10 Orangutans from Samboja Lestari are Going Home! (Part 2)

Following the successful release of eight orangutans yesterday, today the BOS Foundation in Samboja Lestari continued the event by sending two more orangutans to the Kehje Sewen Forest.

DNA Test : Important!

Today we were going to release two orangutans, Kent and Wani, into the Kehje Sewen Forest, after they were almost removed as release candidates due to  the necessity to re-run DNA tests.

Reintroducing orangutans is not as simple as many people may imagine. It is not only about taking the orangutans to the forest and opening their cages. Many strict criteria need to be met, both national and international and these are set by IUCN and the Indonesian authorities. One of those is to ensure the release area corresponds with the orangutans’ sub-species and origin. Hence the importance of DNA tests.

DNA tests play a significant role in deciding the location for rehabilitation and reintroduction. The placement of an individual orangutan according to their sub-species will save costs of reintroduction in the future. Following inconclusive test results, the BOS Foundation had to await more detailed analysis for Wani and Kent, who were originally candidates for this current release, along with the eight orangutans released earlier yesterday. This resulted in a delay in confirming their candidacy until after the results were out. The case of Kent and Wani shows how important DNA tests are for the government before they appoint the rehabilitation centers to care of the orangutans.

Heavy Rain in Samboja Lestari

A huge downpour had fallen over Samboja Lestari since last night until this morning. Release Teams in Samboja Lestari, Muara Wahau, and Kehje Sewen Forest coordinated nonstop to update each other with weather reports in each area. As the time passed, the weather cleared and brought hope that today’s event would go smoothly.

Just like yesterday, Medics and Technicians were ready from 5 in the morning at the Quarantine Complex. Vet Agus Irwanto as the coordinator of Release Team in Samboja Lestari, along with vet Agnes Pratamiutami were ready with the necessary sedation equipment. However, due to the rain, they had to delay the process until 09.15, still under the non-stop drizzle. Nothing could drain our spirits, though.

Kent, the independent and skilled male orangutan candidate who also dislikes human presence, was the first to be sedated.

In his enclosure, Kent seemed to start feeling the effects of the sedation. Slowly, he leaned on one of the corners, the drowsiness creeping in.

Kent started to fall asleep.

He was finally asleep and Technicians brought him out of the enclosure. Before putting him into his travel cage, vet Agus took a blood sample for the serum bank.

Kent was carried on a stretcher towards the travel cage. As always, he received a reversal shot before the door was secured.

Next was Wani’s turn to be sedated by vet Agus.

Without any delay, considering the day was getting late, Technician Firman sedated Wani. Firman is one of our senior technicians at Samboja Lestari. After looking for the right position to blow the dart, he managed to sedate Wani at 09.52.

But Wani still looked fresh in her enclosure and there was no sign of being sleepy whatsoever. After waiting for more than seven minutes, there was still no sign of drowsiness in the beautiful orangutan, the Medical Team decided to give her an extra dose. After 12 minutes, the strong female was still awake so an additional top up dose had to be administered.

Wani started to fall asleep.

Four minutes later, she finally fell asleep. Technicians brought her out of her enclosure and carried her to her travel cage.

Wani was moved into her travel cage.

Again a blood sample was taken and a reversal was given inside the transport cage. The Team tried to finish the process and leave Samboja Lestari before the weather worsened.

Constantly communicating with the Muara Wahau Team, at 10.15 the truck which carried Kent and Wani left for Sepinggan Airport in Balikpapan. After a 1.5 hour journey, they arrived at the airport where the airplane which would carry the orangutans to Muara Wahau was on stand-by.

The loading process started with moving Wani onto the plane, followed by Kent.

With loading completed, the plane was ready to fly to the ariport belonging to PT. Swakarsa Sinar Sentosa in Muara Wahau. Kent and Wani were accompanied by vet Agnes and technician Norman.

Cloudy Day in Muara Wahau

A thunderous storm poured down on the small sub-regional town of Muara Wahau which had started the night before. By 8 am this morning, it had calmed and turned into a light drizzle. The rain finally stopped at around 9 am and the sun started to shine again. But there were still many dark clouds, hanging low, promising more rain. Learning that the loading and transport process was also delayed at Samboja Lestari due to bad weather, we decided to lighten our mood by having breakfast together.  We didn’t head to PT. Swakarsa Sinar Sentosa’s airport until the team from Samboja Lestari reported that they had arrived at Sepinggan Airport in Balikpapan. It was already 11.35 am.

Weather reports from Camp 103 in Kehje Sewen Forest weren’t optimum either. It was raining as well over there. Although the sky had reportedly cleared a bit by late morning, grey clouds, thick fog and heavy rain had returned by the time the Twin Otter airplane bringing our final two orangutans – Kent and Wani – landed at the airport in Muara Wahau at 1.07 pm.

We kept our spirits high and started unloading Kent and Wani’s travel cages from the airplane and loaded them into the helicopter sling load. Weather reports from the Kehje Sewen Forest did not improve. But the B3 helicopter pilot from Hevilift, Darren Stockton, said that he was prepared to fly and see if things might look different from above. He assured us that he would try his best to find his way into the forest and take our orangutans home. However, he also earnestly told us to prepare for disappointment if he decided to turn around and return to Muara Wahau due to worsening weather conditions. Safety for people and orangutans comes above all else and whatever the pilot’s final decision would be, we would wholeheartedly respect that.

Hoping for a Better Tomorrow

Around 20 minutes later, the B3 helicopter started its engines and prepared to fly. It took off at 1.28 pm, disappearing into low-hanging dark clouds, carrying Kent and Wani to the forest. We crossed our fingers and hoped for the best.

However, after around 45 minutes, we still hadn’t received any news from our team at Camp 103. When we contacted them, they told us that the helicopter had not been sighted or heard.  They tried to radio the helicopter pilot but did not get any answer. They also informed us that the weather in forest had worsened considerably. Our hearts sank and sure enough, we heard the unmistakable sound of the helicopter coming back towards Muara Wahau.

At around 2.25 pm, the helicopter hovered above the airstrip of PT. Swakarsa Sinar Sentosa’s airport and gently lowered the sling load containing the travel cages of Kent and Wani, and landed shortly after. The pilot said that he had tried two different ways to get there. But thick dark clouds were everywhere affecting visibility. He finally decided it was not safe to keep flying and returned to Muara Wahau. Naturally, we were disappointed, but we realized it was for the best. There was no point trying to fight Mother Nature and certainly not to the detriment of safety standards.

So we unloaded the travel cages again and took them to a small forested area that borders the airport. After coordinating with all teams at the Headquarters, Samboja Lestari and Camp 103 in Kehje Sewen Forest, as well as with the teams from Airfast, Hevilift and PT. Swakarsa Sinar Sentosa, we decided that Kent and Wani will stay overnight in Muara Wahau under the careful watch of our team there and we will try to send them to their new forest home tomorrow morning.

