How trees talk to each other | Suzanne Simard

Dr. Suzanne Simard discovered that trees can communicate with each other because their root systems are connected by networks of beneficial fungi. These root and fungal networks are now referred to by scientists as the “wood wide web,” which trees can use to share water and nutrients with neighbour trees of the same species. Her research explains that trees communicate through electrical, visual, and olfactory means.

Further research has shown that trees react to invading pests by releasing defensive compounds through their leaves. These compounds float on the breeze to neighbouring trees who trigger their own defence before disease take hold.

Sinard formed the inspiration for the character, Patricia Westerford, in the novel The Overstory which explores the lives of a number of forest activists, their activities, their motivations and their struggles. The work Sinard has pioneered has inspired more than works of fiction, but a whole new branch of scientific endeavour.
