Trees are not passive components of ecosystems. They are active system-builders that regulate water, carbon, climate, and biological relationships throughout Earth’s living world.
In this course, Jim Laurie examines the intelligence of trees – how trees sense, respond, and adapt through symbiotic relationships with fungi, microbes, insects, and animals, including humans. Drawing on contemporary ecological science and two companion texts—The Genius of Trees by Harriet Rix and Trees: An Illustrated Celebration by Kelsey Oseid—this course explores how trees drive transpiration and cloud formation, stabilize atmospheric chemistry and carbon sequestration, and generate large-scale cooling through the biotic pump.
Rather than treating intelligence as a uniquely human trait, the course reframes it as an emergent property of living systems, expressed through physiological feedback, cooperation, and adaptive symbiosis. These insights offer a scientific foundation to deepen your understanding of how trees and living ecosystems work—and how protecting and restoring biodiversity in nature can reset the path of humanity towards a livable future.
