I<\/span>n 2018, the ecologist and writer Suzanne Simard was conducting research in the forested Caribou Mountains of western Canada when a thunderstorm rolled in. She was with her two teenage daughters and her close friend and colleague, Jean Roach. They saw flashes of lightning, heard a loud rumble and then they smelled smoke. They were forced to run the half kilometre back to Simard\u2019s truck as the trees behind them caught alight and the air grew thick. As they ran, animals burst out of the forest: a deer, a rabbit, a grey wolf. They reached the truck with no time to spare, all four of them covered in soot and dirt. Overhead, helicopters began circling the orange-black air, dropping water on the flames below.<\/p>\n Wildfires have become an ever bigger problem in Canada. The 2018 wildfires were the biggest in British Columbia\u2019s history, but this record was broken in 2021, and then again in 2023, when fires consumed an area three times the size of the Canadian province of Nova Scotia and the smoke travelled as far as New York City. The cause is not only global heating, which has brought hotter, dryer summers, but also the changing makeup of the forest. When logging companies clear forest, they replant it with fast-growing conifer species, but these trees are much more flammable than Canada\u2019s diverse, native forest.<\/p>\n The country\u2019s forests are so huge that for decades policymakers assumed that human activity would make little impact. \u201cThe rationale was that it will all come out in the wash: the trees will recover, the forests will grow back, and we\u2019ll all be fine,\u201d Simard says, speaking on a video call from Vancouver. But deforested areas do not fully recover, and thanks to logging, the wildfires and a devastating pine beetle outbreak, Canada\u2019s forests, once a vast carbon sink, have since 2001 been a net emitter of carbon.<\/p>\n For four decades, Simard, a professor of forest ecology at the University of British Columbia in Vancouver, has been trying to convince foresters and policymakers that it doesn\u2019t have to be this way. \u201cWhat we\u2019re doing by taking down forests is we\u2019re undercutting our ability to solve, and to provide natural solutions to, climate change,\u201d she says. Billions of dollars are being invested in carbon capture and storage technology, \u201cbut we actually have highly evolved organisms like trees and plants and algae that do this very thing much more effectively than anything we can possibly create ourselves. And yet, we\u2019re cutting these creatures down.\u201d<\/p>\n Her use of \u201ccreatures\u201d is not a slip. Simard\u2019s research, outlined in her bestselling 2021 book, Finding the Mother Tree, has suggested that trees are perceptive, collaborative, able to communicate with one another and to recognise kin. While scientists have traditionally viewed forests as a collection of individual trees competing for resources, Simard argues that they are better thought of as complex, interdependent communities, connected by an underground network of fungi known as mycorrhiza, through which nutrients are exchanged.<\/p>\n She names the oldest, biggest, most connected trees the \u201cmother trees\u201d (although trees are both male and female), to reflect their role in nurturing the surrounding forest. \u201cI came up with the idea with a group of my students and colleagues in a bar, actually,\u201d she says. \u201cEveryone has a mother. Everybody knows they were nurtured and cared for and that they needed a boost up.\u201d It turned out to be a better metaphor than she imagined, she says, because many cultures already speak of mother trees.<\/p>\n double quotation markIn this period of\u00a0rapid climate change we need to be\u00a0creative \u2013 we need to break out of the scientific mould<\/p>\n Simard is 65, with bobbed, grey-blond hair and a thick Canadian accent, all soft vowels and generous, round \u201cr\u201ds. She is friendly but seems guarded on our call, and she keeps her video background blurred. One senses she\u2019d be much more comfortable trampling through the forest, sharing a beer on the bed of a pickup truck or, frankly, even hiding up a tree from a territorial mama grizzly \u2013 something she has actually had to do, bears being a common field hazard.<\/p>\n She describes herself as a \u201cperson of the forest\u201d, having grown up in the Monashee Mountains of British Columbia, where her grandfathers and uncles worked as loggers, and where you can find a creek and a mountain named after her family. Simard followed her relatives into the industry by studying forest management at the University of British Columbia and taking seasonal work at a logging company in the early 1980s, when she was the only woman on staff. Later, she completed a master\u2019s and a PhD in forest ecology at Oregon State University while working for the Canadian forest service as a research scientist.