At 4 pm, we moved the travel cages to a small but comfortable hut that usually functions as the airport’s waiting area. Vet Agnes and five technicians from Samboja Lestari are staying with our two orangutans, keeping them safe around the clock, well fed and well taken of. The helicopter also stays overnight in Muara Wahau and, weather permitting, is ready to fly as early as possible tomorrow. It was a tough day, but we are hopeful that tomorrow is a much better day.

10 Orangutans from Samboja Lestari are Going Back Home!

March 20, 2014| Orangutan Release Day 1

Today, March 20 2014, eight orangutans finally departed from Samboja Lestari towards predesignated release points in the Kehje Sewen Forest. They were divided into two groups; the first group consisted of Acul, Nila, Oneng, and Upi, and the second group consisted of Indo, Maduri, Leke and Bajuri.

This is the first of a series of planned release events from Samboja Lestari during 2014.

The Journey Began!

The first day started with the medical preparations.  At 4.30 in the morning, the Medical Team and Technicians were ready at Samboja Lestari Clinic and immediately departed for the Quarantine Complex.  The Medical Team was led by vet Agus Irwanto and they were all set to prepare the orangutans for their journey.  The day however, was still dark so vet Agus decided to wait for a while to avoid any unwanted mistakes during the sedation process.

The Samboja Lestari Medical Team started the sedation process at 06.06. Upi, a female orangutan who is known for her habit of making chirping vocalisations towards her least favourite babysitters was lucky number one.  The sedation dose didn’t have the desired affect so the vet decided to add to her dose.  After quite a long time, she finally fell asleep and could be moved to her transport cage.

Acul, a dominant male orangutan with growing cheekpads was the second to be sedated. Just like Upi, Acul also needed an extra dose before he finally fell asleep and could be moved to his transport cage.

The airplane which would carry the orangutans was ready and waiting for them at Sepinggan. The release truck arrived at the airport at 08.19 and soon enough, we received the signal to start loading the orangutans onto the plane, which took us only ten minutes.

Leaving the Humans’ World

The Orangutan Release Team in Muara Wahau was also up and about very early this morning. By 7 am, they were already on standby at the small airport belonging to PT. Swakarsa Sinar Sentosa.  Airport staff and the security team from PT. Swakarsa Sinar Sentosa were also ready on site.  The B3 helicopter from Hevilift arrived at the airport at around 8.30 am.  After discussing drop points with our team, the helicopter pilot decided to do a flyover of Kehje Sewen Forest to find the drop points.  He arrived back in Muara Wahau about an hour later and immediately started to refuel.  The weather was beautiful this morning, lifting the teams spirits.  We were excited to be sending our orangutans on their final journey home!

B3 helicopter arrived in Muara Wahau.

The Twin Otter airplane was sighted in the sky over Muara Wahau at 10.20 am and landed safely.  We began unloading the first four travel cages straight away and loading them into the slingload net, while the Twin Otter took off again to return to Balikpapan.  Acul, Nila, Oneng and Upi all seemed to be calm while we were loading them onto the slingload.  Vet Agnes sprinkled the travel cages with water to keep them cool and the Samboja Lestari technicians gave them their last snacks of fresh fruit.  At 10.54 am, our first four orangutans – Acul, Nila, Oneng and Upi – took to the sky, leaving the world of humans for good and finally returning to their rightful home.

Acul, Nila, Oneng and Upi were off to their forest home!

Hallo Kehje Sewen!

At 10:40 the B3 helicopter approched Drop Point 1 located on 103 Hill carrying four orangutan travel cages in the slingload net. Guided by Masino, the HLO from Samboja Lestari, the four orangutans landed safely at Drop Point 1.  Soon, Masino released the net from the sling load and gave the signal to the pilot that it was safe to fly away.

With amazing effeciency, the RHOI Team supported by Samboja Lestari technicians opened the net in order to remove the cages. Acul, Nila, Upi and Oneng were then immediately brought to a pre-designated release point on Hill 103, which is situated along the border of the Protected Forest – Gunung Batu Mesangat.

Their release points were located one kilometer away from Camp 103 and 500 meters away from the helicopter drop point.  Once her travel cage was lifted out of the safety net, Nila seemed unhappy with the Team’s presence; she slammed her cage several times while watching the Team intently.

Three Brave Females

The first travel cage to be opened was Oneng’s.  Opened by Nur, Deputy Manager of Camp 103, Oneng ran straight to a tree and climbed up.  She climbed higher and higher and did not hesitate to move from one tree to another.  Being the smallest in her group doesn’t mean she is not a confident orangutan.  She was soon exploring the area surrounding her release point until the Release Team left her to enjoy her first moments of her new life.

Oneng was the first to be released.

Masino, a technician from Samboja Lestari, who also trained as a HLO opened the second cage, Upi’s cage.  The release point was about 100 meters away from that of Oneng’s.  Once the door was opened Upi climbed a tree after stopping for a few seconds to stare at Masino and the Team.  In Samboja Lestari, Upi was known as a curious and active orangutan.  Masino who is very familiar with the female orangutan whilst in the Forest School claimed that he was so proud to see her independence.  Soon after climbing a tree, Upi disappeared in the lush forest canopy.

The third cage was Nila’s which was opened 200 meters away from Upi’s point, by vet Putra from Samboja Lestari.  Nila who was impatient stormed out of her cage.  She quickly climbed a tree and explored the area around her release point with the PRM Team following to observe her.

Acul was in the fourth travel cage and his release point was towards the Protected Forest of Gunung Batu Mesangat, 100 meters away from Nila’s.  Musa Ba Helaq, the Acting Chief of Diaq Lay Village opened his cage, representing the people of Dayak Wehea.  Once the door was opened, the male with cheekpads stepped out, but took his time before climbing a tree.

He seemed to be still under the remaining influence of sedation.  He walked slowly towards Nila’s release point and walked around a tree where Nila had earlier climbed, and sniffed Nila’s empty travel cage.  Acul looked up, but hesitation was clear in his body language.  He then decided to follow the technicians who moved Nila’s cage as if following Nila’s odour.  After about 50 meters, he sat down eating manggo leaves before finally climbing a tree.

Acul, the first moments of freedom.

Samboja Lestari: Second Group Preparation

Meanwhile at the Quarantine Complex in Samboja Lestari, the sedation preparation for the second group of orangutans started at 09.18. By 09.22, the sedation process commenced with Bajuri being the first.  After almost six minutes the sedation seemed to take no effect on Bajuri, hence Vet Agus decided to add the dose.  Bajuri was finally asleep and moved to his travel cage.

