“A force hums in the heart of wood…the tree is saying things, in words before words.”

~ Richard Powers, “The Overstory”

“Trees are sanctuaries. Whoever knows how to speak to them, whoever knows how to listen to them, can learn the truth.”

~ Herman Hesse

“The clearest way into the Universe is through a forest wilderness.”

~ John Muir 

Recent studies confirm what poets & dreamers have always known in their hearts: the trees are talking to each other.

A revolution has been taking place in the scientific understanding of our arboreal friends. Biologists, ecologists & foresters are observing that trees have a quantifiable communication system and intelligence.   We are learning that the forest is a community that cares for its own. Trees are social beings who work together for the survival of the whole.

There is a growing body of evidence, pioneered by forest ecology professor Suzanne Simard, which shows that trees communicate through interconnected root systems, in collaboration with fungal networks. This symbiosis forms what is known as “the wood wide web.”

This unifying network is composed of mycorrhizal fungi, of which there are many different species. The fungi send out gossamer-fine threads through the soil and weave into the tips of plant roots, bonding at a cellular level and creating a super-organism.

This collaboration of roots creates an information superhighway, functioning like an underground organic internet. The wood wide web connects whole forests, enabling trees, not only to communicate with one another, but also to share resources.

For example, a tree which receives an excess of sunlight will transmit the resulting nutrients via the wood wide web to a tree that receives only shade. Healthy trees have been known to nurse felled friends, keeping stumps alive for as long as centuries. Parent trees nourish their saplings via the wood wide web, and will even reduce their own root growth to make room for their offspring.

Forest dwelling networks of trees warn one another of danger–-drought, predators, or disease, for instance. They do this by sending electrical signals through their root systems, simultaneously releasing molecules into the air; chemicals which act as messengers. Information can be transmitted in as little as seconds, or take as long as days.

Responding trees then alter their behavior, releasing chemical defenses to ward off predators or conserving water in the case of a drought warning. Trees will even alter their chemical composition in response to warning signals sent by friends under attack, making their leaves taste more bitter to an influx of a certain predator. In short, they work together to survive and thrive.

How might our own communities improve if we took our inspiration from the forest? What does this new understanding of trees have to teach us? Nature is wise. She knows that in giving, one receives, and that the benefit of one improves the whole.

“A tree can be only as strong as the forest that surrounds it,” notes Peter Wohlleben, arboreal ambassador & author of the best-selling book,  “The Hidden Life of Trees: What They Feel, How They Communicate – Discoveries from a Secret World.”

As Biology professor, George David Haskell notes: “Dogmas of separation fragment the community of life; they wall humans in a lonely room. We must ask the question: ‘can we find an ethic of full earthly belonging?’” (“The Songs of Trees.”)

Theoretical physicist David Bohm notes that the process of dividing the world into parts is a convenient way of thinking when applied to practical matters. But then we become fooled by our own fragmented perception.

“Man thus obtains an apparent proof of the correctness of his fragmentary self-world view, though, of course, he overlooks the fact that it is he himself, acting according to his mode of thought, who has brought about the fragmentation that now seems to have an autonomous existence, independent of his will and of his desire.” (“Wholeness & Implicit Order.)

What better way to reconnect with our environment than a walk in the woods?

The Japanese have a word, shinrin-yoku, which translates to “forest bathing,” and means “taking in the forest atmosphere.”

Developed in Japan during the 1980s, shinrin-yoku has become a cornerstone of preventative healthcare & healing in Japanese medicine.

Scientific experiments conducted in Japan reveal a host of health improvements that result from a simple 40 minute stroll in the woods:

  • Boosted immune system functioning, with an increase in the count of the body’s Natural Killer (NK) cells.
  • Reduced blood pressure
  • Reduced stress
  • Improved mood
  • Increased ability to focus, even in children with ADHD
  • Accelerated recovery from surgery or illness
  • Increased energy level
  • Improved sleep

Studies show that people who just looked at a forest view for 20 minutes had a 13% lower concentration of the stress hormone cortisol. (“The Healing Power of Trees.”)

Many trees give off organic compounds that support our “NK” (natural killer) cells, which are part of our immune system’s way of fighting cancer. (“The Science of Forest Therapy.”)