<\/p>\n Then, as now, logging companies clear-cut swathes of forest and replanted them with a fast-growing, single species of tree. They used herbicides to kill other plants that intruded on replanted forest, so that the conifers would not be outcompeted. Simard noticed, however, that replanted forests were often sickly. She observed that, contrary to received wisdom, seedlings seemed to fare better when they grew alongside other plants, and she came to suspect that the mycorrhiza that colonised the soil in diverse forests played a role.<\/p>\n <\/span>Suzanne Simard <\/span> Photograph: Alana Paterson\/The Guardian<\/p>\n Simard recorded that up to 10% of newly planted Douglas firs would get sick and die whenever nearby aspen or paper birch were removed. As part of her doctorate thesis, she demonstrated that fir and birch trees, which often grow together in the wild, trade nutrients. When a birch tree shades a fir, it transfers more carbon to it, via mycorrhiza. When the birch tree loses its leaves in autumn, the flow of carbon is reversed. In 1997, Simard published a landmark paper in the scientific journal Nature, outlining her findings. Nature ran it as a cover story, under the catchy title \u201cThe wood\u00a0wide web\u201d, referencing the underground network\u00a0of mycorrhiza that enables trees to exchange nutrients. To be published in such a prestigious journal was a remarkable achievement for a forest service scientist, and the paper garnered international media attention because it suggested a new way of understanding how forests work, and what trees are: intelligent, perceptive beings. In 2002, she left the forest service for full-time academia.<\/p>\n While foresters have traditionally adopted the \u201cmasculine\u201d lens of dominance and competition, Simard says her research helped introduce the missing \u201cfeminine perspective\u201d. \u201cThe forest has got all of these connections and relationships, which women understand really well, and we nurture and honour these things. Men are sometimes, you know, blind to that.\u201d She says that while the scientific community has often had a \u201charder time\u201d absorbing her ideas, her work aligns with indigenous wisdom on how forests work and tends to make intuitive sense to lay people, too. People often write to her to tell her how her work resonates with them because, \u201cthey understood from their hearts that of course forests are social places \u2026 so it\u2019s their intuition, their deep wisdom,\u201d she says.<\/p>\n In 2016, Simard gave a TED Talk, \u201cHow trees talk to each other\u201d, that has been viewed more than 8m times online. Her research turned her into a cult figure, inspiring a character in Richard Powers\u2019s Pulitzer prize-winning 2018 novel, The Overstory, and paving the way for other popular science books such as Peter Wohlleben\u2019s The Hidden Life of Trees and Merlin Sheldrake\u2019s Entangled Life.<\/p>\n But, after the publication of The Mother Tree, Simard\u2019s work was met with forceful scientific backlash. This was not limited to critiques in academic journals. One critic wrote a letter to her university accusing her of lacking scientific integrity, and emailed newspapers and magazines asking them to remove profiles of her. This seems to go beyond the realm of scientists debating the research, I say. \u201cYes, I agree,\u201d Simard says. \u201cI don\u2019t know how unusual that kind of backlash is. I think it happens, and it\u2019s kind of unfortunate. But I look back, and I think history repeats itself.\u201d She cites the resistance faced by the primatologist Jane Goodall, because she named the chimps she studied, and James Lovelock, who first proposed the Gaia hypothesis, the idea that the Earth is a self-regulating system. Backlashes happen, she says, \u201cwhen you have an idea that is a little revolutionary, that is not following the mainstream, that threatens the structure of the scientific method\u201d.<\/p>\n Simard\u2019s initial reaction was to retreat. She started keeping her camera off in Zoom calls. \u201cIt was really hard, that whole period,\u201d she says. \u201cBecause my training is in science. My degrees are in science. My job is about science \u2026 It\u2019s so hurtful because it\u2019s your peers \u2013 it\u2019s a rejection.\u201d The forest ecology community is small, and some of those publicly criticising her work were former collaborators and co-authors. Did it seem personal? \u201cI don\u2019t know the answer to that question. You could ask them, but I hadn\u2019t been in contact with them for a while, so I don\u2019t know,\u201d she says.<\/p>\n There are specific points of contention, over questions such as whether fungi are the prime way that nutrients pass between plants, or whether Simard underplays the role of competition in forests, and she sends me a paper in which she responds to these points. An overarching theme, however, is that there still isn\u2019t enough evidence for Simard\u2019s assertions. \u201cThat\u2019s such a common refrain in science, and who can argue with that?