The Fascinating Science of How Trees Communicate, Animated

“Trees are the foundation of forests, but a forest is much more than what you see.”

“The tree which moves some to tears of joy is in the eyes of others only a green thing which stands in the way,” William Blake wrote in his most beautiful letter. Walt Whitman found in trees a model of existential authenticity. Hermann Hesse saw them as the wisest of teachers. Wangari Maathai won the Nobel Peace Prize for her noble work of planting trees as resistance and empowerment.

But trees are much more than what they are to us, or for us, or in relation to us. They are relational miracles all their own, entangled in complex, symbiotic webs of interbeing, constantly communicating with one another through chemical signals dispatched along the fungal networks that live in their roots — an invisible, astonishing underworld only recently discovered, thanks to the work of Canadian forest ecologist Suzanne Simard.

In this lovely short animation from TED-Ed and animator Avi Ofer, Camille Defrenne — one of Simard’s doctoral students at the University of British Columbia, studying how the interaction and architecture of root systems relate to forest dynamics and climate change — synthesizes the fascinating, almost otherworldly findings of Simard’s lab:

Simard, whose research was foundational to German forester Peter Wohlleben’s wildly popular book The Hidden Life of Trees: What They Feel, How They Communicate, discusses her work and the improbable path that led her to it in her wonderful full-length TED talk:

Yes, trees are the foundation of forests, but a forest is much more than what you see… Underground there is this other world — a world of infinite biological pathways that connect trees and allow them to communicate and allow the forest to behave as though it’s a single organism. It might remind you of a sort of intelligence.

Complement with a wondrous picture-book about the forest, Annie Dillard on how mangrove trees illuminate the human search for meaning, and biologist David Haskell on what a dozen of the world’s most unusual trees taught him about the art of relationship, then revisit three other lovely animations by Avi Ofer: Neil Gaiman’s existentialist dream (also involving trees) narrated by Amanda Palmer; Jane Goodall on her remarkable life-story; and philosopher Skye Clearly on why we love.
