How to Get to Tanjung Puting National Park

To reach Tanjung Puting National Park you will need to fly to the airport of
Pangkalan Bun, Kalimantan. Pangkalan Bun =PKB

The easiest option is to fly to Soekarno Hatta International Airport in Jakarta (Java). All
travel agents outside of Indonesia should be able to arrange this. On arrival at Jakarta
airport you have several options, depending on your time and budget.

1. Fly from Jakarta to Semarang And Pangkalan Bun
Journey time approx. 1 hr. One way cost approx. Rp.1.900,000 with Garuda or US$ 230

There are 12 flights daily between Jakarta and Semarang. The last flight departs at
6.00pm. You will probably have to stay overnight in Semarang and then catch a flight to
PKN the next day. There is one early morning flight from Jakarta that connects with the
plane to PKN, but this is risky because you might be delayed and miss the connection.
From Semarang you can take a flight to PKN with either INDONESIA AIR TRANSPORT or TRIGANA AIR next morning (one way cost approx. Rp. 955,000. Remember these flights have a 10 kg baggage limit. ORANGUTAN EXPLORE can arrange all your flight with 10 % charge from total flight rates.

Flight Schedules
Semarang (Java) to Pangkalan Bun (Borneo)
– INDONESIA AIR TRANSPORT (13.10 – 14.35) Every Day

2. Take a train from Jakarta Gambir railway station to Semarang
(Journey time approx. 5 ½ hrs – 9 hrs / cost Rp. 80,000 standard class to Rp.270,000 executive class. There are several trains daily).
First take the Damri (public) bus from the airport to Gambir station (Rp. 20,000). From there, take a bajaj (motorised rickshaw; Rp. 15,000) to Stasiun Senen and book your train
ticket. You will need to book your ticket at least 2 hrs in advance. You can either take a long, scenic route by day and arrive at Semarang in the evening and stay there, or take an overnight train from Jakarta to arrive in Semarang early the next morning. There may
be fast trains leaving late afternoon, whereby you could overnight in Semarang before catching a flight to PKN the next morning, but you will need to check this when you arrive in Jakarta.

3. Boat
It is possible to take a ferry from Semarang (Java) to the port of Kumai (on Borneo, a couple of kms from Pangkalan Bun). This is a cheap but very slow and less frequent option. The Pelni ferry is government run and popular with local people. Tickets can be bought at the local Pelni office in Semarang; avoid agencies with commission. Non-Pelni ferries are also recommended, as they are often cheaper, cleaner and faster. Generally,
the journey takes approximately 19 hours (cost approx. Rp 300,000). The boat schedule is available in Yogyakarta, Solo, Semarang and Jakarta about 2 weeks in advance so you will have to find out the boat times and book the tickets yourself on arrival. As a rule, boats tend to depart every 2/3 days. On arrival in Kumai, you can then arrange to take a local minibus (Rp 15,000) or private taxi (Rp. 90,000) to PKB. (½ hr). You will be able to find more information on www.pelni.com .

4. Fly from Jakarta to Pontianak (West Kalimantan) and then on to PKN.
(cost Rp 1.496,000 on Kalstar (Mon-Sat) These flights are cheaper but you will have to stay overnight in Pontianak before flying south to Pangkalan Bun, since the small plane to PKB leaves very early in the morning.

Fly from Jakarta to PKN via Palangkaraya (Rp.990,000 on Sriwijaya Air (Mon-Sat, before 1pm)) or via Banjarmasin. You will have to spend a night there before flying into Pangkalan Bun. Flights out of Pangkalan Bun do connect with onward flights to Jakarta. There is also a bus service between Banjarmasin. Please contact an Indonesian travel agent if you are considering this route.

6. Fly from Jakarta to Pontianak (West Kalimantan) and then on to PKB.
(cost Rp 990,000 on Kalstar (Mon-Sat) or Rp 789.000 on INDONESIA AIR TRANSPORT ( Everyday ).

