016

Wednesday, November 16th 2016, an isolated young female Sumatran orangutan was rescued by a team from the Sumatran Orangutan Conservation Programme (SOCP) and the Aceh Conservation Agency (BKSDA Aceh) of Indonesia’s Ministry of Environment and Forestry, from a tiny fragment of forest surrounded by palm oil in the Tripa peat swamps, part of the world renowned Leuser Ecosystem in northern Sumatra, Indonesia.

Located in a palm oil plantation near the village of Gelanggang Gajah (Kuala Batee sub-district, Aceh Barat Daya district, Aceh province) the orangutan first had to be captured from the tree tops by the team, which included SOCP veterinarian drh Pandu Wibisono and SOCP Operations Manager Asril, using an anaesthetic dart fired from a specially designed rifle. The task was made easier, however, by the fact that there were only 4 small trees for her to hide in, all other surrounding vegetation being 4 year old oil palms, only a few metres high.

On being successfully darted at around 11.00am, and then caught in a net as she fell from the tree she was in, she was found to be around 7 years old and weighing only around 20kg, a clear sign of her malnutrition due to having almost no natural food available.

As Asril commented, “normally we don’t want to capture wild orangutans but in exceptional circumstances we feel we have no choice. In cases where we know the animal is going to die or be killed if we don’t get them, then of course we do our best to get them out of there and move them to somewhere safe. This young female, who we’ve now named ‘Zaskia’, was already raiding farmer’s crops, and even eating young palm oil seedlings in an attempt to survive. That’s certainly not their natural diet, but it’s all she had to try and survive on, and if we hadn’t got her out of there soon the villagers would almost certainly have killed her for the damage she’s been causing.”

Once safely sedated and in the net the team performed routine medical checks and transferred Zaskia to a specialist transport cage ready and waiting on a pick-up truck 2km away from the capture site.

“Despite being obviously undernourished there were no signs of any other major medical problems,” stated drh Pandu Wibisono, SOCP veterinarian. “That being the case we left at 14.00 and took her straight to the SOCP’s orangutan reintroduction centre in Jantho, Aceh Besar, in a strictly protected Nature Reserve with abundant natural food in the forest, where she will join over 90 other orangutans already released there,” he added.

Dr Ian Singleton, Director of the SOCP also commented, “capturing free living wild orangutans  goes against the logic of the conservation goals we are trying to achieve, to keep as many wild orangutans living free in their natural habitat as we possibly can. But in cases like Zaskia’s, where we know she will be killed we really have no choice but to try and help them. Fortunately though, we are also reintroducing confiscated illegal pet orangutans back to the wild in Jantho, the aim being to establish an entirely new genetically viable and self-sustaining wild population of this Critically Endangered Species. Whilst its always sad that we have to capture and rescue wild orangutans like this one, the up side is that she is now joining the new population, she will probably live a long life in the wild there and hopefully she will produce several infants during her lifetime, making a major contribution to the new population being established in Janthoand therefore the long term survival prospects for her species! That’s something she would not have done if she’d stayed where she was.” He stressed.

Genman Hasibuan, S. Hut. MM, Head of BKSDA Aceh added, “Sumatran orangutans are a legally protected species in Indonesia, with fines of up to Rp 100,000,000 and prison terms of as much as 5 years for anyone caught killing, capturing, keeping, or trying to sell one. We have already prosecuted a number of people over the last few years and will continue to do so if the illegal capture and killing of orangutans does not stop. We hope these prosecutions will act as a deterrent to anyone thinking of capturing or killing an orangutan and for anyone who is offered one as a pet.” He emphasized.

The Tripa peat swamp forests and the Leuser Ecosystem in which they lie have both been in the news regularly over recent years. Tripa came to the worlds attention in 2012 when huge fires ripped through large scale oil palm plantations, devastating local biodiversity and releasing huge amounts of carbon into the atmospehere. These events led to several legal challenges against the companies by local NGO’s and by Indonesia’s Ministry of Environment, resulting in large fines and prison terms being handed out to the offenders. The 2.6 million hectare Leuser Ecosystem is also the subject of a civil lawsuit against Indonesia’s Ministry of Home Affairs and the Governor and parliament of Aceh province, due to fact that despite it being a National Strategic Area under National Law, which then requires its inclusion in all levels of spatial land use plan, it is not mentioned at all in the Aceh provincial spatial land use plan a fact that both National and provincial government already acknowledge renders the plan an illegal document.

Local NGO’s and environmentalists are now pushing the central government to ensure that all fines and prison terms related to the Tripa peat swamp palm oil companies are now enforced and carried out. They are also eagerly awaiting the outcome of the civil lawsuit against the Aceh spatial land use plan, originally due on November the 8th but then postponed until the end of the month.

PRESS RELEASE : Four Sumatran orangutans return to Aceh for release to the wild.

Four Sumatran orangutans return to Aceh for release to the wild.

16th November, 2016

From : Balai Besar KSDA Sumatera Utara and PanEco Foundation – Sumatran Orangutan Conservation Programme

On Tuesday November 15th, four young Sumatran orangutans arrived safely in the forests of Jantho, Aceh Besar, to begin the process of learning to be wild orangutans once again. They travelled to Jantho overnight from their previous home at the Sumatran Orangutan Conservation Programme’s orangutan quarantine centre in Sibolangit, near Medan, in North Sumatra.

