An overarching focus of our work in orangutan reintroduction programs is orangutan release. As one of the BOS Foundation's programs, RHOI helps provide natural habitat for rehabilitated orangutans from the Samboja Lestari Rehabilitation Center to the Kehje Sewen Forest in East Kalimantan.
We are still working to identify additional, suitable forests in East Kalimantan to accommodate the hundreds of orangutans still in our care at our rehabilitation centres and those who may be rescued in the future.
From the beginning of RHOI's establishment in 2009 to date, we have successfully released 121 orangutans in Kehje Sewen. In fact, the orangutan reintroduction program does not stop until the time the orangutan is successfully released. There needs to be post-release monitoring. We call this Post-Release Monitoring (PRM).
Post-release monitoring (PRM) is essential to assess the health, behaviour, and survivorship of released orangutans. The challenge is to ensure that these new populations are healthy, well established, and adequately protected long into the future. This combination of post-release monitoring and medical intervention, which we provide only as needed, aims to ensure that our orangutan reintroductions are successful, and that each individual orangutan is afforded the best chance of survival.
In addition to PRM, we also conduct forest patrols, and phenological surveys at our release site, in Kehje Sewen. We remain committed to reintroducing orangutans into their natural habitat to establish new, viable wild populations and bolstering the conservation prospects of the species. Once orangutans have acquired all the skills they need to survive in the wild, our teams engage in the detailed planning required for each release to ensure that it can be carried out safely and successfully.