The journey takes approximately 9 hours if you catch the PB Bus (air-conditioned, Super Executive Class) which leaves around 10am. There are several other bus companies operating on the route. Overnight in Pontianak and take a morning flight to PKN via Ketapang. Kalstar fly daily at 8.50am (Rp 765,000). Flights from Pontianak to PKN cannot be booked from the Overseas so you will need to book them on arrival. Allow extra time for this. You will need your Indonesian visa before arriving in Kuching. Fly from Denpasar (Bali) to Semarang (via Surabaya, Java)
Served by Merpati (Rp 800.000) Garuda, Silk Air and Wings Air

Kalimantan Orangutans Sactuary and National Park

(1) Tanjung Puting. Tanjung Puting National Park, just inland from the south coast of Borneo in Central Kalimantan, currently offers rehabilitation at several sites along its main river, the Sekonyer.

Tanjung Puting is coastal lowland, sitting on a peninsula jutting into the Java Sea. The peninsula is low-lying and swampy with a spine of dry ground that rises a few feet above the ever present swamp; nowhere does its elevation rise above 100 ft (Galdikas & Shapiro, 1994). About 205,000 ha of this region was declared a game reserve in 1935, much of representing good orangutan habitat (Aveling & Mitchell, 1982). It was made a National Park in 1982. The park officially covers 3,040 km2 of lowland dipterocarp and peat swamp forest. It is the largest protected forest in Central Kalimantan, one of the largest protected areas of tropical heath forest and peat swamp forest in Southeast Asia, and one of the most important wild orangutan areas in Borneo (Galdikas & Shapiro, 1994; Payne & Andau, 1989).

Camp Leakey, a site on the right branch of the Sekonyer River, was the main base for orangutan rehabilitation in Tanjung Puting from 1971 until the early 1990s. Camp Leakey was initially established by Dr. Biruté Galdikas for research on the resident wild orangutan population. Rehabilitation at Camp Leakey began informally in 1971, when Galdikas agreed with local authorities to accept ex-captive orangutans and assist them to return to free forest lives (Frey, 1978; Galdikas-Brindamour, 1975; OFI website, 1999).

Galdikas began using other sites within the park for orangutan rehabilitation from the late 1980’s (Tanjung Harapan, and briefly Natai Lengkuas). As of 1991 the intent was to cease rehabilitation at Camp Leakey because the camp had become increasingly crowded with rehabilitants, their offspring, and tourists. The crowding caused by the rehabilitants and their offspring probably stressed the wild population. The tourist influx undermined the rehabilitation process and increased the risk of introducing serious human diseases to the rehabilitant orangutans, who could then transmit disease to the wild orangutans.

The Indonesian government, via the national park authorities (PHPA), took over management of all orangutan rehabilitation in Tanjung Puting late in 1991. Since then, two new rehabilitation sites were opened for operation, a first at Tanjung Harapan and a second at Pondok Tandui. In 1995 new regulations came into law in Indonesia that prohibit the reintroduction of rehabilitant orangutans into areas currently supporting wild orangutan populations. Tanjung Puting supports an important wild orangutan population, so the aim is to terminate orangutan rehabilitation in the park. To handle the continuing influx of ex-captive orangutans in Central Kalimantan, a new rehabilitation site is under development at Nyaru Menteng, near the provincial capital of Palangka Raya.

(2) Bontang. A very small center specifically devoted to orangutan rehabilitation, but little known, operated for several years at Bontang on the edges of Kutai National Park in East Kalimantan. Bontang welcomed tourists, although relatively few visited because of its inaccessible location. It was closed in the mid 1990s when Wanariset took over all orangutan rehabilitation in East Kalimantan.

(3) Wanariset. Wanariset is a research centre dedicated to conservation-oriented research on tropical forests. It was established in the 1980’s by the Indonesian Department of Forestry, the Indonesian association of forest concession holders, and the Tropenbos Foundation of the Netherlands. It is part of the Forestry Research Institute, Samarinda, which reports to the Agency for Forestry Research and Development of the Indonesian Ministry of Forestry. Wanariset is not situated in a national park or reserve, but on land protected for research purposes 38 km north of the oil city of Balikpapan in East Kalimantan, along the main road to Samarinda.