Agustina, a female approximately 8 years of age, and 3 males, Adel, Jagai and Upin, between 5 and 7 years old, arrived at 11.00 in the morning at the Jantho Orangutan Reintroduction Centre, also run by the Sumatran Orangutan Conservation Programme (SOCP).

“I wish these four orangutans the very best of luck for the future as they learn the skills they will need to survive in their new habitat,” commented Dr Hotmauli Sianturi, Head of the North Sumatra Conservation Agency (BBKSDA Sumatera Utara) of Indonesia’s Ministry of the Environment and Forestry. “All being well they’ll produce infants of their own eventually so help to found the new wild population of this critically endangered species being established in Jantho’s forests.” She added.

According to Mukhlisin, Manager of the Jantho orangutan Reintroduction Centre for the SOCP, the four young orangutans must first spend a few more weeks in cages at the edge of the forest on the banks of the Aceh River.

“First they have to recover their energy and get used to their new surroundings,” he noted. “They’ll then be released and closely followed and monitored in the forest for several months by the staff at the centre. The staff will observe the orangutan’s progress closely and monitor their health, diet and behavior so we can assess how well they’re doing. If they need any help from the team, such as extra food, or to shelter for a while in the cages again, then we will provide that. Most orangutans we release do very well out in the forest and don’t need much help at all. The most important thing for them is to find enough food and to sleep in a well-constructed nest in the trees for protection against predators and to prevent them getting too wet and cold if it rains.” He added.

Dr Ian Singleton, Director of the SOCP also commented. “These orangutans were once illegal pets in Aceh, confiscated from their owners by the Ministry of Environment and Forestry’s Conservation Agency in Aceh (BKSDA Aceh). They have since been cared for and rehabilitated at the SOCP orangutan quarantine centre near Medan. Now they’re finally ready to return to their natural habitat and have a second chance at a long and healthy life as a wild orangutan once again. It’s really great to see orangutans like these, after suffering the death of their mother when captured and then kept illegally, often in tiny cages or chained by the neck, get the chance to be genuinely free and wild again. Orangutans can live for 50 years or more in the wild and we wouldn’t want them to spend the rest of their lives in metal cages. They will also be joining over 80 orangutans that have already been released in Jantho. The aim is to establish an entirely new, self-sustaining wild orangutan population in Jantho, as a kind of ‘safety net’ to prevent the extinction of their species in the wild.” He explained.

Genman Hasibuan , S. Hut. MM, Head of BKSDA Aceh added, “Sumatran orangutans are a legally protected species in Indonesia, with fines of up to Rp 100,000,000 and prison terms of as much as 5 years for anyone caught killing, capturing, keeping, or trying to sell them. We have already prosecuted a number of people over the last few years and will continue to do so if the illegal capture and keeping of orangutans does not stop. We hope these prosecutions will act as a deterrent to anyone thinking of capturing or killing an orangutan and for anyone who is offered one as a pet.” He emphasized.

Dr Hotmauli also stressed, “Whilst it really is heartwarming to see orangutans like Agustina, Adel, Jagai and Upin on the path to being truly wild orangutans once again, that they are captive in the first place is also a sign that we are failing to protect them sufficiently in the wild. Each one of these four youngsters will have been removed from the body of their dead or dying mother, almost certainly killed by human hands. It’s that and the destruction of their habitat that remains the biggest problem!”.

Drh Yenny Saraswati, Senior Veterinarian for the SOCP added, “So far these four orangutans have done very well. We managed to get them back to full health and also to teach them how to be orangutans once again after living with people. Now their future is very much in their own hands. We wish them the very best of luck and will continue to do all we can to ensure they have a long, happy and productive live back in the forests of Aceh.”

  1. 4 orangutan to Jantho

From Cage to Nest – Happy 5th Birthday Ganteng!

21st January, 2016 
Written by Jessica McKelson, SOCP. 

WATCH NOW! DECEMBER 2015 – Ian & Jess visit Ganteng and follow his progress.

“To be honest it’s actually amazing to me that both Gober and Ganteng are now living free as wild orangutans in Jantho, Aceh. Back in 2011 when the twins were born, Gober was still totally blind, and we never expected she would again be free in a forest. That changed completely when we were able to do surgery on her cataracts. I remember very well the birth of the twins too. We knew Gober was pregnant, and due any day, but had no idea that she’d present us with twins. The only downside is that poor little Ginting didn’t make it this far, even though when Ganteng was left behind we all thought it would be Gober and Ginting that would be the big success story, not her twin brother. But still, like I said, theirs is an incredible story, and, despite the sadness, also a very positive and heartwarming one. Gober, who we always knew was elderly, gets to live out her days in a spectacularly beautiful and rich forest, much better in fact than where she first came to us from. She might even be pregnant again already, we are not sure. And now Ganteng is also making really excellent progress as a wild orangutan. So happy 5th birthday little guy…..and I hope there are many many more truly “Wild Birthdays” to come!”
Ian Singleton, Director SOCP.