The beautiful Maduri with her fair skinned face was the next to be sedated.  Maduri seemed nervous upon seeing a technician approaching her with the sedation equipment.  She started making screeching vocalisations as if telling the technician to stay away from her. But when she saw Bajuri being moved to the transport cage, Maduri started to calm down and the technician was able to sedate her.  It took quite a while for the sedation to take effect on Maduri, but the team decided not to give her extra dose.  She was then moved to her transport cage.

After Maduri, Indo, the male orangutan who was the best graduate of Forest School was the next to be sedated.  It also took him some time to fall asleep, but just like Maduri he didn’t receive any additional medication and could finally be moved into his transport cage.

Leke, the stout dominant female orangutan was the last to be sedated.  Since it took her a very long time to fall asleep, vet Agus decided to top up her  dose.  She finally fell asleep and was moved into the transport cage which would carry her to her true home in Kehje Sewen.

By 10.21, the whole sedation and moving process for Group 2 was completed.  But before travel commenced, the Team needed to make sure that the orangutans were all awake.  It is important for their safety, to avoid serious injury which can occur if they travel while asleep; for example if the neck was badly positioned, the orangutans would be unable to breathe properly.  The journey might also cause motion sickness and regurgitation. Therefore, reversing the anesthetic is of extreme importance.

The truck arrived at Sepinggan at 11.30.  We still had to wait for around half an hour for the return of the airplane which had taken Group 1 to Muara Wahau. Upon arrival, the loading process was immediately undertaken and soon all of the orangutans were safely secured on the airplane.

Bittersweet Moment

The B3 helicopter returned to PT. Swakarsa Sinar Sentosa’s airport at 12.20 pm and refueled again, while waiting for the second group of orangutans to arrive.  This next and final group – consisting of Indo, Maduri, Leke and Bajuri – arrived on the Twin Otter at 1.41 pm. The process of unloading and loading travel cages recommenced.  Just like the first group, these four release candidates didn’t give us any trouble at all.  They quietly sat in their travel cages. Leke, especially, enjoyed being sprinkled with water by vet Agnes.

Finally at 2.00 pm, the team in Muara Wahau concluded the day by sending Indo, Maduri, Leke and Bajuri to their final destination, the Kehje Sewen Forest in the B3 helicopter slingload.  The Twin Otter also took off shortly after the helicopter took off and flew back to Balikpapan.  Tears of joy were unavoidable no matter how many times we have seen this process in the past two years.  Sending orangutans home is always such a magical moment for all of us.

The second group of the day was finally returning home.

Orangutan Release in Lembu Hill

The helicopter arrived at Drop Point 2 at 14:00 carrying Indo, Maduri, Leke, and Bajuri in their travel cages.  Guided by HLO Arief, the two males and two females landed safely.

The first cage to be opened from the second group was Bajuri’s.  Opened by Fajar a technician from Camp 103, Bajuri walked around for a while before finally climbing a Koordersiodendron pinatum tree where he started consuming young leaves.

??????????

Bowo, a technician from Camp 103 opened the second cage, which was Leke’s.  Her release point was 200 meters away from Bajuri’s.  Unlike Bajuri who took his time walking around on the ground, Leke dashed towards a tree and climbed up immediately.

Leke's cage was opened by Handoko.

Leke’s cage was opened by Bowo.

The third cage was Maduri’s. Opened 100 meters away from Leke’s by Budi Kuswara, a long term and fully dedicated driver of the BOS Foundation who has been with us for nine years.  Maduri seemed very enthusiastic to step out of her cage and quickly moved towards the trees and climbed up.

Maduri's first moments of freedom.

Indo was in the fourth travel cage and his release point was 200 meters away from Maduri’s. Once the door was opened by Bambang and Arief, Indo stepped out and watched the Team closely before climbing a tree in front of him.

Finally eight orangutans from Samboja Lestari were released into the Kehje Sewen Forest. Acul and friends now enjoy the freedom in their natural habitat after undergoing a long process of rehabilitation in Samboja Lestari.  Seeing their confidence and ability in choosing natural foods, the Team hopes that the orangutans will enjoy living and exploring their new home.

At the end of the day, the Team watched with emotion filling their hearts as the B3 Helicopter flew away leaving Camp 103 and carrying empty travel cages, bringing joyful news for the whole BOS Foundation family.  Tomorrow, Kent and Wani will join their friends in their new home.

The helicopter arrived again at the airport at 4.28 pm, bringing empty travel cages from the first group.  Meanwhile, the rest of the team in Muara Wahau could finally have a much-deserved rest while waiting for good news from the forest.  A great first day in Muara Wahau and we are hoping for another great day tomorrow!

[PRESS RELEASE] Reintroduction of 10 Orangutans From the BOS Foundation in Samboja Lestari

In the spirit of World Forestry Day on March 21, 2014, the Borneo Orangutan Survival Foundation releases 10 orangutans from the East Kalimantan Orangutan Reintroduction Center in Samboja Lestari back into their natural habitat.

  

Samboja Lestari, East Kalimantan, March 20, 2014. Following the successful reintroduction of 12 orangutans from the East Kalimantan Orangutan Reintroduction Center at Samboja Lestari together with 3 cross-province reintroductions in 2013, the BOS Foundation continues their reintroduction program in East Kalimantan in 2014 with the release of 10 rehabilitant orangutans from Samboja Lestari to the Kehje Sewen Forest, East Kalimantan.

Six female and four male orangutans depart from Samboja Lestari towards the release site in the Kehje Sewen Forest in East Kutai and Kutai Kartanegara regencies on March 20 -21, 2014.  Eight orangutans, divided into two flight groups, depart on March 20 from Sepinggan Airport, Balikpapan, East Kalimantan towards PT. Swakarsa Sinar Sentosa Airport in Muara Wahau Regency. Thereafter, they are flown by helicopter slingload to the Kehje Sewen Forest. Another two orangutans fly the next day on March 21 using the same route and transport system.

The Kehje Sewen Forest is an Ecosystem Restoration Concession (ERC) managed by PT Restorasi Habitat Orangutan Indonesia (RHOI), a company that was established by the BOS Foundation on April 21, 2009, solely to acquire the rights to use and manage a forest which is desperately needed to release rehabilitated orangutans from the BOS Foundation Orangutan Reintroduction Center at Samboja Lestari.

The orangutan release event involves the collaboration between the BOS Foundation and all stakeholders, including East Kalimantan Provincial Government, East Kutai and Kutai Kartanegara Regency Governments, East Kalimantan Conservation and Natural Resources Authority, and the people of East Kutai and Kutai Kartanegara. The BOS Foundation would also like to convey their gratitude for the moral, financial and logistical support from partner organizations such as BOS Switzerland and Orangutan Protection Foundation UK, private sectors such as First State Indoequity Peka Fund managed by First State Investment Indonesia and exclusively distributed by Citibank, Salim Ivomas, and BCA Bank, as well as individual donors and other conservation organizations across the globe who are concerned with orangutan conservation in Indonesia.

