A few months ago, I saw several posts on social media about how trees communicated with each other. At the time, I didn’t bother to look into it any further, but recently a friend put up a link to a TED talk by Canadian scientist Suzanne Simard (embedded below).
She came from a family closely associated with trees – her grandfather was a logger and when she started work, she also found herself in the logging industry. Fortunately, the relentless destruction caused by intensive logging and clear cutting of forests didn’t rest well with her conscience and she could no longer be a part of it.
She went back to studying and researched a lead into tree to tree communication. She has been able to prove that many species of trees work together, asking for carbon as an example, and other adjacent trees respond by giving it. But not just carbon – many other of the essentials of tree life can be asked for and given in a two-way relationship.
How did I miss this? It’s so amazing, breathtaking and groundbreaking that it should be major news shouldn’t it? As the realisation and extent of what’s happening starts to sink in, it’s really making me think, on a deep level about trees, about nature and about the part humans play, particularly in the destruction and use of trees.

Humans have clearcut old growth forests all around the world, and continue to do so right now. Deforestation is not just an issue in the Amazon, it’s an issue in the USA, Canada, Sweden, Finland, Russia, Borneo, China and so on. When you clearcut, you don’t just kill the trees, you destroy the entire ecosystem that trees are the hub of, so fungi, insects, birds, mammals are decimated often to the point of no return.
And when ‘we’ replant forests, we plant the best thing for humans – cash crops – monocultures of the trees that will grow fastest and tallest and yield the highest profit. No longer do we have the diversity that was once there, and therefore, the mono cultures are prime sites for attack by pests and diseases.
I’m sure I read last week, that Sweden had logged over 95% of its old growth forests (if anyone can verify this, please let me know…). Although we tend to think of Sweden as a country covered in forest, it seems humans have stripped it bare and replanted commercial monocultures. The same is true of Finland according to some of the writing of Finnish philosopher, Pentti Linkola.
So, does the news that trees communicate affect you in any way? I’d love to hear your thoughts!
