the Gibbon SSP

The Gibbon Species Survival Plan (SSP) oversees breeding, transfers, and animal management for three populations of gibbons in AZA-accredited and partner institutions in North America.

Managed species include:

Lar gibbons (Hylobates lar)

White-cheeked gibbons (Nomascus leucogenys)

Siamangs (Symphalangus syndactylus).

Several additional gibbon species are housed in North American institutions but are not managed by the SSP. The Javan gibbon population is managed as part of the Australian-based Javan Gibbon Management Committee. While the Gibbon SSP does not maintain studbooks or make recommendations for these species, we are available to help with management issues or to connect holding institutions to facilitate transfers and improve social groups.

Non-managed species include:

Yellow-cheeked gibbon (Nomascus gabriellae)

Grey gibbon (Hylobates muelleri)

Agile gibbon (Hylobates agilis)

Pileated gibbon (Hylobates plieatus)

Javan gibbon (Hylobates moloch)

Eastern Hoolock (Hoolock leuconedys)
