Post Release Monitoring Project Update

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 this 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. This will be achieved by daily tracking of orangutans fitted with implanted radio telemetry (IRT) and monitoring and recording their behavioural patterns. 

We are delighted to provide you with this latest update:

Our growing Tabin family is thriving. Otan and her son Spike, and Eyos and her new baby Camelia are both growing really fast and behaving normally. In fact, we’ve noticed how much faster Camelia has been developing compared with Spike at the same age; she was trying solid foods earlier and she also seems braver too, venturing up to four metres away from her Mum already within just six months of being born! I suppose you could call that: girls 1, boys nil!  We were absolutely delighted when we discovered both Anekara and Hope were also pregnant and we are so excited to announce we now have another two babies called Daniel and Doris!  This means our programme has not acheived a 100% birth success rate!

OAUK's primatlogist speaking in July said "Since we began our rehabilitation work in Tabin we've reintroduced four females. I'd say that one of the best ways to judge the success of reintroducing female apes is to see if they're able to reproduce while living free in the wild. I'm therefore absolutely delighted to announce that all of ours have now become mothers! This year Hope, and then Anekara, gave birth to Doris and Daniel respectively, to join Otan and Eyos with their firstborns. Spike, our oldest, is now two years old while Daniel, our youngest, is just two months! We've created an entirely new generation of wild born orangutans through our hard work and compassionate approach to their post release care.

What we're doing in Sabah is giving these animals the future they deserve, the future that we, as a species, denied them through our own selfish activities in the past. It has been the most satisfying journey to see these beautiful animals go through pregnancy, give birth, and care for each of their babies so tenderly. We keep going with what we do, as we know that we're doing it right - our 100% birth rate reflects my team's success."

Let's now forget Mico - he is doing well too, although because all the girls now have babies, he’s been forced to spend more time on his own as they’re too busy to look after Mico too! We’re not too concerned about this though, because his diet has been brilliant after learning so much from everyone since last year.