Wow! 5 years ago today (21st January 2011), Ganteng and his sister Ginting were born at SOCP’s Quarantine Station to their mother Gober (their father was Leuser). Time has flown by! Even now, I can remember watching the two twins for the first time as they clung to Gober, and how absolutely terrified they were of the humans in front of them. gober, ganteng, ginting (6)

Today, on Ganteng’s fifth birthday, I dedicate this piece to his sister Ginting, who would have also turned 5 years old today, however, tragically, we found her passed away in the forest due to natural circumstances (age 4). Ginting’s legacy will always be remembered every time we see Ganteng.

It is crazy to think that just 12 months ago, Ganteng was released back to the wild, he did not follow his mother and sister, instead, he ended up spending the next few months in the pre release cage alone, scared of the forest, and terrified of climbing trees. I reflect on how far Ganteng has progressed in the last 10 months I’ve been working with him and the team in Aceh to ‘train’ him for an eventual life back in the forest.

Wow, life has changed dramatically for him!

I am thrilled Ganteng has taken to the animal training program so well and can now confidently say that he is behaving like a wild orangutan; I am honoured to be a part of Ganteng’s life and I am so proud of the team in Aceh who have worked so hard on implementing the steps to make it possible for Ganteng to return to the forest.

The best birthday present we have given him is the opportunity to be free, to learn about the forest, to meet and to follow his new wild cousins and to be a wild orangutan. His survival success now rests with himself. Although he’s doing so well, we will continue to monitor him daily, and I silently pray that his mother Gober will end up passing by and they will reconnect. (Dreaming big!)

Happy Birthday Ganteng! A brave little orangutan and a hero in the Sumatran orangutan world!

Ian & Jess’s Journey: December 2015

image_1SOCP Director Ian Singleton and myself have just returned from four days at Jantho Reintroduction Centre in Aceh Besar. It had been over 10 months since Ian last visited Jantho to release ‘Gober’ and her twins, ‘Ganteng’ and ‘Ginting’. I was excited to show Ian Ganteng’s progress, and also to look at commencing a new training program for another candidate, ‘Lucky’. I was also anxious to see how Ganteng was getting along, as when I last left him he was just starting to learn how to build and sleep in nests by himself about 50-100m from the pre-release cage area.

Arriving at Jantho:

The road leading into Jantho was extremely muddy as it is the rainy season. Torrential downpours each afternoon leave the bumpy track almost impassible and getting bogged down is just part of the journey into camp! After finally arriving, all I wanted was to head straight into the forest in order to find Ganteng, so, Ian and myself quickly headed off in search of the staff monitoring him around 1km away from camp.

I’d heard from the team’s regular updates that over the last month the young male had developed an incredible confidence to explore while following a group of his fellow released orangutans in an area of high fruit density. Ever since my previous month’s visit, when I pushed him to move away from the cage location, the monitoring team had also observed him building nightly nests and sleeping in them away from the cages. Ganteng was still was coming down three times a day to get supplementary food from the staff, which is important to give him a healthy, balanced diet, as we slowly wean him onto eating only forest foods.

Approaching Ganteng’s location in the forest, I was excited, but also a little nervous about how Ganteng would be doing. Actually, it was very difficult to spot him high up (20m+) in the fig trees with his friends, so it took a few hours to fully assess his condition. How wonderful to watch him behaving like a wild orangutan with no interest in coming down to people. Fantastic result!

My only concern was that Ganteng might get sick from sleeping in the forest, as torrential downpours each afternoon and night lead to dramatic temperature drops overnight. Only time will tell how the young orangutan will adapt to these rainforest extremes.

Our Time at Jantho:

For three nights, Ian, myself, and the staff observed Ganteng behaving like a wild orangutan. Each morning the staff would meet back at the nest he’d constructed the night before, wait for him to wake up and then follow him throughout the day. He was feeding in many fig trees, eating other wild fruits, and munching on leaves from a number of orangutan food species.

It’s still key for Ganteng’s development to be around other orangutans, so it was great to see him interacting with other individuals! While we observed, he would follow them, staying close, and learning all about how to be a wild orangutan; which trees to feed in, how to manipulate the fruits, who wants to play, and what are the best times to be social. Not once did he retreat back to the pre-release cage area, instead choosing to stay in the forest with his friends. This has been a huge development from the training program; we are witnessing natural learning, dispersion and exploration, where Ganteng’s key teachers are the orangutans, which have been released, instead of spending long periods in the Quarantine – they’re wild animals.

It was extremely hard to get any good footage of Ganteng, as he was always so high up in the canopy, often out of sight feeding and nesting. But witnessing him build a nest each night and behave like a wild animal was extremely rewarding.

What have we learnt from training Ganteng?