Willie Smits, Wanariset’s Dutch team leader at the time, initiated an orangutan rescue and rehabilitation project at Wanariset in 1991 with the help of children at the local international school. The project was named the Orangutan Reintroduction Project. ORP’s focus remains the confiscation and rehabilitation of illegally held captive orangutans, but it increasingly devotes effort to a broader range of orangutan protection activities including surveys to identify good orangutan habitat, surveying wild orangutan populations, education, supporting wild orangutan protection efforts, etc.

ORP follows a rehabilitation program developed by Herman Rijksen, which emphasizes extensive medical screening and treatment, strictly limiting human contact, resocialising ex-captives to orangutans, and release into areas free of wild populations. ORP releases ex-captive orangutans in the triangle east of the Barito River and south of the Mahakam River, an area believed to be free of wild populations of orangutans. The reasons for orangutans’ absence are unknown, because the habitat resembles that of adjacent areas that do support wild orangutan populations (IBN-DLO, 1995). To date, ORP has released orangutans into two areas of protected forest—Sungai Wain and Gunung Meratus (Beratus)—that are distant and disconnected from the Wanariset facilities.

Sungai Wain is a water catchment forest with Protection Forest status (hutan lindung) located about 15 km north of Balikpapan and 20-25 km south of Wanariset. Wild orangutans have been absent from this forest since at least 1938 (Westermann, 1938). Officially protected is an area of ~11,000 ha (~ 27,000 acres) of lowland mixed dipterocarp rainforest with extensive swamp areas in the southern part. Around the protected areas of Sungai Wain forest lie another 10,000 ha of logged-over forest and swamp. The forest is bounded on the south by a canal, reservoir, and fencing; on the north by an uninhabited logging concession; on the west by the bay of Balikpapan; and on the east by farmland and the main Balikpapan-Samarinda highway (Smits et al., 1994). Despite its protection status, the forest has suffered considerable encroachment from adjacent human settlements and fires early in 1998 destroyed about 50% of the remaining good forest so that by mid 1998, only about 3500 ha of good forest remained.

The Meratus (Beratus) forest-block is a larger, more remote site. It constitutes an area of State forest land covered by lowland to hill rainforest with some swamp that lies some 30 km NW of Sungai Wain. Its centre has Protection Forest status (hutan lindung) but it was affected by logging incursions from the timber concessions that surround it until 1993. Its periphery is logged-over and has been abandoned by the concessionaires. On one side it borders onto the concession area of a timber production company. It is distant from human settlement, the nearest community being 50 km distant. In ecological terms, the Meratus forest-block is part of the hill and mountain rainforest covering the Pegunungan Meratus region, and the contiguous forest cover of the adjacent concessions.

The Ministry of Forestry accorded 1,200 km2 of this forest-block to the orangutan reintroduction project with Protection Forest status. The area allocated is covered with good quality lowland and hill forest that should offer excellent habitat for orangutans, although much of the area is at elevations greater than 500 m. Elevations in the area reach 1200 m; permanent wild orangutan populations are very rarely found this high. Negotiations are currently under way to increase the protected area available for orangutan reintroductions.

Bahorok Orangutans Center – North Sumatra – Indonesia

Sumatra, in Indonesia, is a natural reserve and forest land with acres and acres of forests, and woods, and a large variety of wildlife, avian life, flora and fauna. And, this aspect of Sumatra is an attractive option for tourists, especially those who love nature, and would like to spend time in the wilderness while on a vacation. One such attractive spot that attracts people is the Bohorok Orang-utan Viewing Centre.

Located just outside Bukit Lawang Gunung Leuser National Park, in Sumatra, the Bohorok Orang-utan Viewing Centre is about 90 kms from Medan. The Bohorok Orang-utan Viewing Centre is a famous rehabilitation centre that was set up in 1973, by two Swiss zoologists, Regina Frey and Monica Boerner, to help primates to get readjusted to the wild after confinement or dislocation.