The Head of East Kalimantan Conservation and Natural Resources Authority, Ir. Y. Hendradi Kusdiharjo, M.M. said, “We are delighted to see the continuity of this orangutan release program. It is very important for us to ensure their survival in the place where they belong in natural forest. We also have to remember that a thriving forest can be indicated by the well-being of the animals in it, especially the orangutans.”

Successful orangutan reintroduction programs need to continue in order to return displaced orangutans back to natural habitat and achieve the target stated in the 2007-2017 Indonesian Orangutan Conservation Strategy and Action Plan. The Action Plan was launched by the President of the Republic of Indonesia during the Climate Change Conference in Bali, 2007. It states that all eligible orangutans in rehabilitation centers should be released by 2015, and this has been validated by all levels of government, including the provincial and regency levels.

The CEO of the BOS Foundation, Dr. Ir. Jamartin Sihite stated, “We will continue our efforts to meet the target stated in the 2007-2017 Indonesian Orangutan Conservation Strategy and Action Plan. The cooperation between the Government, private sectors, and donors plays an important role in this event. I hope in the future more support can be given from all concerned parties. Let’s realise that this is the duty of us together.”

Drh. Agus Irwanto, Program Manager of Samboja Lestari also stated, “We start 2014 by releasing 10 orangutans. We are optimistic that we will release more orangutans into their natural habitat in the future. However, this has to be supported by the availability of suitable and safe forest. We sincerely hope the concerned parties continue their support, both in the execution of the reintroduction and the provision of suitable and safe forest in the future.”

Deforestation in Indonesia is moving rapidly. Without serious efforts to conserve the forest, orangutan conservation efforts will be futile.  In return, the target stated in the 2007-2017 Indonesian Orangutan Conservation Strategy and Action Plan cannot be achieved. In the spirit of World Forestry Day, the BOS Foundation would like to reach out to all the concerned parties to achieve this target, including to realise the conservation of forest and the animals within.

ABOUT BOS FOUNDATION

Borneo Orangutan Survival Foundation (BOSF) is an Indonesian non-profit organization based in Bogor, West Java, Indonesia, which is committed to rescue, rehabilitate, and reintroduce Borneo orangutans to their natural habitat, as well as educating local communities and increasing public awareness about the conservation of orangutans.

Established since 1991, BOSF has partnered closely with the Ministry of Forestry of the Republic of Indonesia and are supported by international donors, as well as other organizations. BOSF is currently headed by Prof. Dr. Bungaran Saragih as Chairman of the Board of Trustees. For more information, visit www.orangutan.or.id.

About PT. RHOI

PT Restorasi Habitat Orangutan Indonesia (RHOI) is a company that was established by the BOS Foundation on April 21, 2009, solely to acquirethe Utilization of Forest Timber Products through Restoration of the Ecosystem (IUPHHK-RE), also known as an Ecosystem Restoration Concession (ERC). As a non-profit organization the BOS Foundation is not allowed to apply for this license due to government regulations. Hence, RHOI was established.

On August 18, 2010, RHOI was issued an ERC permit, giving them the authority to use and manage 86,450 hectares of rainforest and provide a sustainable and secure habitat for orangutans for at least 60 years, with the option of extending for another 35 years. Issued by the Ministry of Forestry, this ERC license cost around US$1.4 million, which was funded by generous donations from donors and the BOS Foundation’s partner organizations in Europe, Australia and the USA.

RHOI named this forest Kehje Sewen, which translates as ‘orangutan’ in the local Dayak Wehea dialect. By name and nature, the Kehje Sewen Forest became a forest for orangutans. For more information, visit http://www.theforestforever.com.

Samboja Lestari Release Candidate Profiles

In the near future, 10 more orangutans will be living in Kehje Sewen forest. They are from Orangutan Reintroduction Center at Samboja Lestari who will be reintroduced into the forest on March, 20 and 21 2014. Here are their profiles. 

GROUP 1

1. ACUL

IMG_6324_acul_edited_1

Acul arrived in Samboja Lestari from Bontang on June 25, 2001 when he was only four years old.

Due to his semi-wild nature, Acul’s skills grew rapidly in Forest School. He is intelligent in choosing natural foods, building nests and spends most of his time in the trees. Acul is now a dominant male orangutans with growing cheekpads. Despite his dominance, Acul is never aggressive towards his friends.

Acul is now 17 years old and weighs 62 kg.  Soon the handsome Acul will enjoy true freedom in the Kehje Sewen Forest.

2. NILA

IMG_6509_nila_edited_1

Nila arrived in Samboja Lestari from Bontang on April 22, 1998 when she was still four years old and weighed only 4 kg. This female was cared for in our socialization enclosure together with Titin, Juminten, and Sarmi who were released in Kehje Sewen last year.

Nila was moved to Island 6 and improved her natural skills to survive in the wild whilst on the island. One of her friends on the island is Oneng, who is also a candidate for this release.

Nila prefers to spend her time alone and dislikes human presence. She is also skillful in choosing natural foods and she prefers to find her own food rather than eat the fruit provided daily by technicians. Her favourite food are leaves.

Nila is now 20 years old and weighs 68 kg. The adult female who is active in the trees soon will explore the lush forest of Kehje Sewen, her true home.

3. UPI

Upi was handed over to Samboja Lestari on July 4, 2001 by a resident of Balikpapan who had been keeping her as a pet. She was five years old and weighed 16 kilograms.

Before being prepared as a release candidate, Upi learned in Forest School and then was promoted to Halfway House in 2004. She is skillful in recognising her natural foods. Her memorable habit as recalled by the babysitters is making a chirping sound towards the babysitters she disliked.

Upi is now 18 years old and weighs 44 kilograms. Soon the beautiful female orangutan will enjoy the beautiful free life in her new home in Kehje Sewen Forest.

4. ONENG

IMG_6594_oneng_edited_1

Oneng who was only three years old arrived in Samboja Lestari on April 5, 2006 after being confiscated by the Conservation and Natural Resources Authority in Tenggarong from a resident of Muara Wahau who had been keeping her as a pet. Oneng was placed on Island 6 with other orangutans.

Oneng improved her survival skills on Island 6 with Nila, who will also be released with her, and Sarmi who has previously been released in Kehje Sewen in October 2013.

Oneng who is now 11 years old and weighs 41 kg is the youngest orangutan in this release group. Despite her young age, Oneng is famous for being smart and skillful in escaping from the island by paddling in the water. There is no doubt in her ability in recognising natural foods and building nests. The female orangutan of East Kalimantan will soon enjoy her true home in Kehje Sewen.

GROUP 2

1. INDO

IMG_7752_indo_edited_1

Indo was illegally kept as a pet by a resident of Samarinda before finally handed over to Samboja Lestari on April 10, 2001. The young male orangutan was only five years old and weighed 11.5 kg.

