A team of volunteers from the animal conservation charity Aspinall Foundation Indonesia recently released five Javan langurs, including one male and four females, to the wild at Malang Selatan forest conservation in a bid to reinforce their population.

Listed as one of the vulnerable endangered species by the IUCN (International Union for Conservation of Nature), the Javan langur (Trachypithecus auratus), a primate species endemic to Indonesia, sees its number dwindle over the years due to hunting, animal trade and habitat destruction.