The orangutans of Sumatra are an endangered species, with loss of habitat, and poaching pushing them towards extinction. The Bohorok Orang-utan Viewing Centre is an effort to preserve and save these animals that are quickly dying out. After it was opened in 1973, with funding coming from the Frankfurt Zoological Society (FZS) and the World Wildlife Fund (WWF), the Bohorok Orang-utan Viewing Centre has seen almost 200 orangutans released into the wilderness.

The Bohorok Orang-utan Viewing Centre is a center where a visitor can closely watch semi-wild orangutans, where they are being trained to return to their native habitat after being freed from captivity. In 2002, a new quarantine centre was set up outside Medan, as an additional facility with the Bohorok Orang-utan Viewing Centre. As this center, named Bukit Lawang Centre became operational, the Bohorok Orang-utan Viewing Centre has been restricted to be the home of old and sick orangutans.

The Bohorok Centre for ex-captive Sumatran orangutans was established in 1973 by two Swiss zoologists, Regina Frey and Monica Boerner, with funding originally provided by the Frankfurt Zoological Society (FZS) and the World Wildlife Fund (WWF). In 1980 the Centre was taken over by the Indonesian Government. Since then it has received virtually no outside funding, and it no longer operates as a rehabilitation centre for orangutans. It survives on a portion of the permit money paid by visitors. The rangers are paid by the Government.

Since it opened in 1973 more than 200 orangutans have been released. It is wonderful when rehabilitated females conceive and give birth in the forest. It means the centre has increased the orangutan population as well as giving the infant a chance to grow up in a protected forest area.

Although the Bohorok Centre no longer operates as a rehabilitation centre, Bohorok’s staff remain responsible for approximately 35 ex-captive orangutans who are free to come and go into the surrounding forest. The centre has been closed to admitting more orangutans since 1996. The centre no longer meets modern standards of species re-introduction. Furthermore, the area is already over-saturated with orangutans, and therefore not suitable for releasing more rehabilitants. Releasing ex-captive apes into areas of forest where wild populations exist also risks importing disease. For these and other valid reasons, Bohorok cannot be modified and updated to function again as a rehabilitation centre. The Indonesian government is winding down the project, and funds for maintenance and improvements have decreased.

The apes who remain at Bohorok still need to be cared for, facilities upgraded, further training provided for staff, and controlled eco-tourism implemented. This will require not only funding, but also a comprehensive local education programme to promote sustainable development at Bohorok.

The centre remains open to tourists, providing the incredible opportunity of viewing orangutans in the semi-wild on daily excursions to the feeding platform, an experience which galvanizes support for their conservation and well-being, and fuels the local economy.

It is essential that visitors refrain from touching or feeding the orangutans as they are susceptible to many human illnesses which their immune systems cannot deal with.


Mount Leuser National Park of Sumatra Indonesia

Mount Leuser National Park is one of the largest national parks in the world, containing over 800,000 hectares of virgin rainforest. The park is home to orangutans, gibbons, monkeys, elephants, tigers, and among the last of the Sumatran rhinoceros. There are research facilities for the study of primates, birds and insects, the Orangutans rehabilitation center at Bukit Lawang being the most popular with tourists. It is possible to raft Alas River from Ketambe to the Indian Ocean on a 4 – 5 day expedition. The journey takes us through exciting white-water rapids to the calmer, crocodile-infested waters of the lowlands. Basic accommodation is available at Ketambe.

The Leuser National Park of Gunung Leuser is probably the wildest in Indonesia, located in Southeast Aceh, can be reached from either Kutacane, or Takengon. This magnificent national park has a wealth of flora and fauna. The Leuser Ecosystem is an outstanding wilderness in Aceh northern Sumatra. It is one of the richest expanses of tropical rain forest in Southeast Asia. More than 2.5 million hectares in size, it is the last place on earth where elephants, rhinos, tigers, clouded leopards, and orangutans are found within one area.

The park is named after one of its highest point, the 3,381m Mount Leuser (Gunung Leuser). The highest point in the park is “Puncak Tak Punya Nama” (“The peak with no name”).

