Golden-headed Langur

Region: Vietnam


Status Ongoing

The miserable record as one of the most endangered primate species in the world keeps the Golden-headed Langur or Cat Ba-Langur (Trachypithecus poliocephalus). This primate species only range at the Cat Ba archipelago, the famous World Heritage Halong Bay in northern Vietnam. In November 2000 the "Cat Ba Langur Conservation Project" started on the Island of Cat Ba.

What we do

  - Immediate protection of the remaining animals and securing their habitat
  - Providing a natural social structure within the monkey groups;
  - Protection and exploration of the biodiversity on Cat Ba;
  - Development of capacities in the national park.

    Our achievements

    Numerous successes have been recorded so far. In the first year of the project a strict protected area was established inside the national park. This so-called "langur Sanctuary" is home to the largest reproducing group of langurs and is not accessible for tourists and local people. After the construction of two ranger camps now 20 rangers supervise this area. Langurs outside this area are protected by local "langur guards". They do educational work for the local people and are allowed to expel people out of the area and seize weapons.
    In cooperation with the local forestry authority' forest protection groups have been established. These groups are also locals who carry out patrols and do also educational work.
    They ensure the conservation of the habitat to enable an increasing of the langur-population.
    A significant part of the activities of the project focuses on the direct support of the national parks as the main authority in matters of biodiversity and nature conservation.
    This includes providing much needed technical equipment for rangers and expert advice in all aspects of conservation measures within the park and training of park employees.
    The illegal hunting of monkeys has been terminated because of the surveillance of the park. Since the beginning of the project the stock of the langurs has increased. From that point of view the CatBa-Langur is the only primate species in Vietnam, whose numbers grow in their natural habitat.
    Another milestone in the protection of primates was the expansion of the national parks in 2006. Since then all langur groups live within the national park.

    The future

    The primary task for the future is to protect the remaining animals and their habitat. To enable a natural social structure to the animals and to prevent the fragmentation of populations, translocation operations should be carried out. In 2012 the first translocation took place. Two female langurs were successfully moved into the langur sanctuary and joined other langur groups soon after. 

    Stiftung Artenschutz is grateful to the Apenheul Primate Conservation Trust and the Gemeinschaft Deutscher Zooförderer e.V. (GDZ) for their generous support.

    The Foundation received a major contribution by Langnese - we deeply acknowledge the generosity.
