Project information

Saving the Javan Gibbon

With a wild population estimate of fewer than 2,000 individuals, the Javan Gibbon is one of the rarest and most endangered of al gibbon species. Building on TAF's success in the captive breeding of Javan gibbons by setting up a rescue and rehabilitation centre in West Java for rescued gibbons.

Ongoing project.

  • Need


    The species is considered to be amongst the highest primate conservation priorities in the world. Unique to Java, one of the most densely populated areas on the planet, it is estimated 98% of gibbons forest home has been destroyed. The main threats are from poaching, capture o


    Confiscation of gibbons that are held as pets, working with local/national authorities to rescue thse animals. Build a rescue, rehabilitation and breeding centre within 20 hectare site. Where can provide the specialist care we anticipate the rescued gibbons will require for duration of their life. Build on our captive breeding success to develop a reintroduction programme in future. Set up awarness campaign to inform local people of protection need for this primate.

  • Aims

    Aim 1

    Setting up a captive breeding centre in Java for gibbons that have been rescued or confiscated


    » Within 20 hectare site plan to build six enclosures, veterinary centre and fruit store. Where we can provide the high level of care required.

    What success will look like

    Success will be completion of rescue centre facilities, and successful confiscation of 80 animals currently held illegally

    Aim 2

    Captive breeding programme with long term aim of reintroduction


    » Build on successful captive breeding programme at Kent wild animal parks & africa gorilla reintroduction project to reintroduce rescued gibbons

    What success will look like

    Success will be rehabilitation of rescued gibbons, introducing pairs for breeding, identification of suitable reintroduction site and stategy for release of indivudals

    Aim 3

    Set up permanent research facility


    » Researchers will study wild gibbon behaviour & develop improved reintroduction strategies

    What success will look like

    Success will be establishment of research facility who are producing peer reviewed papers on wild population behaviour and reintroduction stategies

  • Impact


    Increase in the wild population of Javan gibbon, protection of range areas to increase corridors facilitating population movement.
    We will demonstrate the success of this project by the number of gibbons that are confiscated and rehabilitated. An awareness and education campaign set up to promote conservation of Javan priimates, with workshops and seminars having been held. In-situ research programme set up.


    The risks inherrant in this project of illegal pet trade, hunting and deforestation will remain.
    TAF has signed a memorandum of understanding with the Forestry Dept in Indonesia as part of a collaborative partnership to ensure
    an increase in the protection for, and improve scientific understanding of the Javan gibbon, with focus on tropical forest habitat and reintroduction


    Rather than a set programme of feedback, we will let you know about key landmarks and progress, and share with you stories of some of hte primates we rescue and help. In this way, we hope to give an inspiring insight into impact of gift.