Photo Jess McKelson, SOCP – ‘Ganteng’

  • Ganteng learnt how to build a nest in a cage, and we weren’t sure if he’d be able to apply these skills in the forest. It took some time, and some pushing for him to bend, break, and shape tree branches into an orangutan’s characteristic nest. Now, although he is not a perfect nest builder, he is able to build a nest high up in the trees. One of the most important behaviours of a wild orangutan!
  • Ganteng is a 5 year old which is attracted to following other orangutans no matter what sex they are. He often follows his friends; learning forest pathways, and a variety of feeding behaviours. Interestingly, we have also noted that he is teaching others the feeding behaviours he’s picked up from his broad range of orangutan interactions. For example, he has been observed showing orangutans how to eat termites and feed on different leaf species, both of which make up an important part of the wild diet. These orangutans then eat these foods the next time they encounter them, even without Ganteng present. Wild social transmission in action!
  • Ganteng’s training with the staff is well developed, as they are able to call him down and move him to other trees when the pathways become too difficult or he has ranged too far from his orangutan friends. We think it is critical to keep him around other orangutans and manipulate his movements, and by using his diet we are able to ensure he is kept in contact with them. Yet he is still able to connect with the monitoring staff when we feel he is unable to resolve an individual problem.

Amazing work from everyone on the monitoring team!

Training Ganteng. Abandoned twin orangutan, returns to the wild in 2015.

23rd November 2015
Written by: Jessica McKelson, Pan Eco Sumatran Orangutan Conservation Programme (SOCP)

It’s November 10th 2015, and I’m back in Jantho Reintroduction Station, Aceh. I’ve just had 2 months break in Oz, so the last time I visited was early August. I love it here; it is where I get to escape from the busy life of Medan City in North Sumatra, where I get NO mobile phone service and am not required to answer emails and be ‘on call’ 24hrs a day. It’s where I get to witness all our released orangutans returning to their rainforest homes.

Surrounded by a mixture of grasslands and spectacular rainforest habitat, our station is nestled within the highest protected status ‘Cagar Alam’ and therefore suffers very minimal disturbance from illegal activities. I’m sat with the river on one side, watching the otters feeding as they pass our release site. They remind me of meerkats, the way their heads bob up and down in the water checking up on us as they swim past. Towards the forest, I also watch our recently released orangutans, Genang and Monic, feeding on fig tree fruit about 100m from the release cages. Last time I saw them, they were in cages at Quarantine, and it gives me immense joy to witness their wild existence once again.

Checking up on released animals is one reason for my monthly visits, but what I have really been working on since February is the Animal Training Program for a young male twin, Ganteng, and his friends, Mikki, Rachmad and Lucky. I reminisce about the program and how far we have come since March. Ganteng has progressed far more quickly than I could have ever imagine and the past few months have taught me a great deal about juvenile orangutans and training them back into the forest. How fast they can adapt when released role models are a part of the training program along with staff who can help build the confidence and independence (the first steps required) for the animal to be free once again.

Ganteng’s Story

Back in February, I visited Jantho Reintroduction Station and was amazed to see the release efforts going from strength to strength. But I left feeling bothered about Ganteng and his development. He was a different animal from the one I’d worked with at the Quarantine Station; he had a different attitude, showed some sterotyped behaviours (possibly stress driven) and seemed to be simply ‘lonely’. After discussions with SOCP’s Director Ian Singleton, I realised here was an opportunity to put my past animal training experience to good use. This time though my training challenge would be much more complex and have a large load of past baggage to sort through.

Ganteng’s story is heartbreaking. He was one of a pair of twins born into captivity to a wild orangutan, Gober, who was blind but had her sight repaired by surgery. Despite being born in captive environment, Ganteng is quite wild as he stayed with his wild mother and twin sister, Ginting, and never interacted with people. For his future returning to the forest it was the best not to condition him to people and to let him learn from a wild orangutan, his mother. However, when the three were released at Jantho, his mother and sister, left him behind in the forest, where he spent the night alone for the first time in his life, sleeping on the ground.

Watch the video on release efforts of Gober, Ganteng and Ginting HERE

Tragically Ginting’s body would be found just a few months later by SOCP Jantho staff and myself on a visit that will never be forgotten. Our thoughts are with her everyday.

Read more from SOCP Dr Ian Singleton, HERE.

I can only imagine how this experience must have affected Ganteng. His first and only memory of the rainforest was his family leaving him behind. He never climbed a tree and was never taught how to move around a forest by his mother. After that harrowing night asleep on the forest floor, humans surrounded him and brought him back to an empty cage. Training him looked to be impossible, as a 4-year-old orangutan, he should still be learning from his mother; he had no trust for people, showing signs of stress whenever SOCP’s keepers tried to work with him. Furthermore, he’d had no interaction with orangutans except his family, and he’d need to learn all of these social skills, as well as how to be a wild orangutan. He was left by his mother, lonely and afraid, and not in any condition to leave the pre-release cages unless these insecurities were broken down.

I am a firm believer of ‘reduced human contact’ for orphaned orangutans; therefore everything we do at Quarantine is non-human contact or very limited human contact. Even at the very young age they arrive, while orangutans may have some hands on comfort from vets and keeping staff, they are quickly ushered into social groups so they can develop confidence and learn skills from each other. In this way we try to teach them how to be as wild as possible in a captive environment; they spend all day with other orangutans, and sleep in hammocks filled with leaves, not in washing baskets, or with people or on the floor in any shape or form. It is the best and ‘kindest’ form of teaching if you want to return them to their forest home.

