When the Forest Breathes

Renewal and Resilience in the Natural World

De: Suzanne Simard

The trailblazing scientist who pioneered the concept of sophisticated communication between trees returns with a book that places nature’s own cycles of renewal at the center of a powerful vision for the future of our forests

With her bestselling book Finding the Mother Tree, forest ecologist Suzanne Simard introduced the world to the profound intelligence and interconnectedness of trees. Now, with When the Forest Breathes, she uncovers the ways that nature’s deep-rooted cycles of renewal can ensure the longevity of threatened ecosystems.

Raised in a family of loggers committed to sensible forest stewardship, Simard has watched as timber companies leave forests at higher risk for wildfires, water crises, and plant and animal extinction. But her research has the potential to chart a new course. The forest, she reveals, is a symphony of finely honed cycles of regeneration—from mushrooms breaking down logs to dying elder trees passing their genetic knowledge to younger ones—that hold the key to protecting our forests. Working closely with local Indigenous communities, whose models of responsible forestry have been largely dismissed, Simard examines how human interventions—particularly destruction of the overstory's mother trees—endanger new growth and longevity. If we can honor the tools that trees have honed for sharing intergenerational wisdom, she argues, we can protect these sacred places for many years to come.

As she considers how older living things facilitate the conditions for new growth to flourish, Simard faces parallel rhythms of loss and regeneration in her own life, watching her two daughters grow into adults and savoring her final days with her ailing mother. Animated by wonder for our forests and the intricate practices of caretaking that have long sustained them, When the Forest Breathes is a vital reminder of all the natural world has to teach us about adaptability, resilience, and community.

Reseñas de la Crítica

“A masterclass on the inner workings of forests—a lush glimpse at the symphonic mutualisms and intergenerational cascades that sustain life at every scale. Simard, one of the boundary-pushing scientists of our time, is also a resplendent storyteller. Through her, new threads of connection between Indigenous knowledge and Western science are formed. The experiments and ideas in When the Forest Breathes are quietly revolutionary. This is science as an act of love for the world.”
