Suzanne Simard is one of the world's leading forest ecologist who forever changed how people view trees and their connections to one another and to other living things in the forest. Her new book is "Finding the Mother Tree: Discovering the Wisdom of the Forest."
Simard brings us into her world, the intimate world of the trees, in which she illuminates the fascinating and vital truths - that trees are not simply the source of timber or pulp, but are a complex, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own.
