L'arbre-mère est l'arbre le plus puissant et le plus vieux de la forêt, il est au centre d'un vaste réseau sous-terrain mêlant racines et champignons. Nourris et protégés par ce vaste réseau, de jeunes arbres vont se développer. Ils communiquent à l'aide de molécules similaires à des neurotransmetteurs et cet échange est le langage des arbres. Suzanne Simard a été une pionnière dans la compréhension de cette communication invisible et à offrir au monde une nouvelle vision de la nature. Une nature interconnectée, intelligente, sensible. La chercheuse nous raconte son cheminement jusqu'à cette incroyable découverte et comment le contact avec la nature lui a permis de surmonter les épreuves de la vie.
"Chercher à résoudre les mystères de ce qui contribue à faire avancer les forêts, et comment elles sont liées à la terre, au feu et à l'eau, a fait de moi une scientifique. J'ai observé la forêt et j'ai écouté. J'ai suivi ma curiosité là où elle m'a menée, je me suis intéressée aux histoires de ma famille et des gens, et j'ai appris des érudits. Etape par étape, énigme par énigme, j'ai investi tout ce que j'avais pour devenir détective, et découvrir ce qui est nécessaire à la réparation du monde naturel. Il ne s'agit pas d'un livre pour nous apprendre comment sauver les arbres. Il s'agit d'un livre pour nous apprendre comment les arbres pourraient nous sauver." Suzanne Simard

From 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--a moving, inspiring journey of discovery of how, as a child in love with the woods, the author came to believe that trees communicate with one another and the story of how she proved her seemingly laughable theory, uncovering their secrets as well, and in the process became a world-renowned scientist. Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; she''s been compared to Rachel Carson, hailed as a scientist who conveys complex, technical ideas in a way that is both dazzling and profound. Her work has influenced filmmakers (the Tree of Souls of James Cameron''s Avatar ) and her TED talks have been viewed by more than 10 million people worldwide. Now, in her first book, Simard brilliantly illuminates the fascinating and vital truth about trees--not simply the source of timber or pulp, but a complex, interdependent circle of life on which we rely for our existence--and at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain them. Born and raised in a logging family in the rainforests of British Columbia, Simard spent her days as a child cataloging the trees from the forest: as she came to love and respect them--and to wonder about them--she embarked on a journey of discovery, and struggle. She has spent a lifetime piecing together startling truths: that trees have perceptions, language, behaviors, memory, recognition of neighbors, reciprocity, healing capacities, and wisdom. Finding the Mother Tree is the fascinating story of how Simard overturned widely accepted beliefs to systematically prove, against all odds, that trees and plants in the forest are connected underground in an immense fungal web , (which Simard calls the Wood Wide Web). That the biggest, oldest trees, the mother trees , are the hubs of the network, with the fungal mycelia, the links. Simard not only invites us to understand trees in an entirely new way--she also makes clear what we can learn from the natural development of forests, in order to create a more civil and resilient society.
Finding the Mother Tree reminds us that the world is a web of stories, connecting us to one another. ... The interplay of personal narrative, scientific insights and the amazing revelations about the life of the forest make a compelling story... These are stories that the world needs to hear>