He was the best graduate from Forest School in his time and moved to Halfway House in 2004 to 2005 to improve his skills before being prepared as release candidate.

Indo who is skillful in recognising natural foods is a dominant but calm orangutan. Now 18 years old and weighing 60 kg, Indo is ready to put his skills into practice in his natural habitat.

2. MADURI

IMG_6343_maduri_edited_1

Maduri arrived in Samboja Lestari on Desember 16, 1998 after being a pet of a resident in Muara Wahau, Kutai Timur Regency. She was two years old and weighed three kilograms.

Having graduated from the Forest School, she was moved to the Halfway House to undergo the last phase of her rehabilitation process between 2003 to 2007. Maduri who is skilled in recognising natural foods and spends most of her time in the trees was then prepared as a release candidate.

This beautiful orangutan with a fair face is now 18 years old and weighs 43 kg. Maduri has transformed into an adult female orangutan who is ready to go back to her true home in Kehje Sewen Forest.

3. LEKE

IMG_6394_leke_edited_1

Leke was illegally kept by a resident of Balikpapan before being handed over to Samboja Lestari on April 23, 2001. The female orangutan was only three years old and weighed 5.5 kg. She was suffering from dehydration, acute diarrhoea, and malnutrition, hence immediately placed her under intensive care with the Medical Team.

Leke learned in Forest School in 2001 until 2005 and earned the title of a smart student, who was eventually promoted to the Halfway House to be prepared as a release candidate in 2008.

The strong and large orangutan is a dominant female who doesn’t submit to her male counterparts in rivalry over food. Now 16 years old and weighing 51 kg, brave Leke is ready for her new life in the real forest.

4. BAJURI

IMG_6709_bajuri_edited_1

Bajuri was handed over to Samboja Lestari by Mulawarman University Botanical Garden in Samarinda on March 1, 2006. He was 6 years old.

In the Forest School, Bajuri was very active and independent. He was skilled in recognising natural foods and building nests. Because of his skills and ability, Bajuri was then prepared as one of our release candidates.

Despite being dominant, he is not aggressive towards his friends. Bajuri is now 14 years old and weighs 49 kg. Soon he will prove his independence and survival ability in the forest of Kehje Sewen.

GROUP 3

1. KENT

IMG_6658_kent_edited_1

Kent arrived from Sangkulirang in Samboja Lestari on March 25, 1999. He was just a baby, aged two months old weighing five kilograms, and was rescued from a local person’s farm. Apart from arriving without his mother, the baby was suffering from dehydration and acute diarrhoea due to a worm infection. Kent graduated from the Samboja Lestari Forest School in 2004 and was placed in Halfway House to be prepared as a release candidate.

The independent Kent is skilled in surviving in the wild and he also dislikes human presence around him. He is now 16 years old and weighs 45 kg. Soon he will live as a true wild orangutan in Kehje Sewen Forest.

2. WANI

Wani is now 17 years old and weighs 34 kilograms. The beautiful orangutan will soon go to her true home in Kehje Sewen Forest.

Stories from Mona, Agus and Casey

Mona Encounters a Snake

Text by: Agus, PRM Technician

The monitoring team left Camp 103 at 04.35 and thick fog still covered the Kehje Sewen forest.  At 05.20, we reached Mona’s night nest, but she was still fast asleep.  Waking up at 06.19, she sat up in her nest, yawned several times and rubbed her hands for a while.  Pretty much just like we humans do on a working day.  A minute later, Mona climbed out of her nest and sat on a fallen Macaranga pearsonii tree.  She sat there looking relaxed and gazing at the Telen River to the north.  After a while, she spotted the team and climbed down the tree making movements towards us.  Mona stopped after seeing us withdraw.

Mona_kecil_Agus (3)

????????

Despite her great adaptation to her new environment, Mona’s curiousity still sometimes gets the better of her.  Therefore, we always make sure to keep our distance.

At 08.10, Mona started moving towards the foot of the nearby hills and eating Lhitocarpus gracilis (Fagaceae).  Seemingly having eaten her fill, she started jabbing a rock into a Shorea parvifolia root as if she was harvesting some sort of food item.  Seeing that she didn’t eat anything in the end, she was probably just curious.

Done with abusing the unfortunate rock and root, Mona approached us again.  But after only a few steps, she ran in the opposite direction and hastily climbed up a tree, hanging on and looking afraid.  Apparently she saw a snake near us and ran away to save herself.

IMG-20140218-WA0073 ULAR -by Franky

The snake that Mona saw.

Mona made a nest at 10.09 to rest for a bit, and all the while we were still observing from a safe distance.  It wasn’t long before she got up again and started foraging once more.  This time, she found she focused her feeding efforts on cambium.

At 16.00, the rain started to fall.  Mona who was now eating Macaranga pearsonii ran quickly to the nest she made earlier.  She made a few little adjusments to it and lay down.  Since the rain was getting harder we decided to go back to Camp 103, but not before we made sure there was no more movement from Mona’s nest.

Agus, We Meet Again!

Text by: Fajar, PRM Technician

We departed from Camp 103 for Gunung Belah, filled with confidence that we would immediately find the orangutans we were searching for.  We started to track orangutans using the radio receiver, however by 13.00, we still hadn’t located a single orangutan.   After a short break, we finally picked up Agus’s signal which we followed only to find him not very happy with our presence.  He kiss squeaked and threw branches down towards us.

Agus_Agus_1

Agus_kecil_Awal (4)

After two hours of direct observations, Agus suddenly decided to quickly depart and he  moved down the hill rapidly.  The Team tried to follow him, but through the trees and thick rattan, it was impossible to keep sight of him.  We lost him at 15.47 and were unable to pick up his signal again.  All searches were in vain.  During previous monitoring observations, we have recorded that Agus has a wide and varied diet.  He has been recorded consuming fruit, tree bark, wood, leaves, ants etc.  He also does spends most of his time in tall trees most of the time.  Agus is one of the best orangutans under our observations and we are confident that we will observe him again soon.

Accidentally Met Casey

Text by: Arif, PRM Technician

Our plan for the day was to observe Siwi, but instead we met Casey at the “broken car” area.  Casey looked healthy and was going about her business as usual.  She spent time eating and traveling through the trees.  She also chased us away several times and in the end the Monitoring Team, consisting of Arif, Bowo, Holit, and Handoko ran for safety and observed her from a distance.

Updates from the Forest!

Siwie was Found in the Berlian Hill

by: Arif and Bani, PRM Technician.

At 7 am, the team started their daily patrol to locate Siwie.  They made their way to an area of Kehje Sewen Forest called Kali Tengah . This time, the team divided into two teams. Arif and Vio were in the first team while Guswan and Kholid formed the second team.  Unfortunately, when they reached the area, they couldn’t locate Siwie. Not even her used nest or food traces were seen. They searched hard to find any clue as to which direction Siwie has traveled.

