What to know about Artificial Intelligence in Ecology

Researchers have developed a new AI training method called 'cross-model confusion mapping' to reduce false alarms when using acoustic monitoring to detect possums in New Zealand. By using BirdNET to identify sounds that AI often confuses with possum calls, the team improved the accuracy of detection models in real-world forest environments.

What happened

Possums are among New Zealand’s most destructive introduced mammals.

Why it matters

They damage native forests, prey on wildlife and remain a major target of the country’s Predator Free 2050 programme.

Common ground

But removing most possums from an area through predator control is only part of the challenge.
