PRMP Update - Ganang & Rosalinda


It is imperative to ensure the orangutans are successfully adapting after their reintroduction into the wild. Without constant tracking and collecting this data it is unknown whether the rehabilitation process has been successful and whether they will survive without further support, as no prior research has been undertaken.

It is ultimately anticipated that our research will contribute to improving the survival prospects of all reintroduced Great Apes in Africa and Asia. The PRMP project has the potential to improve the pre-release rehabilitation protocols in use both in Malaysia and Indonesia, by creating a blueprint for rehabilitating and releasing orphaned apes.

In May 2016, two female orangutans Ganang and Rosalina were transported from Sepilok and released into the Tabin Reserve. They have been closely observed by our Post Release Monitoring Team during this time and we would like to update you on how they are getting on.

Settling into a brand new environment can be a stressful experience and both Ganang and Rosalinda needed time to adapt to their new surroundings.

To start with Ganang showed quite limited foraging skills so the PRMP team felt that it was necessary to provide some supplementary food for her. This would help to maintain her body condition at an acceptable level whilst still encouraging her to look for her own wild food. After two months, Ganang was becoming braver at travelling through the forest and she appeared to be slowly acclimatising to her new surroundings. She has continued to improve upon her foraging skills since then and is becoming more and more confident and independent as time goes on. She will often make herself a fresh nest to sleep in and she moves quickly through the forest. The team are still closely monitoring her and making sure that she stays happy and healthy.

Rosalinda was a little more nervous of her new surroundings to start with. The team would observe her retreating to the upper canopy if she heard other animals below and she would often stay in the same place for long periods. After a couple of months in her new environment she appeared to be becoming more settled but she still wasn’t foraging for her own food very much. The team continued to give her supplementary food to prevent her from becoming too hungry and dehydrated.

Rosalinda is now showing signs of foraging for basic foods which is good news. Although her progress to becoming fully independent may have been a little slow it is encouraging and we are looking forward to seeing how both of these orangutans continue to adapt to a life in the wild.
