Please read the orangutan update below written by our partners at the Sumatran Orangutan Conservation Programme. Together we are working to protect the habitat and future of all three critically endangered species of orangutan:

On Wednesday 26th August, 2020, the orangutan post-release monitoring team at the SOCP’s Jantho orangutan reintroduction site, in Aceh province, came across an adult female orangutan. After a quick check to see if they could figure out who it was, they noticed that she was carrying a young infant, no more than a few months old! The baby orangutan is male and is the third baby orangutan born in Jantho since the SOCP's Orangutan Reintroduction Programme began releasing orangutans into the Jantho Nature Reseve in 2011. Mother and baby both appear to be healthy and are behaving just like wild orangutans would. The infant is being carried properly by his mother and has been seen breastfeeding without difficulty on numerous occasions.

After checking some earlier photographs the team are confident the mother is 'Edelweiss', actually the very first orangutan to be released at Jantho back in 2011. After her release she immediately moved away from the camp area and deep into the forest. On February 11, 2020, a female orangutan strongly suspected to be Edelweiss was observed not far from the orangutan reintroduction site and at that time she was showing signs of being pregnant.

The aim of SOCP's orangutan release program at Jantho is to build a new, wild population of Sumatran orangutans (pongo abelii) as a "safety net" or "backup", should a of catastrophe befall the remaining truly wild populations in and around the Leuser Ecosystem. This is especially important in the midst of the current pandemic, as whilst the scientific evidence suggests orangutans and the other great apes are susceptible to infection by the SARS-CoV-2 virus, the effect it might have on them remains entirely unknown.

To date, more than 120 individual orangutans have been successfully released into the Jantho Nature Reserve but many more are needed before the population could be considered genetically viable and self-sustaining for the long term. For this reason, every orangutan released or born in Jantho’s forests is extremely significant and important, and gives new hope for the future of this critically endangered species.

Director of the Sumatran Orangutan Conservation Programme, Dr Ian Singleton said “We always knew it would be several years before we really started to see infants being born on a regular basis among the new population of orangutans we are creating in Jantho. This is because most of the orangutans we release there are 5 to 8 years old, whilst wild orangutan females tend to be around 15 years old on average when they have their first infant. It's great to see these new infants starting to appear though, and it's especially rewarding when you think about all the hard work, spanning many years, that goes into reintroducing each and every one of the orangutans we have released to date. That these new infants have never known captivity and human contact is also extremely heart-warming, and hopefully they never will, unlike their parents, whose own mother’s were almost certainly killed during their original capture and some of whom have endured years chained by the neck or kept in tiny cages at the hands of their illegal owners. The orangutans we are releasing in Jantho, and those now being born there, really are the founders of this entirely new wild population, and it's never been more important to have these ‘back up’ populations as we face the extremely worrying prospect of SARS-CoV-2 infections passing from humans to orangutans, both in captivity and in the wild”.