The first official statement of intent to protect the Leuser Ecosystem was signed in 1934. The Leuser International Foundation (a non-profit non-government organization) was established in the late 1990’s when the ecosystem was seriously under threat from illegal logging and wildlife poaching.
Geographically, the Leuser Ecosystem lies between 3-4.5° North and 96.5-98° East. It covers approximately 2.6 million hectares of tropical rain forest, encompassing 890,000 hectares of designated national park, as well as extensive areas of protection and production forests. The ecosystem contains two major volcanoes, three lakes, and nine major river systems that flow to the east and west coasts of the island.

The Leuser Ecosystem has an enormous level of biodiversity. It contains at least 127 mammal species, including the Sumatran elephant, Sumatran tiger, Sumatran rhinoceros, and Sumatran orangutan. About 8,500 different plant species grow in the beach, swamp, lowland, mountain and alpine ecosystems of the Leuser Ecosystem. Of the 10,000 plant species recorded in the West Indo-Malayan Region, 45% are found in the Leuser Ecosystem. Spectacular plants such as Rafflesia (the largest flower in the world) and Amorphophallus (the tallest flower in the world) are among the plants protected there.

Mount Leuser National Park is one of the biggest national parks in Indonesia (950,000 hectare). Actually, it’s a collection of various nature reserves and forests: Nature Reserve Mount Leuser, Nature Reserve Kappi, Nature Reserve Kluet, Sikundur Langkat Wildlife Reserve, Ketambe Research Station, Singkil Barat and Dolok Sembilin. Most parts of the national park lie in the region Aceh Tenggara (SE Aceh). Other parts are situated in the region east Aceh, south Aceh, and Langkat.

Mount Leuser National Park comprises more than 100 kilometers of the Bukit Barisan Mountains. Because of that, the park consists of steep, almost inaccessible mountainous terrain. The altitude ranges from 0 meter, in Kluet (South Aceh), to 3,381 meter, on top of the mount Leuser (Southeast Aceh). The Alas River cuts the park into an eastern and western half. Apart from mountains we find several other ecosystems: beach forest, swamp areas, lowland rainforest, alpine and mountain forest. In Bukit Lawang is the Orang Utan Rehabilitation Station and in Ketambe stands the Ketambe research station.

Covering both resilient Nangroe Aceh Darussalam and antique North Sumatra Province, most parts of the national park rest in the lush South East Aceh region, blessed with tropical fruits like mango, rambutan, durian, avocado, orange, papaya, and guava. The other parts are situated in the east Aceh, south Aceh, and Langkat of North Sumatra, known to produce world-class coffee and tobacco. Most visitors normally start their adventures in the national park through Bukit Lawang, North Sumatra, where you can always find the gentle giants of the jungle, the orangutans. Discover the gentleness of these sociable primates as your discovery of Sumatra begins right here.

Mount Leuser National Park, named after its highest peak, Mount Leuser (3,381 m), is one of the largest and the most diverse national parks in Indonesia, covering an area of 7,927 square kilometer in the northern tip of Sumatera, Indonesia. Embracing various ecosystems, the national park is in fact a cluster of various nature reserves and forests: Gunung Leuser Nature Reserve, Kappi Nature Reserve, Kluet Nature Reserve, Sikundur-Langkat Wildlife Reserve, Ketambe Research Station, Singkil Barat, and Dolok Sembilin.

The park is so extensive, it covers mangroves, beach and swamp forest, lowland rainforest, moss forest, and up to subalpine forest. When traversing its extraordinary landscape, enthusiastic adventurer like you will not be disappointed.

The Mount Leuser National Park, which is Taman Nasional Gunung Leuser in Bahasa, encompasses more than 100 kilometers of the Bukit Barisan Mountains, known for its steep, almost inaccessible mountainous terrains. The altitude ranges from beach area in Kluet (South Aceh), to 3,381 meter on top of the Gunung Leuser (Southeast Aceh). The breathtaking Alas River cuts the park into an eastern and western half, where your tropical thirst for adrenaline will be captivatingly fulfilled.

