Dr. Suzanne Simard is changing how people view trees and their connections to one another and to other living things in the forest. In this inspiring and accessible talk, Dr. Simard helps audiences understand just how vital trees are—to each other and to humans. By bringing us into the intimate world of trees, Dr. Simard illuminates how trees are not simply the source of timber or pulp, but form complex, interdependent circles of life. As Dr. Simard illuminates for us, forests are social, cooperative creatures connected via underground networks through which trees communicate their vitality and vulnerabilities in ways not that different from our own. Dr. Simard’s groundbreaking research explores how trees, living side by side for hundreds of years, evolve, perceive one another, learn and adapt their behaviors, and remember the past. In helping us understand these complex ecosystems, Dr. Simard emphasizes the critical need to rethink our relationship with our natural world so we can begin to heal our climate.