However, there are some orangutans at quarantine that are very human focused, due to the previous hands on care and attention they have received from their illegal captive days and also with previous Quarantine keeping staff who used to sleep with the small orangutans in the vet clinic. These animals require special care, as they will take longer to become ‘wilder’ and it’s not possible to take them from all human care and throw them straight into social groups. Actually, I think it’s cruel to ‘fuss and over comfort’ infant orphans when they arrive at Quarantine, and would only have a negative impact on their development. The results we have seen from the new orphan arrivals at Quarantine have been outstanding, so I thought it would be possible to develop a methodology of Operant Conditioning practices towards Ganteng’s development.

As you can probably work out, these previous experiences, challenges, and individual orphan cases have made me very motivated to develop Animal Training Plans for captive orangutans (Quarantine) and for the rainforest (Jantho Reintroduction Station, Aceh).

It all started with Ganteng, my biggest ever challenge, with so much unfortunate history and anxiety to work on. I needed to design a training plan that would prepare Ganteng for the forest; one that would include meeting other orangutans so he could learn the skills to be a wild orangutan, but also keep him safe until he was independent and ‘ready’ to venture off on his own. Not only did the responsibility for his future cause me great stress, but also I would be working with staff unskilled in animal training. What would the best option be? I had to trust my past skills and my gut instinct. Each day will be a different adventure!

Stage One: Operant Conditioning

For me, the most critical part of the training program was to develop a trusting, healthy relationship with Ganteng. We needed to enter his space and develop a rapport with him. There would be no use opening the cage and allowing him to explore by himself if he had no idea what to do and had no trusted friends to guide him along his journey.

In April we nominated three staff to train Ganteng, to give him the same people to work with every day. Each orangutan is different and each will respond differently to conditioning, but we could maximise the training’s effectiveness by keeping his conditions stable and consistent. The staff also needed to learn patience. Over three long days I worked closely with the training staff, critiquing them on how to feed Ganteng in his cage, slowly conditioning him to only feed with people giving him his diet. This was an absolutely critical first step for the operant conditioning to succeed.
Initially I set a goal of 3-weeks, by the end of which Ganteng had to confidently come to people when his name was called, and to be hand fed at all times. He was not to be nervous or to show any signs of abnormal stress or anxiety.

The staff worked fantastically hard and within a week Ganteng began to consistently come to people when being ‘cued’ to do so. The first step on his journey back to the forest was beginning

During April it happened that a wild, adult female, Meysin, who’d been released 12 months prior, returned to the pre-release station looking slightly underweight. I decided to put her in the cage next to Ganteng. This decision would shape not only his future, but also potentially everything we do to train reintroduced orangutans.

Putting a wild female next to Ganteng was controversial, many of you reading may disagree with this step; certainly the monitoring staff did, and it took me a long time to convince them that it was best for the training and welfare of Ganteng. My feeling was I could keep her in the cage, well fed to get her weight back up, all the while introducing forest fruits and leaves to Ganteng while he had another orangutan to learn from.

During the month of April I visited twice. The second time was to introduce Meysin with Ganteng to one another so he could play and develop his social skills that can only be learnt from other orangutans. She could be a perfect surrogate mother for him, but we needed to move slowly; I did not want Meysin to become frustrated with a 4-year-old orangutan that always wants to play and interact, steals food, and invades her space. The two would be separated for periods of the day, at feeding times and at night, but otherwise mostly left to interact. The introduction went well and after a few days Ganteng came to treat Meysin as the dominant, older animal. Eventually, Ganteng began to sleep in her nest overnight and became the adopted son I’d hoped he would. This experience and companionship improved his confidence dramatically, allowing us to move to the next vital stage: introducing the rainforest and trees into his life.

Going back into the forest… A small ray of sunshine!

Over the month of May, my goal for our little twin male was to get him into the forest school setting, which would really test his relationship with the staff!

We needed to improve Ganteng’s confidence in the forest and push him to follow his trusted staff into the jungle. Once he gained the confidence to go about 20m into the forest, we would then be able to work on staying out in the forest rather than returning automatically to the cage.

As the staff pushed Ganteng into unknown areas, they would also need to teach him the pathways orangutans use in the wild. Once he’s learned these pathways, he will be able to explore the area until he is 100% confident to return alone.

To start, we set up small coconuts and plastic buckets with his food to encourage him up to climb high into the trees until he gained the self-confidence to go exploring by himself. This period of conditioning went really well and Ganteng began to get stronger, developing his muscles, allowing him to spend longer periods in the forest. He also interacted and played with new orangutan friends; Ruben, Mikki and Krisna.

This was excellent as he began to learn social skills and independence from his peers. Though he watched the other orangutans eating jungle foods around him Ganteng would still came down to his trusted staff for his diet, which allowed us to move him between the pre-release cages and the forest each day.