Trees have occupied a sacred place in human mythology for all of time. The Tree of Life appears in all of the world’s major religions, while The World Tree appears in a host of Indo-European & Native American cultures.

With its roots in the underworld, it’s trunk in our dimension, and its branches reaching up into the heavens, the World Tree is seen as being the axis that holds the cosmos together.

And trees indeed make our world possible.

Trees

I’ll leave you with a bit of tree wisdom from zen master Thich Nhat Hahh:

“I asked the leaf whether it was scared because it was autumn and the other leaves were falling. The leaf told me, ‘No. During the whole spring and summer I was very alive. I worked hard and helped nourish the tree, and much of me is in the tree.

“Please do not say that I am just this form, because the form of leaf is only a tiny part of me. I am the whole tree. I know that I am already inside the tree, and when I go back to the soil, I will continue to nourish the tree. That’s why I do not worry. As I leave this branch and float to the ground, I will wave to the tree and tell her, ‘I will see you again very soon.’”

    This corresponds with a program I watched on PBS. It made me realize that my enjoyment of the woods has a real basis in nature. Trees are a living part of our lives and necessary for our continued well being. Your tree photographs are stunning……so lovely.

  • Andrea Janda says:

    Beautifully sourced poetics and botanical lessons! I learned “crown shyness” —I love learning new words for how things grow and cooperate. Plus an underground pun for the mycorrhizal network, calling it the “wood wide web” Ha! Really enjoyed the read and inspiration . . .

    • Tai Woodville says:

      I’m thrilled you enjoyed it and got some nice takeaways! Thanks for letting me know. 🙂

      Your reader comment was part of my inspiration to zero in on this subject, which is so close to my heart. I was really happy to see reader interest in posts about the natural world and trees particularly. 🙂

      I’m a third generation tree lover and found all of this data simply fascinating as well.

      Here’s to forest bathing!

    Thank you so much for the article.
    I’ve been thinking about this exact topic and better ways to understand plant life for many years, but within the past 2-3 weeks in particular, these thoughts have been more prominent in my thinking.
    This article lines up perfectly.
    A lot of great information to continue my studies provided here too.

    Thanks again and all the best to you.

    • Tai Woodville says:

      I’m thrilled to hear it, Kz! It’s always my hope & intention that these posts can be synchronistic for readers.

      I’m also always glad to hear that nature is on your mind & heart. During these troubled planetary times, I truly believe that [re]connection to the natural world will be our salvation as a species.

      Thank you for telling me!
      I enjoyed researching for this article and learning these things as well. 🙂

      On on!

    Tai – you did it. You made me cry with joy over your lovely treatment of this subject close to my heart. Lately I have deepened my relationship with trees in a cedar grove close to me. I stand next to them and they bring me peace. But even better they send messengers (Ravens, Stellar Jays, Owls) and moments of serendipity in the forest I would have missed without my guide cedars.

    Later today I am going to write an article about the two baby cedar I have been watering during the drought here in Seattle. They bring me such joy to work with and the guardian trees have given me their approval. In that post I plan to link this wonderful post. So well timed!!

    Don’t stop writing. You have the gift of inspiring us to be our best and live in the spirit vs in the flesh.

    • Tai Woodville says:

      Dear Batgurrl,

      That makes me so happy. I am thrilled to have done your topic suggestion justice. I was overjoyed to hear multiple reader requests for posts about nature & the natural world. The forest around my house is a daily source of inspiration for me!

      Thank you for your meaningful words of support & encouragement!

      I also have great news, batgurrl…you won the comments raffle for my post a few months back asking what readers wanted to hear more about…I wrote you back on the comment thread, asking for your email so I could send you the prize: a book! 🙂 But I don’t think wordpress notified you and now the post is down. So I’d like to take this opportunity to also invite you to claim your prize. Just send your address to woodlandreveries@gmail.com. Or I can give you a digital gift card via email. Let me know! 🙂

      On on!

  • […] Trees are the silent fellows that we forget are beings too. Before I tell you my baby cedar story, I want to share a recent post by an internet friend of mine.  He writes a fabulous blog called Parallax. It touches subjects from man’s spiritual being to nature and this week “The Secret Lives of Trees”.  Here is a link to his post for your tree loving moment – Parallax […]
