Javan langurs (Trachypithecus auratus auratus) are small monkeys coming from Indonesia. At birth, young Javan langurs wear a bright orange fur. Then, as they grow older, their fur can stay orange or turn black-greyish, depending on the individuals.

Endangered species

Classified as “vulnerable” by the IUCN (International Union for Conservation of Nature), the Javan langur sees its numbers decrease because of the illegal exotic animal trade, of hunting, and because of the loss and splitting up of its habitat.

Des actions de protection

The Aspinall Foundation has developed a program of population reinforcement for Javan langurs in the Pusubgrawung forest, a protected area located east of Java. Supported by Beauval Nature, the objective of the project is to recreate a viable population of Javan langurs in this territory.

14 Javan langurs born in the Port Lympne Wild Animal Park in UK and in the ZooParc de Beauval in France have thus joined 5 wild individuals already living in the Javan reintroduction centre. In July 2016, Samui and Indah, two female Javan langurs have joined the Port Lympne zoo, a park managed by the Aspinall Foundation, to meet their trip fellow creatures.

In 2017, these animals will be released into a wild area carefully selected by the program members after several population and habitat studies.

The animals need to be well prepared before they can be reintroduced, and to be regularly followed up once they have joined the wild: their diet has been changed to adapt them to the plants present on the site, their behaviour has been observed to be sure of their well-being in their new environment… A wooden structure will be set up in the area so that the animals can shelter in it, and a reference point will be made during the first days following the release.
