And so I grew up there, my great grandfather, my grandfather, my dad and uncles were all horse loggers, and seeing how, you know, how to live in forests and make a living out of it without actually destroying the forest.ĭOERING: It sounds like understanding the forest being in the forest is in your blood. birches, it's very, very species diverse forest for the Pacific Northwest. So you know, I live in a province of forests in British Columbia, and there's so many different kinds, but I grew up in what are called the inland rain forests, beautiful, huge trees, cedars, and hemlocks, Bruce's larches. Where do you trace your connection with the forest back to? It's good to be here.ĭOERING: So, you just really have this way of looking at a forest and seeing so much more than I think most of us ever do. She teaches forest ecology at the University of British Columbia and joins me now. In her new book, “Finding the Mother Tree: Discovering the Wisdom of the Forest,” ecologist Suzanne Simard reveals what she’s discovered about these connections through decades of experiments with trees. The soil fungi called mycorrhiza create a complex “wood wide web.” It’s how ancient “Mother trees” and other plants can send nutrients and warning signals back and forth for the benefit of the entire forest ecosystem. There, an intricate web of roots, insects, fungi, and bacteria is teeming with life, and contains twice as much carbon as the trees themselves. Ancient forests thousands of years old, are awe-inspiring but no less impressive is the complicated network of life beneath the soil that we can’t see. This process is experimental and the keywords may be updated as the learning algorithm improves.DOERING: Walking in an old growth forest like the towering Sequoias in California can be something akin to a spiritual experience for some. These keywords were added by machine and not by the authors. Real soil does not exist without such a living community. As our initially skinless planet aged, an outer jacket of soil eventually became a reality owing to the essential actions of macroscopic life. Although some microorganisms, mainly bacteria, were thriving at that time, their contribution to the transformation of the weathered inorganic rocky material was negligible and has not been documented. Without the contributing actions of these organisms, a soil cannot exist. Before this time, only weathering fragments and remnants from rocks – stones, gravels, sands, and even clays – scattered across continental surfaces, completely void of any action by living macroorganisms. During this period, various kinds of proto-soils gradually began to uniquely develop and slowly appear at diverse locations. It was the time of Earth’s adolescence and certainly not immediately after the birth of our planet.

This migration was happening roughly 500 million years ago – maybe even a little bit earlier.

The soil, or the Earth’s skin as we used to say, started its existence when macroscopic life was moving from oceans to the mainland, to the surface of continents and islands.

Hearing the parable about Earth’s skin, others may deduce that soil and the Earth were created simultaneously. First, this comparison is not exact because we mammals are born with skin, have it at the beginning of our existence, and continue to have skin throughout our lives even if it is not in perfect condition upon death. When we have now more space and the reader has more time, we can afford the luxury of going into some details. We have mentioned earlier in the introductory chapter that recent soil scientists like to say in their scientific jargon that the soil is a sort of skin to our planet Earth.
