Sumatran Orangutan

Orangutans are often animals high on the list that people wish to see one day. Orangutans are the only great ape that lives outside Africa.

While fossils show that at one time, it was found on the mainland of Asia, the Orangutan is now restricted to the islands of Borneo and Sumatra. The Orangutan was first scientifically described in 1779 by Dutch anatomist Petrus Camper. This page is devoted to the Orangutans of Sumatra.

As with all great apes, the Orangutan is a keystone species and by saving its habitat, we save many thousands more as a by-product. The greatest threat has been palm oil plantations – while in theory these are created to reduce carbon emissions, it is questionable as to whether these plantations could ever be carbon negative. Building it on land that has to be cleared of rainforest, means that these palm oil plantations will have huge carbon footprints, which are likely to take over a century to pay off. As such it is not useful for climate change mitigation.
The orangutans of Sumatra are classed as critically endangered.

They are currently thought to number around 14,000. As always, we hope to add many destinations for Orangutans in the near future, do get in touch if you wish to list somewhere in their range. Below, any listings that might get added in the future, you will find all the articles we have written on Orangutans.

The Borneo and Sumatran Orangutans were only recognized as separate species in 1996

In many places politicians are almost expected to give themselves extra benefits – indeed those who do not, are often quite notable for standing out. In this case, after arresting the politician his house was raided, when the animals were found.

Life is hard in the Indonesian rainforest – compared to Africa and South America, there is very little to be found to eat (except in specific areas. As a result, orangutans become solitary, with the only time they are seen together is a mother with young, or a courting couple. Another problem, is demonstrated here …...

It is just 5 years since the Tapanuli orangutan was described. Despite this Orangutan being restricted to an area of Northern Sumatra, it is more closely related to the Bornean Orangutan than the Sumatran one. This might be the clearest indication of how long this species has been separate from its cousins. The Tapanuli Orangutan …...

I personally couldn’t see how an environmental check could make it through if the building of the dam, would completely eradicate one of the eight great apes on earth. However between the environmental challenges, the current ongoing pandemic and problems financing the project with many of the large world banks not keen to be associated …...

It would appear that chimpanzee medicine is quite a complicated field. This is a significant range of conditions that can be treated, though it should also be noted, that this knowledge is likely to be shared in the group, as no one individual will have seen their mother suffer from all these conditions. While gorilla …...

One of the problems with cutting down rainforest, it often what is left is so fragmented that it is useless for conservation. Remaining blocks of forest must allow a viable population of the rarest creatures, in order for the animals not to need to travel outside protected areas. In Borneo, like in Sumatra, there has …...

The wildlife of Indonesia now often looks like relatively unique to those islands. This is not the natural state of affairs. 60,000 years ago, a cousin of the orangutan lived on the mainland. Unfortunately, what appears clear, is that humans were responsible for the extinction of these animals as with so many more. There are …...

This proposal would mean that Indonesia could cut down all its rainforest and replace them with Palm Oil, and would have engaged in zero deforestation. This has to be condemned globally, There are myriad problems with this. The destruction of the rainforest would release billions of tonnes of carbon into the air. Palm oil, will …...

Indonesia is pressing ahead with its desire to build a dam in the Sumatran rainforest. Now when the Dam is filled and floods this vast area of rainforest, all the carbon currently stored in the trees will be released back into the air- either as carbon or as meeting due to the breakdown of the …...
