Mythical Trees: The Woods Between Worlds
On the Quiet Consciousness of Trees, an Essay
It began with a single aspen—a tree I’d passed a hundred times without a second thought—and the sudden, vertiginous sense that it was not merely alive, but aware.
Let us ask a question that sits at the very edge of science and the paranormal. Are the trees talking to each other? Are the forests thinking? And if they are, what happens when we enter those forests?
I have spent the better part of two decades walking into the woods of the American West, initially as a kind of research, later as a reflex. I was a city-dweller by birth, an East Coast creature whose earliest wildernesses were the cracked sidewalks of Philadelphia and the fire escapes of Brooklyn. I moved through those early years inside a sealed bubble of selfhood, convinced that thinking happened exclusively within the calcium shell of the skull. The trees, if I noticed them at all, were scenery—elegant stagecraft for the human drama. Then I began writing a novel set in the high country, and decamped to Colorado for what I believed would be a few months of sensory fact-checking: the weight of dry air, the sound of pine needles underfoot. I did not expect the research to change the shape of my mind.
The shift arrived quietly, as real shifts do. I was hiking a familiar trail above Telluride, threading through a dense stand of aspens, their white bark scored with the dark, elliptical eyes that seem always to be watching. The light was the thin, buttery gold of late September. I stopped, not out of fatigue, but because something in the air felt different—thicker, charged, as if the space between me and the trees had become a held breath. I leaned against one of the trunks, palm flat on the cool, papery bark, and without quite meaning to, I found myself listening. Not for a sound, exactly, but for a presence. The aspen grove, I knew, was not a collection of individuals but a single organism, a vast underground network of roots and rhizomes, one of the largest living beings on earth. And standing there, touching it, I was overcome by the unnerving, irreducible conviction that the tree was not simply living, but experiencing.
This is, I realize, the kind of sentence that makes editors nervous and materialists reach for their copy of Daniel Dennett. We are trained to dismiss such moments as projection, the pathetic fallacy dressed up in hiking boots. But the feeling refused to fade, and so I did what a novelist does: I followed it into the library—and into the older, stranger libraries of the land itself.
Let me tell you about a tree named Pando. Pando is a quaking aspen in Utah. From above, it looks like a forest: 47,000 individual trees spread across 106 acres. But those 47,000 trees are not individuals. They are one organism. One massive interconnected root system sends up stem after stem, trunk after trunk. Every single tree in Pando is a clone; they share the same DNA, the same underground network. Pando is not just a tree. It is a superorganism, and it may be one of the oldest living things on Earth—perhaps 80,000 years old, perhaps older. That means Pando was already ancient when the last Ice Age ended, already ancient when the first humans crossed into North America. It has been growing, spreading, thinking—if trees can think—for longer than our entire species has been civilized.
“What we think of as fundamental reality is a world of conscious subjects, and physics describes the behavior of these subjects.”
— Philip Goff, Galileo’s Error: Foundations for a New Science of Consciousness
So here is the question, the one that followed me from the aspen groves of Colorado to the piñon-juniper scrub of northern New Mexico. Is Pando conscious? Is there a more penetrating mystery beneath this vast ancient network of roots and stems? The scientific evidence, it turns out, has been quietly accumulating for decades. In a recent article published by the Institute of Dendrology in Poland, researchers Tomasz Gryzwoziak, Ewelina Ratajak, and Hanna Fuchs summarized the current understanding: trees exchange information through chemical signals and electrical impulses in the underground mycorrhizal networks connecting their roots. They warn one another of potential threats, share resources with younger seedlings, and even cooperate across species. The forester Peter Wohlleben, in his book The Hidden Life of Trees, describes how trees recognize their own offspring, sending more sugars through the root network to their own seedlings than to strangers. They even appear to remember past events—droughts, insect infestations, fires—and adjust their behavior accordingly. The forest, in other words, is not a collection of isolated individuals. It is a community, a network, a kind of intelligence.
This is where the science bleeds into philosophy, specifically into the ancient and persistent idea of panpsychism—the view that consciousness, far from being a rare emergent property of complex brains, is a fundamental feature of all matter. The philosopher Philip Goff, in his book Galileo’s Error, argues precisely this: that consciousness is intrinsic to the physical world itself. Goff uses the example of a tree to illustrate this speculative leap. In a much-cited passage, he asks us to consider what it might be like to be a plant, lacking a brain and a central nervous system, and yet coordinating responses to light, gravity, moisture, and injury across its entire body. “Perhaps the tree has a very simple form of consciousness,” he suggests, “a blur of sensation that feels like something to be a tree, even if it doesn’t involve thought or self-awareness.” It is a radical idea, but then, so is the alternative: that the universe is, at its base, silent and dead, and that the flicker of experience you are having right now is a cosmic accident, a brief, inexplicable glitch in an otherwise vacant eternity.
