Trees Talk to Each Other Underground

Through a vast network of fungi known as the ‘Wood Wide Web’, trees share nutrients and information with one another.

Beneath your feet lies an underground internet made of fungi. Known as the Wood Wide Web, it connects trees and plants, allowing them to share nutrients and warning signals.

When one tree is attacked by insects, others nearby can boost their chemical defences in response. Some trees even share sugars with their struggling neighbours—proof that forests may be more cooperative than competitive.
