After our first release of seven orangutans into the Bukit Batikap Protection Forest was completed, on the following day, 18th of February, the same hevilift helicopter flew to our Juq Kehje Swen site, a pre-release island located in Muara Wahau District, East Kalimantan. There, the helicopter provided airlift for our second group of releasable orangutans, involving three adults: two males and one female, brought from our Samboja Lestari Orangutan Rehabilitation Centre by truck the day prior.

Now, the journey for these three orangutans entered its final stage. Following the early morning arrival of the group at Juq Kehje Swen the final leg of travel to the forest was ready to commence, but had to be delayed due to thick cloud cover in the area. Finally, at around 2 p.m. local time the weather finally improved and the release could commence. The team immediately flew Juve, Freet, and Britney to the drop point on the northern side of the Kehje Sewen Forest, where the three transport cages would be opened simultaneously at their respective release points. The journey, which usually takes more than 24 hours by truck, took only 30 minutes by air!

The orangutans, most of whom had undergone a lengthy rehabilitation, were successfully released in to the protected and remote forest to enjoy true freedom. With their forest school skills and foraging abilities at the ready, we are certain they will enjoy living and exploring their new homes in the wild. Our Post-Release monitoring team will be right there to make sure this is the case.

As the helicopter flew away with a dissipating roar and empty transport cages swinging on the sling underneath, the team was filled with emotion. The struggle to rehabilitate these orangutans and finally return them to the forest was over. It would now be up to the post-release monitoring teams to collect observation data on these released orangutans and conduct regular patrols to ensure their safety and well-being in the forest.

With the ten orangutans successfully released, members of the release team can now turn their focus to the next group of release candidates at the BOS Foundation’s rehabilitation centres.

We can’t wait to release more orangutans in the forest this year!
