Project overview

Reintroduced gibbons in Southern Sumatra and Java disappear into dense rainforest canopy the moment they're released - but their calls travel for miles.

The challenge

Released gibbons are almost impossible to track visually, and biodiversity within the reintroduction sites has never been systematically measured.

Our solution

Solar-powered forest recorders paired with AI-driven voiceprint mapping (SonicDNA) - filtering noise, matching calls to individuals, and confirming location without ever recapturing an animal.

Tech deployed

  • Bioacoustic recorders
  • SonicDNA voiceprint mapping
  • AI noise-filtering
  • A Siamang Gibbon calling with its arms raised in the canopy.
  • Photograph from the Sumatra reintroduction programme.
