The construction of a road through the forests where orangutans used to live in Sumatra, Indonesia has split the Sumatran orangutan community in two and raised concerns that inbreeding could affect their health and ultimately lead to their extinction.
Conservation groups Sumatran Orangutan Society (SOS) and Tangguh Hutan Khatulistiwa, with help from the government, built a canopy bridge in the hope that the orangutan community could use it to pass between the two forests.
However, the bridge has not been used for two years. That was until one orangutan bravely crossed to the other side.
SOS CEO Helen Buckland told the BBC how the exciting, long-awaited crossing could significantly change the situation for primates.