Information received from the team that had conducted the previous daily patrol was that they had found a new nest in the Berlian Hill area. Chances were, Siwie or Inge were there, so the team decided to go to Berlian Hill to find the answer.

As soon as they got there at 12.30 pm, one of the team heard the sound of branches being broken. The team walked faster to find out who was there.  But before they had a chance to identify the orangutan, the orangutan had already dashed off quickly. Not long after, there was one more orangutan arrived into the area. The team smiled in relief because it was Siwie!  Without a moments hesitation, they started to observe her for two hours straight.

Siwie

Siwie.

Siwie seemed uncomfortable with our teams presence. She kisssqueaked at the team to show her displeasure and even approached the them in an attempt to drive them away. The team backed off quickly before Siwie could catch up with them. After that, they decided to observe her from a respectful distance. Siwie was seen roaming around the area and at last, the team lost her as she moved quickly up a steep slope. The impassable terrain halted their new search for Siwie.

Back from the days’ patrolling, the team ate their dinner together at Camp 103. When they finished their meal, Nur and Bani asked all of the technicians to gather for their usual weekly meeting in which they shared information that each individual team had gathered during the days’ patrolling efforts.  It really is important that the team discusses in detail their results so that the teams on duty the next morning, know where to start their searches and which orangutan to search for and gather data on.

Weekly meeting.

Noel and the Duo Mum-Daughter, Yayang-Sayang

by: Bani, PRM Technician.

The next morning, the monitoring team again conducted a daily patrol in the Berlian Hill area.  Despite intensive efforts to locate orangutans in the area, they were unsuccessful in seeing a single orangutan. Nevertheless, the team continued their search and finally were rewarded by locating Yayang, Sayang and Noel. They were able to take Noel’s photo, keeping an eye on him to ensure he didn’t follow them and approach Camp 103. They also had a chance to observe Yayang and her daughter, Sayang for two hours which was super.

Noel.

YS

Yayang and Sayang.

Yayang and Sayang are independent and act like true wild orangutan should. They play high up in the trees all the time. Little Sayang is very active. Now that she is growing bigger, she plays on her own; she is no longer a baby who is always in her mum’s arms. She also likes to try natural foods found in the forest. The team noted that Sayang had tried several foods including fruits, flowers, leaves, ants, lianas and cambium bark. While Sayang explored her surrounding, her mother, Yayang would stay in one tree, watching her daughter playing. When Sayang moved further away, Yayang would follow her wherever she moved.

The lovely Sayang.

Inge and Casey, the Best Friend Forever!

by: Bani, PRM Technician.

These two lovely ladies, Inge and Casey have grown even closer to each other. They are such good friends now! They had met and spent time together several times and even their nests were found built side by side.

Inge_Casey_2

Inge and Casey, BFF!

The team observed Inge from 6.08 am from when she first awoke and emerged from her nest. She then started consuming Macaranga personii, her favourite food for her breakfast.

Inge_Casey

Inge and Casey like to play together. Sometimes they descend to the ground, but most of the time they play up in the trees. That day, the team noted that Inge visited 20 kinds of trees before finally building her night nest and settling down  to sleep at 5.40 pm.

Friendship in Kehje Sewen

There is a shy orangutan who is now friends with a new ‘resident’ who just arrived in the Kehje Sewen forest. Meanwhile, there are two best friends who were released together, and they sometimes appear content, but at other times they fight over small things.  Life in Kehje Sewen has become more colorful than ever…

New Friend for Casey

The beautiful Casey who was our vey first orangutan to be released into Kehje Sewen in April 2012, is now friends with Lesan and Hamzah who were also released in early 2012, and they sometimes meet and spend time together in the Gunung Belah area.  Casey who was very shy, has now become more open and ready to mingle with orangutans – even with orangutans who just recently arrived in the  Kehje Sewen forest.  The monitoring team have reportedly seen Casey playing together with Noel, several times which is very interesting news.

Casey

Casey

 

Since he was released into the forest, Noel separated from his good friends Inge and Siwie.  From then on, Noel appeared to be somewhat lonely and at a loose end and he was observed roaming around the dirt track towards Camp 103.  We don’t have any idea where or when Casey and Noel met, but they have been seen together on the hill near Camp 103. Casey was happily sitting in a tree while feeding on Ficus bark and playing with Noel who looked equally content!

Noel.

Noel.

Noel is a very kind male orangutan who is always gentle towards female orangutans, including Casey.  When he was still together with Inge, he protected her wherever she was. It seems to be the same with Casey.  We are very glad to hear Casey has a new friend, at least for now.

Juminten

Juminten was finally seen around the Lembu river after two months of not being able to pick up her signal.  Juminten has grown into an independent adult female orangutan and she doens’t like to be near to people. When she saw the monitoring team approach her, she stopped eating and looked very disturbed by the team’s presence. She kiss-squaked and tried to drive the team away. The team retreated back towards the main road, leaving her alone.

Juminten.

Juminten.

Knowing that Juminten doesn’t like to be close to people, the team observed her carefully. The next time the team observed her, Juminten was feeding for a long while then started to build her night nest.  Once she had settled down to sleep the team returned home, very happy to see that Juminten was doing so well in the forest.

Mona and the ‘stolen’ Nest!

Mona on the other hand doesn’t seem to be quite as good at making nests as Juminten and she appears to still be learning how to make a sturdy and comfy nest in which to rest.

Emerson.

Emerson.

One day, maybe she was just too lazy to make a new nest or thought Emerson wouldn’t mind and  she decided to sleep in Emerson’s old nest.  At that point, Sarmi was on the scene and her and Mona had a bit of an argument. Emerson who was busy making a new nest saw and quickly drove Mona away to protect Sarmi who he spends more time with.  Because of his big body size, Emerson couldn’t move as fast as Mona.  Mona ran back to Emerson’s newly built nest and hid in it. Emerson was really not impressed by this, but he decided to make a new nest anyway.  In the days which followed, Mona has repeatedly come back to the same nest. The nest that Emerson built.

Mona.

Mona.

Although Mona is still learning to build a nest, she has already settled into her new home in other ways. The monitoring team observed that Mona is eating several wild foods around and has been particularly focusing on consuming the young leaves of Etlingera and Baccaurea tetranda.  We’ll keep an eye on Mona and hope that next time we write we can report on new skills she has developed.

