AI-assisted surveillance for wildlife is an 'urgent need'

28% of all plant, animal species are now at risk of extinction

The endangered Geoffrey's spider monkeys that dangle high in the rainforest canopy are elusive and hard for scientists to track.

So biologist Jenna Lawson hid 350 audio monitors in trees across Costa Rica's lush Osa Peninsula to spy on them.

The devices recorded the sounds of the forest and surrounding countryside for a week, collecting so much data that Lawson could have spent years listening to it all.

Instead, she fed it into artificial intelligence systems trained to instantly recognize spider monkey calls and detect where the animals traveled. One of the world's largest acoustic wildlife studies when Lawson began the project in 2021, it revealed troubling findings about the health of a treasured wildlife refuge.
