It is one of the most endangered primates in the world. The Hainan gibbon lives on the island of the same name, in China. It is an arboreal monkey that moves by swinging from tree to tree. In 2014, a typhoon hit the island. To safeguard its habitat and therefore the species, local specialists install ropes 15.8 meters long. Five years later, the results are final. These installations made it possible to reconnect natural forest corridors and thus allowed the preservation of the species. Photo