New Year, New Blessings

 The Post Release Monitoring (PRM) Team in Kehje Sewen has faced a huge challenge since the radio telemetry receivers suddenly stopped working last October. New equipment has been ordered and we are eagerly awaiting its arrival. But in the interim the team must monitor orangutans manually; that means using all of their skills and knowledge related to orangutan range behavior.  Instead of relying on technology, they must rely on all their experience to search for orangutan signs such as broken branches, opened canopy, reasonably new nests, traces of urine or feces, and food leftovers, and ultimately pinpoint their locality.  Finding orangutans that have been well schooled to be wild is understandably hard.  It was almost mission impossible.

Inge in particular – our 100th orangutan – seemed to have changed location and had not been seen since the second day of her release.  She quickly disappeared into the forest, leaving no trace for the technicians to follow.  Siwie was the same.  The newest residents of Kehje Sewen, Yayang and her daughter Sayang, were also nowhere to be found. Fortunately, the team spirit remains high. “When we work together as a team and we don’t lose hope, we can do it,” they said.

And they did it! Not only did they find Inge, Siwie, Yayang and Sayang, there is apparently love growing in the forest between Noel (released back in October) and Diah (also a new resident, released together with Yayang and Sayang in December). The following short stories are from our technicians in Kehje Sewen that we have loosely translated.

*****************

Yayang & Sayang Return

Text by: Agus and Awal

Two of our very first cross-province releases, Yayang and Sayang, had not been seen since the third or fourth day of their release. The mother-daughter pair seemed to be exploring the forest far beyond the reach of our team.  But on December 28, 2013, they returned!  We spotted them playing in the trees right in front of our camp.

A couple of technicians, who were on their day off quickly geared up and followed them. The pair weren’t too happy seeing the team, kiss-squeaking and throwing branches at them.  Obviously, they didn’t return to meet us.  Keeping a safe distance from them, we continued to follow them while keeping a low profile to let them know that we were not a threat.  We simply wanted to make sure that they were okay. They finally seemed to relax. That day they made a nest at around 5.30 pm in a mahang tree (Macaranga pearsonii).

Because we had very little data on Yayang and Sayang, we decided to do nest-to-nest monitoring for the following six days.  Unfortunately, on the first day of the nest-to-nest follow, we lost them again at around 3 pm. Sayang was startled by something and fearfully fled, followed by her mum.  They moved so quickly it was impossible to keep up and hence we lost track of them.  But on the first day of the New Year, they were spotted again in front of our camp.  This time the whole camp saw them.  Three of us hurried to follow them, determined not to lose them again.  It was late afternoon and soon enough Yayang and Sayang made their nest, only 400 meters from camp.

Nest-to-nest activities resumed the following day.  Leaving camp at 5 am every morning, we waited for them to wake up and followed them all day through the forest.  Sayang usually woke up first and started swinging around the nest, probably to wake her mother up. Mum, on the other hand, took her time.  We could only see her arms stretching lazily, before she finally got out of the nest.  Thirty minutes later, she approached Sayang, sat with her on a branch, and started to nurse her young.  It was a heartwarming sight.

Yayang and Sayang Return! (photo by: Agus)

Yayang and Sayang look healthy and have adjusted wonderfully to life in their true forest home.  They eat a variety of forest foods, such as mahang fruits, the cambium of lianas, young leaves of mahogany (Aglaia sp.), and fruits of bayur tree (Pterospermum sp.), gambier tree (Uncaria glabra), as well as jackfruits (Artocarpus sp.).  They play high up in the canopy like wild orangutans and rarely come down to the ground, except once when we saw them drinking water from a spring.  They are also never too happy seeing humans getting too close for comfort.

Also, we found out that Yayang has not forgotten her friend, Diah.  These two East Kalimantan orangutans (Pongo pygmaeus morio) grew up together in Nyaru Menteng, Central Kalimantan, went to forest school together, and spent time on a pre-release island together.  The friendship is apparent as Diah often pays a visit.  Yayang welcomes her friend warmly and they are often seen playing and feeding together.

Nest-to-nest activities of Yayang and Sayang have concluded successfully.  We will repeat nest-to-nest follows in two months, but for now, we wish them well and hope that they don’t travel too far, at least until the new radio telemetry receivers arrive.

*****************

Diah & Noel: Love is in the Air

Text by: Agus

On January 7, 2014, while we were monitoring Yayang and Sayang, Diah came over to spend some time with Yayang.  For a while, they were feeding in a tree, feasting on an abundance of fruit.  Suddenly, Noel showed up and it was clear that he was looking for Diah. Diah, too, seemed happy to see him.

Love was in the air and the pair were recorded mating.

This was the second time we witnessed these two hit it off.  But the first time they were more discreet and it happened so quickly we didn’t have time to record the event.  This behavior is very encouraging as it is the sole reason why we reintroduced them into the forest; to establish a new viable orangutan population of truly wild orangutans.  We are crossing our fingers for Diah and Noel.  We hope love stays in the air and a little Noel or little Diah will soon arrive.

Inge & Siwie: The Rulers of Kali Tengah

Text by: Fajar, Frangki and Arif

Inge and Siwie were both released in the Gunung Belah area, around 1.5 kilometers from camp. But days and days of searching on Gunung Belah did not provide us any clues as to where they had gone.  On January 10, 2014, however, we remembered that Asep – our maintenance man – recently reported two orangutans crossing in front of him while he was fixing a part of the road damaged by a landslide.  This location is quite far from camp in an area locally called Kali Tengah, which literally means the Middle River because it is located roughly halfway between Pelangsiran (the nearest community to our camp) and Camp 103, or around 9-10 kilometers from camp.

We decided to search the area and follow up on this information.  After we passed the landslide, we rested on the roadside.  Our rest only lasted a few seconds as Arif saw an orangutan foraging in the trees on a nearby hill.  Instantly, Fajar got up and ran towards the hill with Arif and Frangki following not far behind.  We had to go around a steep cliff to get there and had to watch our step and keep an eye on the orangutan at the same time. But it all paid off and once we got there, we found little Miss Clean, Inge – the 100th orangutan released by the BOS Foundation – feeding on the fruits of a matico (Piper aduncum) tree.

Inge, our 100th orangutan, now lives in Kali Tengah area. (photo by: Arif)

Startled by our arrival, Inge stopped eating for a minute or two, as if ensuring that we were not there to bother her.  Then she continued eating.  A few minutes later, we saw movements to the west, not far from where Inge was.  It was Siwie!

We immediately split up. Two of us followed Inge and the other followed Siwie. In the end, we all met up again because Inge and Siwie decided to join together; they were obviously close friends.  They played together and at least for now, seem to be using the same home range.  At the end of the day, they even made nests in the same tree.

Siwie is never too far from Inge. (photo by: Arif)

Since then, we have conducted nest-to-nest monitoring on Inge and Siwie. By the time this story was written, we had been following them for three days.  Both looked healthy and were feeding well, mostly matico fruits that were found in abundance in that area. For now, Inge and Siwie seem to have found a piece of the forest they call home. They never traveled too far from Kali Tengah.  We call them the Rulers of Kali Tengah.

