Programme roles

Direct Conservation icon  Insurance
Gibbon species are severely threatened in the wild and could potentially benefit from having in situ insurance populations. The aim of the gibbon EEPs is to have demographically stable, genetically healthy and behavioural competent populations to allow reintroduction in the far future if needed and in accordance with IUCN reintroduction guidelines. Other gibbon EEPs have a higher priority for insurance population then the Lar gibbon as other ex situ populations exist. 
Indirect Conservation icon  Education (Inside and outside range)
Gibbons provide excellent opportunities for education messages about small apes in general, taxonomy of gibbons, unique locomotion of gibbons, forest life in Asia and the threats faced by gibbons in the wild. In particular negative impacts on this species of photo props with gibbons as it has enhanced the trade in gibbons.  

• Research
Research is needed on behaviour, nutrition, genetics and veterinarian aspects and general health. 

Fundraising is needed for projects recommended by the Gibbon TAG. 

Programme numbers

In June 2021, the Lar gibbon EEP had 376 animals in 137 institutions.

Programme highlights

  • The IUCN SSC Primate Specialist Group has recently published best practice guidelines on responsible images of non-human primates. These guidelines aim to reduce the potential costs of primate images to primates, their welfare and conservation in and ex situ. This is relevant for siamangs, as they are sometimes used as photo-props in range countries, resulting in an increased trade in siamangs and other gibbon species.
  • IUCN Gibbon SSC has a Facebook page where they regularly publish news stories and updates about gibbon species. 
  • EAZA published its 2021 Annual TAG Report.