Releasing Ganteng

In June, we let Meysin and Ganteng out of the cages together. Automatically, the young male followed her out into the jungle. As we watched the two travel Ganteng would cry out for her and she would have to wait for him to cross the forest canopy (exactly as a mother orangutan does with her infant). We did have a number of concerns however: this was the first time he had climbed so high, travelled so fast, and ventured so far from the cage area (up to 300m); Meysin is a wild animal and might just go back to the forest where we would have no control to work towards strengthening Ganteng’s skills further. Most worrying we noted he wasn’t making a nest in the trees, a vital skill for his survival.

So, we pulled him back for another week, only letting him out each day and keeping him well trained to come back each night. We encouraged Meysin to stay around the release space by supplementing her with food, until eventually she became bored with the process and naturally dispersed. However, this time together with Meysin really shaped Ganteng’s confidence and development; her teaching him to move through the trees and allowing him to play with other orangutans in the forest was the most developing week of his entire life.

In the months of July and August I visited a further 3 times, continuing to work on Ganteng’s development in the forest. During this period we released Rachmad, a 7-year-old male. Rachmad slept outside overnight, but had a hard time acclimatising to his new surroundings. Seeing he quickly interacted well with Ganteng, I made the two complete the daily training program in the forest together. This worked well for both orangutans; it’s provided Ganteng with another role model, and is helping Rachmad gain further confidence in the forest.

I left for Australia in mid August, wondering how this entire program would progress, hoping that Ganteng would continue to improve and hoping I could apply the same methodology for future smaller orangutans. The results were outstanding to date, and there was no reason we couldn’t develop this program over the next 12 months.

Returning in November, a breath of fresh air and a proud ‘mum’ moment… Ganteng in the forest!

Black Hornbills pass over me ready to roost in the pine trees behind camp. I’ve just finished a horrendous, neck-breaking hike for 4hrs in the forest. I wanted to see on the furthest transect what orangutans I could find. I wanted to secretly find Ganteng’s mother, Gober, to see how she’s doing. I couldn’t find her, but I’m still beyond happy, sat by the river reflecting on her infant’s training program (pulling leeches off my body), thinking about how far Ganteng has come since I was last here. I’m also proud I made it back in one piece! It’s Musim Hujan – raining season. The transect trails and off path hikes make it very slippery to navigate around the forest. I often wonder, ‘what the hell’ am I doing here and why is my body tolerating this abuse. Mukhlisin Jantho Camp Manager reminds me, “Jess, you need exercise as it makes us sweat out our toxins and breathe in fresh air. You will thank me afterwards.”

Thanks for the reminder… Thanks for my ridiculous slippery hike…

As you can see in my video below, I watched Ganteng follow the staff into forest each day, during which he ate wild fruits and leaves and interacted with other orangutans. I even witnessed his natural ‘display’ towards a group of pig-tailed macaques; kiss squeaking, breaking branches and shaking the trees. This is a natural behaviour he developed alone. He was still coming to the staff for some of his diet, and they take him back to the pre release cage area for the night. The last three weeks, Ganteng decided he will no longer sleep in the cage but on top of the cage with his friend Rachmad. In this way we’ve been using his diet to reward him for moving through the trees and not using the forest floor to walk to the next tree.

I have also pushed him, because I am a negative in his world, (he doesn’t like me as I am the nasty one who pushes him back to the forest and not his comfort space) specifically by holding a broom up. I do think that one day the broom will be thrown back at me (lol)! Using this method a few nights ago, I wanted to test my big questions: What would happen if we don’t let him come back to the cages? Can he build a nest?

He did get little upset at first, but then watched his friends ‘Genang’ and ‘Monic’ build a nest and go to sleep. What made my night, and what makes this training program such an important achievement, was that Ganteng also made his own nest for the first time in the forest! Without ever having lived in the wild he performed the most important of an orangutan’s natural behaviours! After we left, he did retreat back to sleeping on top of the pre release cages, but the very next night was he no longer was sleeping on top of the cages, but in his own nest with friends Genang, Kluet and Monic in the area!!!

I cannot express how proud I am of the team implementing this training program and how hard they’ve worked with me on pushing Ganteng a little further. Through a mixture of Animal Training, consistency from staff, regular evaluations and behavioural modifications, and wild orangutan social based training, he has developed so much in the last 8 months!! More than anyone would have expected. Happy moments and a sense of achievement on a grand scale!


What’s Next?

Well we now hope Ganteng will build his nest and stay longer in the forest without wanting to come back to the pre release station. This will be evaluated daily, as he still is not confident in sleeping in his nest overnight with torrential downpours. However, when it is a nice evening he will happily stay in his nest. So its Time…. Patience…Team Work…and slow natural dispersal with his fellow friends.

Stay tuned for his next step to freedom in 2016!

PRESS RELEASE Confiscated Baby orangutans arrive safely at Quarantine Centre in North Sumatra

Monday, 16th November 2015


Sumatran Orangutan Conservation Programme (SOCP), Medan, Sumatra, Indonesia.

MEDAN, SUMATRA, INDONESIA// Three recently confiscated infant Sumatran orangutans arrived safely today at the Sumatran Orangutan Conservation Programme’s specialist orangutan quarantine centre near Medan, North Sumatra, where they will soon be given full health checks and begin the long process of being gradually returned to a life in the wild.

