About the SSA

The SSA is a group of more than 80 gibbon experts globally, with a shared vision of conserving the world’s gibbons. The SSA contributes to gibbon conservation through:

  • Strengthening coordination among gibbon conservation projects worldwide;
  • Increasing awareness of scientifically-sound practice in gibbon conservation;
  • Providing IUCN-endorsed guidelines to conservationists, field scientists and decision makers;
  • Developing Conservation Action Plans that clarify priorities in gibbon conservation for practitioners, decision makers and donors;
  • Ensuring the IUCN Red List of Threatened Species as a decision tool is thorough and up-to-date.
  • Providing direct technical support to implementing projects engaged with gibbon conservation.
