262. Suzanne Simard with Lynda Mapes: When the Forest Breathes

 Forest ecologist Suzanne Simard has long been fascinated by the sharing of natural knowledge. From the interconnected root systems she studied in her book *Finding the Mother Tree* to her ongoing work as an educator, Simard has learned to see the importance of cooperative efforts to share resources and knowledge. Joined in conversation by Seattle-based nature journalist Lynda Mapes, Simard expands these connections into a considerate exploration of the elaborate cycles of forest ecosystems, the challenges they currently face, and the intergenerational value they can provide through her new book *When the Forest Breathes: Renewal and Resilience in the Natural World*. Raised in a family of loggers committed to sensible forest stewardship, Simard has watched as modern practices and timber companies have left forests vulnerable to damage and depletion. In her research, Simard explores the finely honed cycles of regeneration forests inherently use to maintain themselves. From mushrooms breaking down logs to dying elder trees passing their genetic knowledge to younger growth, *When the Forest Breathes* presents these cycles as a key component in the protection and preservation of our forests. Working closely with Indigenous communities and the models of responsible forestry they've upheld over time, Simard examines the damage caused by industrialization and wide-scale human intervention– particularly the impact on the overstory's mother trees that are responsible for sharing intergenerational wisdom and supporting new growth. As Simard seeks to understand the importance of stewardship and how older lives can facilitate the conditions for new growth to flourish, she considers similar patterns of loss and regeneration in her own life. Savoring her final days with her ailing mother and watching her daughters grow into adults, Simard draws thoughtful parallels around what caretaking looks like within the forest and within our own communities. Animated by wonder and the urge to honor the tools that trees have honed over generations, *When the Forest Breathes* aims to use the lessons of the natural world to encourage paths of adaptability, resilience, cooperation, and valuing our forests. **Dr. Suzanne Simard** is the *New York Times* bestselling author of *Finding the Mother Tree.* She is a Professor of Forest Ecology at the University of British Columbia, where she leads The Mother Tree Project and co-directs the Belowground Ecosystem Group. Dr. Simard has earned a global reputation for pioneering research on tree connectivity and communication and the productivity, health, and biodiversity of forests. Her work has been published widely, with over 170 scientific articles in peer-reviewed journals, including Nature, Ecology, and Global Biology, and she has co-authored the book Climate Change and Variability. Her research has been communicated broadly through three TED Talks, TED Experiences, as well as articles and interviews in *The New Yorker, National Geographic, NPR, CNN,* and many more. She lives with her family in the mountains around Nelson, British Columbia. **Lynda Mapes** is a journalist, nature writer, and the author of six books on the natural and cultural history of the Pacific Northwest. Her previous publications include *The Trees are Speaking* and *Orca: Shared Waters Shared Home*. She was previously an environment reporter for the *Seattle Times,* focusing on nature, natural history, Native cultures and governments, and Pacific Northwest environmental news, where she was named a finalist for a team award for the Pulitzer Prize for Local Reporting in 2025.