Around 130 species are identified in this park only. The mysterious Sumatran tigers, elephants, rhinos, Siamang monkeys, macaques, clouded leopards, reptiles, fish, and around 325 species of birds are among the endemic wildlife known to inhibit the park. Surely the trek to the inner park is more than just a great adventure to the last zoo you visited. Come and take in the experience living in a small friendly village, Ketambe, where the locals are naturally knowledgeable and ecologically hospitable.

Accommodation and Rooms
Rimba Lodge is perched on the edge of the Sekonyer River and surrounded by forest. Access is only by boat from the Port of Kumai. The timber Lodge is built in a series of adjoining elevated pavilions.

Each pavilion contains 3 rooms and has its own covered verandah and boardwalk to the river’s edge. Amethyst, Sapphire and Ruby rooms are adjoining in one large pavilion. The walkways also join the restaurant, reception and lounge and office. The Lodge is just a few minutes by boat from the orangutan feeding station at Pondok Tangui and mid way upstream to Camp Leakey. A resident troop of macaques are often seen around the Lodge and Proboscis monkeys are also often visible across the river. This is a Lodge that feels truly remote.

Orangutans Sumatran Of Indonesia

The Sumatran Orangutan (Pongo abelii) is the rarer of the two species of orangutans. Living and endemic to Sumatra island of Indonesia, they are smaller than the Bornean Orangutan. The Sumatran Orangutan grows to about 4.6 feet tall and 200 pounds in males. Females are smaller, averaging 3 feet and 100 pounds.

Compared to the Bornean Orangutan, the Sumatran Orangutans possess a lighter and longer pelage, a longer face, a smaller stature, and flanges that are covered in small white hairs.

Compared to the Bornean Orangutan, the Sumatran Orangutan tends to be more frugivorous and especially insectivorous.Preferred fruits include figs and jackfruits. It also will eat bird eggs and small vertebrates. The Sumatran Orangutans spend far less time feeding on the inner bark of trees.

Wild Sumatran Orangutans in the Suaq Balimbing swamp have been observed using tools. An orangutan will break off a tree branch that’s about a foot long, snap off the twigs and fray one end. It then will use the stick to dig in tree holes for termites. They’ll also use the stick to poke a bees nest wall, move it around and catch the honey. In addition, orangutans use tools to eat fruit. When the fruit of the Neesia tree ripens, its hard, ridged husk softens until it falls open. Inside are seeds that the orangutans love, but they are surrounded by fiberglass-like hairs that are painful if eaten. A Neesia-eating orangutan will select a five-inch stick, strip off its bark, and then carefully collect the hairs with it. Once the fruit is safe, the ape will eat the seeds using the stick or its fingers. Although similar swamps can be found in Borneo, wild Bornean Orangutans have not been seen using these types of tools.

NHNZ filmed the Sumatran Orangutan for its show Wild Asia: In the Realm of the Red Ape; it showed one of them using a simple tool, a twig, to pry food from difficult places. There is also a sequence of an animal using a large leaf as an umbrella in a tropical rainstorm.

The Sumatran Orangutan is also more arboreal than its Bornean cousin; this could be because of the presence of large predators like the Sumatran Tiger. It moves through the trees by brachiation.

The Sumatran Orangutan is more social than its Bornean counterpart. Groups of these orangutans gather to feed on the mass amount of fruiting on the fig trees. However adult males generally avoid contact with other adult males. Rape is common among orangutans. Sub-adult males will try to mate with any female, though they probably mostly fail to impregnate them since mature females are easily capable of fending them off. Mature females prefer to mate with mature males.

Interval birth rates for Sumatran Orangutan were longer than the Bornean ones and are the longest reported interval birth rates among the great apes. Sumatran orangutans give birth when they are about 15 years old. Infant orangutans will stay close to their mother for up to three years. Even after that, the young will still associate with their mother.

Both orangutan species are likely to live several decades; the longevity estimate can span for more than 50 years, with the oldest captive orangutan, Ah Meng, being born in 1960.[6] Nonja, thought to be the world’s oldest in captivity or the wild at the time of its death, died at the Miami MetroZoo at the age of 55.