Searching for Leo & Titin

Text by: Fajar

Not all of our searches were successful. Leo and Titin, too, have not been seen for a while and we are anxious to see whether their romance last year continues. But in addition to not having the radio telemetry receivers, searching for these two poses another challenge; the raging Lembu River.  Lembu is a big river with fast currents and rapids that often floods.  And sure enough, it flooded again on the morning of December 29, 2013 after an overnight rain.

But we didn’t give up. We crossed the river using the sling that we used to transport Leo, Titin and Juminten across the river to their release site.  Then we patrolled the area from the release site up to the foot of a big hill far in the north.  Late in the afternoon, we found two old nests; both located close to each other in two neighboring trees. Moving forward, we found two more nests – newer, possibly around 1-2 days old – also close to each other.  One was a huge nest, fit for a big adult male of Leo’s size.  The other was smaller.

All of the sudden, we heard a long call followed by two more. The sound was far from the forested hill. We debated whether it was Emerson’s long call. But Emerson was released on the other side of Lembu River, far from Leo as to avoid competition. And the sound of the raging river was too loud. It was impossible that we could hear Emerson’s long call all the way from here. So whose long call was it?  Was it Leo?  Whose nests were they?  Were they Leo’s and Titin’s?  Are they still together?

We only found several nests. (photo by: Fajar)

We could not provide the answer. It was late and we couldn’t risk crossing the Lembu River in the dark.  Since then, we have not been able to continue our search because the rainy season is officially here. It rains almost non-stop every day and the Lembu River is too dangerous to cross, even by sling.  We can only hope that it really was Leo that we heard and that he still travels together with Titin.  We will let you know once it is safe to cross the river and hopefully we will have the technology (radio telemetry) on our side by then.

*****************

Here at the Headquarters in Bogor, we are proud of our PRM team in Kehje Sewen.  They have proven their monitoring skills, even without the latest technology.  Although there are still many orangutans that they need to search for, they have managed to find some of the orangutans we have not seen for a while and witnessed the promising romance between Diah and Noel.  The beginning of 2014 seems to be bringing new blessings.  We hope the blessings continue as well as your support for the orangutans, for more releases and to support our amazing PRM team.

Meet the Big Guy, Emerson!

Remember the big guy, Emerson?  We bet you do!  He is the one with large cheek-pads and loud long-calls who has been living in the Kehje Sewen forest for almost 3 months now.  Over the last two weeks we conducted our routine daily monitoring activities as usual.  However this time we intended to monitor Emerson manually since our radio transmitters are broken; the elements in the forest are not always kind to electronics!  But new orders have already been placed and we are patiently waiting for our new equipment to arrive  (both for Kehje Sewen and Batikap camp). In the meantime, the monitoring activity is still going on manually in Kehje Sewen which is possible (albeit a little more time consuming) and indeed what earlier reintroduction programs did!

Good looking Emerson!

Good looking Emerson!

The Post-Release Monitoring (PRM) team started monitoring from 8 in the morning. They first walked towards Emerson’s release point although when they arrived there, they didn’t see Emerson. There was no used nest or food traces in the area.  The team kept on looking and walking around the area until midday, but still no sign of him.  The team then decided to take a short rest and have a drink and that was the time when they heard a loud long-call from south-west area.  They quickly moved towards the direction of the sound and gladly found that Emerson was up in the tree posing like a king!

Emerson looked disturbed by the team’s presence.  He kiss-squeaked and threw some small branches down towards the team.  After he calmed down, he started to eat the young leaves from a nearby liana, while continuing to sit in the Lithocarpus tree.

IMG-20131216-WA0012

Presumably satisfied with the food he had eaten, Emerson started to build his nest for a nap.  He broke some Lithocarpus branches to make his nest which was good and sturdy – nest construction qualities very much needed to fit his big body.

Around 3 pm, the team left Emerson after confirming the big guy appeared to have already fallen asleep, enjoying his siesta.  Until we meet again, Emerson!

Not to forget, Happy New Year from the forest!

Sayang who is very agile and active.

Yayang has a very agile and active little daughter named Sayang. On their release day, and as soon as their travel cage was opened, Sayang dashed out of the travel cage and ran directly to the nearby tree.
Yayang is clearly a very caring, sensible mother and as such is not too keen on seeing Yayang play too far away from her. Attempting to keep her close by, sometimes Yayang grabbed her daughter’s hand to make sure that she was not traveling too far. But Yayang’s desire to explore her new environment was very high, so her Mum patiently followed Sayang wherever she went.

Sayang likes to swing between trees. She uses both her hands and legs to move from one tree to another with Yayang continuously following and grabbing her daughter’s hand while moving. After playing and swinging for a while, the Mum and daughter pair took a rest. They both sat relaxing on the branch a tree. While resting, Yayang nursed her daughter for approximately five minutes. After that, they started to search for food. Yayang and Sayang were very smart in choosing their natural foods despite the fact that it was only their first day in their new environment, and they consumed a range of foods including young rattan leaves (Calamus Sp.), Jackfruit (Artocarpus Sp.), Baccaurea sp., Polyathia sumatrana, cambium bark and young Ficus leaves. Obviously their years on the pre-release islands at Nyaru Menteng have given these two orangutans the best possible forest training we could hope for.

Finally, at 6.04 pm, Yayang built her nest in a Baccaurea sp. tree. Her nest looked very firm and strong enough for the two of them. Before bed, Yayang handfed her daughter the fruit of Artocarpus sp. At exactly 6.17 pm, they both lay down in their nest. The team had to make sure that they were comfortable in their first nest in Kehje Sewen before they left them and went back to Camp 103 at 6.25 pm. Goodnight Yayang and Sayang. Enjoy your first night in the Kehje Sewen forest!

Diah Likes to Eat!
Soon after being released, Diah climbed a tall tree nearby. This beautiful orangutan then consumed a species of liana, Artocarpus sp., Artocarpus tamarin and Lithocarpus on her first day in the forest. Diah is naturally a very active orangutan. She likes to move between trees, showing off her agility.

On her first day, she ate and ate and ate as much as she could! Having eaten her fill, she then started to build her very first nest in the Kehje Sewen at 5.15 pm. Her nest looked really comfy and sturdy constructed on a Lithocarpus tree.

She kiss-squeaked at the team, while still busy building her nest. It sounded like a warning for the team to immediately leave her alone because she wanted to sleep. No further movements could be seen in the nest at 5.45 pm, meaning Diah had probably already fallen asleep – exhausted from her long journey. The team then decided to leave Diah for a good nights sleep and went back to Camp 103.

It was really a great day! Three orangutans have returned back to the forest, the home where they belong, they have already found their favourite foods and they also succesfully built their first nests in the Kehje Sewen forest. More adventures to come! Enjoy your new home girls!