\u201d<\/p>\n Simard says she sometimes feels straitjacketed by science, which moves too slowly to meet the urgency of the climate crisis. \u201cThe scientific methodology has a lot of rules and sometimes it can feel suffocating,\u201d she says, with a dry laugh. \u201cWhen it dampens your curiosity, when it requires you to be less artistic than you might otherwise be. I could see the limitations of science. In this period of rapid climate change we need to be innovative, we need to be creative, we need to have all hands on deck and sometimes we need to break out of the scientific mould \u2026 I wanted to get out and try things and not be so worried. If I need 50 years of research to figure out how to restore this forest so that it\u2019s got good structural diversity, I may not get there in\u00a0time.\u201d<\/p>\n Simard is also critical of science\u2019s tendency to break down questions into their smallest parts, to focus narrowly on cause and effect, which she says makes it harder to study relationships and systems. \u201cIf I take forestry, for example, for a long time we studied: how do we grow bigger trees? And we got so focused on growing bigger trees that we didn\u2019t think about the water and the plants and the animals and the impacts on them,\u201d she says. \u201cSo we made a mistake by losing the whole picture. We were smart but not wise.\u201d She takes inspiration from Indigenous wisdom, which has long recognised the interconnectedness of the forest and honed regenerative forestry practices over centuries of close observation of nature.<\/p>\n Since 2015, Simard has been running the Mother Tree Project, a huge national study that argues that scientists have massively underestimated the environmental harm of clear-cutting and explores more sustainable ways to log: for example, when foresters leave behind some of the biggest trees in the forest \u2013 the mother trees \u2013 and do not fully clear the land, they enable the forest to regenerate more effectively.<\/p>\n In her latest book, When the Forest Breathes, as in her first, Simard blends science and memoir, a stylistic choice that reflects how closely her personal life and the forest entwine. She writes not only about the Mother Tree Project, but about recovering from breast cancer \u2013 having been diagnosed in 2012 \u2013 and watching her daughters grow up and leave home. \u201cThere is no way to understand how something grows without also understanding how it dies,\u201d she observes at the beginning of the book, and she writes of her grief at losing a young colleague, the researcher Amanda Asay, who died in a skiing accident in 2022, and her mother who, a few months later, sought medical assistance to die, after suffering from dementia and other health problems. \u201cAlthough it was extremely difficult, I respected that my mum wanted to have a say, agency in her whole cycle of life,\u201d she says. She is proud that Canada has taken a \u201cprogressive\u201d stance by legalising assisted dying.<\/p>\n Simard feels buoyed up by the public pressure on the Canadian government to improve forestry practices, but she believes that while it wants to \u201cdo the right thing\u201d, the geopolitical tensions between the US and Canada are pulling the government in the opposite direction. \u201cOne of the consequences of moving away from the US towards greater self-reliance is increasing resource extraction,\u201d she notes.<\/p>\n While south of the border, the Trump administration is rolling back environmental protections and promoting climate change denialism, Simard believes Canadians\u2019 lives have already been so dramatically affected by the changing weather that they are more likely to believe the science. \u201cClimate change is all around us. People are literally trying to protect their lives and property from wildfire, it\u2019s been building over the past decade or so. And so, it\u2019s real, right? We can feel it in our everyday lives.\u201d Instead, she believes the bigger challenge in Canada is combating a feeling of defeatism. \u201cI hope when people read this book, they come to feel agency in motivating change.\u201d<\/p>\n She wonders if this new book will provoke a renewed backlash but says she feels better equipped to cope if it does. \u201cThen, I was so taken aback, I was so surprised,\u201d she says. She hopes this time she won\u2019t be quite as hurt. It helps, she says, to remember that her work has not been \u201cuniversally rejected\u201d, and that many people find it helpful and illuminating.<\/p>\n In June, after she finishes her book tour, Simard plans to take a sabbatical from teaching to spend more time in the woods and mountains that surround her home town of Nelson, British Columbia. One gets the impression, when she describes her upcoming travel schedule, that returning to her home turf will be a relief. She lives alone now that her daughters are at university, in Vancouver and Corvallis, Oregon. Her partner, Mary, also lives in Oregon. \u201cWe\u2019re all within an eight-hour drive \u2013 in Canadian terms, eight hours is not that much,\u201d she says.<\/p>\n It has been unusually warm in the western US this year. \u201cIn my little town, where we usually get feet of snow through winter, we\u2019ve had almost none. It\u2019s very worrisome,\u201d she says. Like many of her neighbours, she\u2019s already thinking about the next wildfire.<\/p>\n When the Forest Breathes by Suzanne Simard will be published by Allen Lane on 31 March.