Investigators at the criminal detective unit of the Riau Police arrested three people on Saturday November 7th, 2015, foiling the illegal trade of these critically endangered orangutans in Pekanbaru, Riau Province, Sumatra, Indonesia.

“The first thing they need is to rest and recuperate after their long ordeal.” Stated Asril Abdullah, Operations Manager for the Sumatran Orangutan Conservation Programme (SOCP). “They are highly traumatised by all the travelling they’ve done and all the unfamiliar surroundings and people they’ve encountered these last two weeks, not to mention the initial trauma of being captured, when their mother was almost certainly killed. Being still such very young infants, that can’t have been very long ago either.” He stressed.

Riau police spokesman Adj. Sr. Cmr. Guntur Aryo Tejo said on Monday November 9th that police arrested three people from Aceh who were trying to sell three baby orangutans aged between 6 and 9 months old. “We have named the three people as suspects. One of the suspects is a civil servant from Aceh,” he said as quoted by news agency Antara.

The suspects are Ali Ahmad, 53; Awaluddin, 38; and Khairi Roza, 20.

Police received information from locals who reported that an illegal trade of orangutans was planned in the Palas area in the city of Pekanbaru, Riau Province.

Guntur said after investigating that police identified the sellers and arrested them on Saturday November 9th, while they were waiting for the buyers to meet them in their vehicle. Two of the suspects tried to flee but were later arrested after their car was involved in a road accident.

Police found three baby orangutans in the car, in white plastic boxes.

“[The orangutans] were in weak condition after a long trip from Aceh,” he said.

The suspects told police they had bought two male baby orangutans and one female baby for Rp 5 million each, in Lokoh village in District of Tamiang, in Aceh Province.

“They planned to sell the baby orangutans for Rp 25 million each. We are currently chasing the original seller in Aceh and the person who ordered them in Pekanbaru,” he added.

Police handed over the babies to the provincial Center for Natural Resource Conservation (BBKSDA) in Riau, who immediately requested the help of the SOCP to take over their long-term care and eventual return to the wild.

Ir Rinaldo, Section Head of BBKSDA Riau commented “ We would like to thank the Riau Police, WWF Riau Program, the SOCP and the North Sumatra Conservation Agency for all their assistance with this case and for delivering the orangutans safely to the SOCP Quarantine Centre in North Sumatra. At the same time, we hope this case is not repeated, and that other illegal wildlife traders, so far undetected, are also identified and prosecuted”

Head of the North Sumatra Conservation Agency (BBKSDA North Sumatra) Mr John Kennedie, expressed his appreciation to the Riau Police for preventing the illegal sale of the orangutans. “This should be a lesson to everyone that illegal trade in protected wildlife species is against the law and can be prosecuted. Furthermore, the apprehension of these traders has resulted in the rescue of these three young Sumatran orangutans, a species at serious risk of extinction. They now have a chance to recover and grow and eventually to be reintroduced to a life in the wild. For this purpose we have placed them in the care of the Sumatran Orangutan Conservation Programme, at their Orangutan Quarantine Centre, where they will receive veterinary care and begin the gradual rehabilitation process, to learn how to survive in the forest once again.

Drh Talitha Khairunisa, Veterinarian with the SOCP noted, “Whilst they seem reasonably okay at first glance they need time to rest and rehydrate after all their travels. We will give them a few days to calm down now, and get used to their new surroundings, and then give each of them a more thorough health check. Once we know they’re fit and well we will start to introduce them to some of the other young infants at the centre for companionship.”

Dr Ian Singleton, Director of the SOCP added, “We are extremely grateful to the Riau police and the Riau Conservation Agency and applaud all involved for taking such swift and decisive action in this case. Sadly, however, we’ve seen a marked increase in the numbers of very young infants arriving at the quarantine centre in 2015. This trend is worrying as it shows orangutan mothers are still being killed, and their infants taken for trade or as pets, on a regular and frequent basis. We cannot be sure yet exactly which forests these particular infants originate from, but often the killing and capture of orangutans is greatest in areas where the forests are being cleared, for example for palm oil plantations. It will be very interesting to see if the legal proceedings can identify the precise area they came from, although from what I hear it was definitely in Aceh, probably somewhere within the Leuser Ecosystem protected area.” He concluded.

Sumatran orangutans (Pongo abelii) are a distinct and separate species from their relatives in neighbouring Borneo (Pongo pygmaeus). Only around 6,600 Sumatran orangutans survive in the wild today in Aceh and North Sumatra provinces, where their major stronghold is in the Leuser Ecosystem National Strategic Area.

The Sumatran orangutan species is listed as Critically Endangered by the World Conservation Union (IUCN) on their ‘Red List of Threatened Species’, and as one of the “Top 25 World’s Most Endangered Primates.” The biggest threat to their survival is the destruction of their rainforest habitat, often for large-scale palm oil plantations, and increasing fragmentation of their habitat by roads and agricultural encroachment.

