The forests of Borneo are under the threat of disappearance due to the overexploitation they suffer for different reasons. Fortunately, some organizations struggle to try to avoid or reverse this process. On November of 2017 I had the opportunity to join a team of IAR (International Animal Rescue) in their mission to release 4 orangutans that had to be reintroduced. Two of them where confiscated animals who were grown in their reintroduction program for the last years and the other two where wild orangutans that had to be relocated due to the threats of death they were suffering in their habitat due to the proximity of local plantations. The number of virgin forests in Borneo, sadly, is decreasing. Thus, reintroducing orangutans in a place far enough away from civilisation to guarantee their prosperity becomes an epic journey of several days across the island using various transports. The logistics of this type of expeditions is complicated, and should include several cars, boats, porters, food and veterinary material among others. Despite that, fortunately, the rate of reintroduction of the IAR is very high and they carry out a large number of successful reintroductions.