The average of the first reproduction of P. abelii is around 12.3 years old with no indication of menopause.

In 2002, the World Conservation Union put the species on the IUCN Red List with critically endangered status. A survey in the Lake Toba forests, found only two habited areas, Bukit Lawang (defined as the animal sanctuary) and Gunung Leuser National Park.The survey estimated only 3,500 orangutans still live on Sumatra in 2002. Baby orangutans are often captured and sold as highly prized pets. In order to catch the babies poachers normally have to kill the mother first to prevent her from protecting her baby.



Orangutans Borneo of Kalimantan Indonesia

The Bornean Orangutan, Pongo pygmaeus, is a species of orangutan native to the island of Borneo. Together with the slightly smaller Sumatran Orangutan, it belongs to the only genus of great apes native to Asia.

The Bornean Orangutan has a life span of about 35 to 40 years in the wild; in captivity it can live to be 60. A survey of wild orangutans found that males are typically 75 kg (165 lb) and 1.2-1.4 m (4-4.7 ft) long; females averaging 38.5 kg (82 lb) and 1-1.2 m (3.3-4 ft) long

There is evidence that there was gene flow between the geographically isolated Bornean Orangutan populations until recently. The Bornean and Sumatran Orangutan species diverged 1.5 – 1.7 million years ago. This occurred well before the two islands (Borneo and Sumatra) separated. The two species of orangutan are more distantly related than the Common Chimpanzee and the Bonobo. Despite the difference, the two orangutan species were only considered subspecies until as recently as 1996, following sequencing of mt DNA.

The Bornean Orangutan has three subspecies:
* Northwest Bornean Orangutan P. p. pygmaeus – Sarawak (Malaysia) & northern West Kalimantan (Indonesia)
* Central Bornean Orangutan P. p. wurmbii – Southern West Kalimantan & Central Kalimantan (Indonesia)
* Northeast Bornean Orangutan P. p. morio – East Kalimantan (Indonesia) & Sabah (Malaysia)

The population currently listed as P. p. wurmbii may be closer to the Sumatran Orangutan (P. abelii) than the Bornean Orangutan. If confirmed, abelii would be a subspecies of P. wurmbii (Tiedeman, 1808). Regardless, the type locality of pygmaeus has not been established beyond doubts, and may be from the population currently listed as wurmbii (in which case wurmbii would be a junior synonym of pygmaeus, while one of the names currently considered a junior synonym of pygmaeus would take precedence for the taxon in Sarawak and northern West Kalimantan). To further confuse, the name morio, as well as various junior synonyms that have been suggested,[1] have been considered likely to all be junior synonyms of the population listed as pygmaeus in the above, thus leaving the taxon found in East Kalimantan and Sabah unnamed.

The Bornean Orangutan lives in tropical and subtropical moist broadleaf forests in the Bornean lowlands as well as mountainous areas 1500 m in elevation. It lives at different heights in the trees and moves large distances to find trees bearing fruit. Its diet consists of fruit as well as shoots, bark, mineral rich soil and bird eggs. It also eats insects but to a lesser extent than the Sumatran Orangutan.

The Bornean Orangutan travels on the ground more than its Sumatran counterpart. It is theorized this may be in part because there is no need to avoid the large predators which only exist in Sumatra such as the Sumatran Tiger.

The Bornean Orangutan is more solitary than the Sumatran Orangutan. Two or three orangutans that have overlapping territories may interact for small periods of time. Males and females generally come together only to mate. Rape is common among orangutans. Sub-adult males will try to mate with any female, though they probably mostly fail to impregnate them since mature females are easily capable of fending them off. Mature females prefer to mate with mature males.

Newborn orangutans nurse every 3 to 4 hours, and begin to take soft food from their mothers’ lips by 4 months. the first year of its life the baby clings to its mother’s abdomen by entwining its fingers in and gripping her fur. Babies stay with their mothers until they are about 8 or 9 years old and have a long childhood compared to other apes.