PRESS RELEASE Illegally smuggled infant Sumatran Orangutans confiscated by Malaysian Authorities return to Indonesia for return to the wild

From :

  • North Sumatra Conservation Agency (BBKSDA–SU) , Directorate General of Natural Resource and Ecosystem Conservation (Ditjen KSDAE), Ministry of Environment and Forestry, Republic of Indonesia
  • Malaysian Wildlife Department (Perhilitan), Malaysia
  • Sumatran Orangutan Conservation Programme, Medan, Indonesia.
  • Malaysian Airlines




Medan, North Sumatra, Indonesia; 20th October 2015 : Two young infant Sumatran orangutans illegally smuggled into Malaysia, today returned to Sumatra to begin the process that will eventually see them return to a life in the wild, contributing to the long term survival of this Critically Endangered species.

The two infants, a male and female, aged just around 1 year old and named Citrawan and Bobina respectively by the Malaysian Wildlife and National Parks Department (Perhilitan), were confiscated on July 24th in Bukit Tinggi, Klang, Malaysia. Four men, comprising two locals and two Indonesians, believed to be members of a wildlife trafficking syndicate, were arrested by Perhilitan enforcement officers in the 8.30 pm operation. They had been smuggled illegally into the country via Medan in Sumatra. The protected animals were meant to be sold in Malaysia by the suspects for RM 20,000 each. The case is being investigated under the Wildlife Conservation Act.

Sumatran orangutans (Pongo abelii) are a distinct species from their relative on the neighbouring island of Borneo (Pongo pygmaeus). Whilst Bornean orangutans are listed as ‘Endangered’ by the World Conservation Union (IUCN) on their Red List of Threatened Species, the Sumatran orangutan is considered the more immediately in danger of extinction, with only around 6,600 or so left in the wild today, and is therefore classified as ‘Critically Endangered’.

Today the species’ major stronghold is in the Leuser Ecosystem, straddling the border of Aceh and North Sumatra provinces in the north of the island of Sumatra. The most serious threats to their survival in the wild include destruction of their habitat, primary lowland rainforests and peat swamp forests, which is most often due to conversion to monoculture palm oil plantations, and fragmentation of their habitat by road construction, which itself leads to more encroachment and conversion and also opens access to wildlife poachers.

Infant orangutans still regularly end up as illegal pets, a phenomenon that is normally a direct result of the loss of their habitat and the killing of their mothers. Within Indonesia it is illegal to capture, kill, trade or keep an orangutan under National Law No. 5 / 1990, with potential sentences of up to 5 years and fines of IDR 100 million. The species is also listed on Appendix 1 of the Convention on International Trade in Endangered Species (CITES), under which animals smuggled out of their natural range country and confiscated should whenever possible be repatriated and returned to the wild.

Dr Ian Singleton of the Sumatran Orangutan Conservation Programme (SOCP) explained, “We are delighted to get these two little orangutans back to Sumatra, and that the smugglers were apprehended in this case and are being prosecuted. There have been far too few legal prosecutions of orangutan keepers and traders in the past, though we are seeing signs of this improving within Indonesia with two recent prosecutions in Sumatra in 2012 and 2015, and the actions of the Malaysian Wildlife Department suggest they too are also taking a stand. The main problem for the species, however, remains the loss of their habitat and the decline of the wild populations from which these two originally came.”

Ir. John Kenedie, head of the North Sumatra Conservation Agency of Indonesia’s Ministry of Environment and Forestry stated, “We would like to thank the Malaysian Authorities for their actions in this case and the SOCP for arranging the repatriation of Citrawan and Bobina. Indeed international collaboration is essential if we are to effectively address the illegal wildlife trade here in SE Asia and this is an excellent example of governments working closely with NGO’s to achieve that goal. The challenge now is to build on this and reduce the numbers of orangutans and other species still being captured and traded illegally in the region.”

Dr Yenny Saraswati, the SOCP’s Senior Veterinarian added, “We’re always glad to receive confiscated illegally captive orangutans and these two little ones are no exception. But on the one hand its sad that so many still end up as illegal pets or in the trade in the first place. but at least these two now have a chance of a full and productive life in the wild, contributing to the long term survival of their species, once they’ve passed their medical checks and quarantine period and have developed the skills they will need to survive once again in the forest.”

“Citrawan and Bobina are now recovering from their journey from Kuala Lumpur at the SOCP orangutan quarantine centre near Medan, North Sumatra and will be gradually introduced to other confiscated orangutans of the same age once their quarantine period is completed. They will eventually then be transferred to one of the SOCP’s two reintroduction centres in Aceh and Jambi, where they will join other orangutans that have already been released thus helping to build up a new wild population of this critically endangered species”, clarified Dr Singleton.

The shipment of these orangutans to Medan from Kuala Lumpur was generously arranged free of charge by Malaysia Airlines Berhad (MAB). Anita Kushairy, Head of Corporate Communications at MASkargo explained, “This is the third shipment of Sumatran orangutans that we have flown to Medan but these two are by far the youngest. As a member of the IATA Live Animals and Perishables Board, Malaysia Airlines practices strict compliance to the Convention on International Trade and Endangered Species of Wild Fauna and Flora (CITES). In line with this, we pledge our full support for international government, inter-governmental and non-governmental organizations that are managing wildlife populations and will work cooperatively towards eliminating illegal transportation of protected species worldwide and saving wildlife heritage.”