I found myself drawn back to this idea, not as a neat intellectual puzzle, but as a visceral truth, one that my body had already accepted in that aspen grove before my mind could catch up. The novelist in me recognized the territory. Fiction, at its best, is a sustained act of empathy, a willingness to imagine consciousness into forms radically different from one’s own. I had spent years trying to inhabit the inner lives of invented people; why was I so resistant to the possibility of a much older, quieter inner life, one spread across the forest floor in a net of root and fungus?
And if we grant that possibility—if we allow, even as a thought experiment, that a forest might be a slow, distributed mind—then another question follows, the one that hovers at the paranormal edge of this inquiry: what happens when a human walks into that mind? What happens when we enter a space that is, in some sense, alive and watching? The world is full of places that answer that question with stories. Haunted forests, cursed woods, places where the trees themselves seem to reach out. Consider the Hoia-Baciu forest in Transylvania, called the Bermuda Triangle of Romania, where for decades visitors have reported strange things: phones and cameras that stop working, intense anxiety or unexplained euphoria, and trees twisted into spirals that defy the normal growth patterns of any known tree species. One guide hands visitors an EMF meter as they approach the clearing where a military technician photographed a UFO in 1968. In Japan, there is Aokigahara, the Sea of Trees, at the base of Mount Fuji, where compasses fail and the silence presses down like a weight. In England, Wistman’s Wood in Dartmoor, where moss drips so thickly from the tangled oaks that you can barely see the sky. In Germany, the Schwarzwald gave birth to the Brothers Grimm’s darkest tales. In Mexico, La Isla de las Muñecas, where doll parts hang from jungle branches. And in North America, the Long Trail in Vermont, where five people disappeared between 1945 and 1950 and only one body was ever found. Visitors report a weird, haunting energy that follows them through the woods.
“Perhaps the tree has a very simple form of consciousness, a blur of sensation that feels like something to be a tree, even if it doesn’t involve thought or self-awareness.”
— Philip Goff, Galileo’s Error
I do not have an answer. I am not sure anyone does. But I have walked through forests in the American West that made me feel, unmistakably, that I was being watched—not by an animal, not by a person, but by the architecture of the place itself. In Arches National Park, the junipers and pinyons grow out of cracked red rock with a tenacity that feels less botanical than spiritual, their roots seeking water in the dark with a patience that borders on the eternal. In the high desert of the Four Corners, I stood at the edge of Chaco Canyon at dusk, the ruins of an ancient civilization behind me and a sea of sage and scrub oak before me, and felt the weight of 80,000 years of root and stone pressing against the thin membrane of my own brief consciousness. In Taos, New Mexico, on the edge of the Sangre de Cristo Mountains, I walked through ponderosa groves where the vanilla scent of the bark and the deep, resonant silence created a cathedral of sensation—a space that felt less empty than crowded with presences I could not name. One speculative writer put the idea this way: what if consciousness were like gravity? The more mass there is, the stronger the gravity. What if consciousness were a group effort, where we all draw from a single collective source? If that is true, then a forest is not just many trees. It is one being, one mind—slow, ancient, patient. And we are walking through its thoughts.
These are not empirical claims, and I make no pretense otherwise. The nature writer is always tiptoeing along the fault line between observation and projection, between science and sacrament, between the material and the paranormal. But I have come to believe that the greater error is not in over-imagining the consciousness of the world, but in under-imagining it. The doctrine of human exceptionalism has left us strangely lonely, the sole bearers of mind in a universe of dead things. It has also, not incidentally, licensed a kind of violence: one does not agonize over the interior life of a two-by-four.
What if, instead, we allowed ourselves to credit these quiet encounters? Not as dogma, but as a working hypothesis, a way of moving through the world with increased humility and attention. The forests I have walked, from the San Juans to the La Sals, from the wet shadow of the Olympics to the redrock canyons of Utah, all seem to hum with the same question: What if you are not the only ones?
I do not know the answer. But I have learned to live inside the question, and it has made the world larger, stranger, and infinitely more companionable. The trees are talking to each other—science has proven that. They are warning each other of threats. They are sharing resources. They are cooperating across species. They may even be remembering. I am a man who has spent much of his life in cities, and I expect I will die in one. The concrete will remain my primary geology. But the forest is where I learned to listen, and what I am learning, slowly, is that listening may be the most honest form of thought. The trees are not shouting to be heard. They are simply there, conducting their slow, green consciousness, patient as the turning of continents. And if you stand still enough, long enough, you can almost hear the shape of what they’re saying. The next time you walk through a forest, especially an old one, a deep one, a place where the sunlight barely touches the ground, remember that. You are not alone. You are walking through a network, a community, a mind, perhaps, one that has been growing, thinking, dreaming for longer than your entire civilization has existed. And if you feel something watching you, maybe you are right.
