"Intelligent Trees" centres around the groundbreaking scientific discoveries that Professor Dr. Suzanne Simard has been making in the Canadian Wilderness since the 1990s and that seem to be valid for all natural forests around the world! The German forester Peter Wohlleben has observed that the trees in his district communicate with each other, care lovingly for their offspring and for their old and sickly (tree-)neighbors. These observation appear to be supported by scientists like Dr. Simard. And he wrote a bestseller about it, which was enthusiastically embraced by nature lovers but fiercely challenged by forest practitioners. "Intelligent Trees" shows research from the University of British Columbia that supports most of his claims. This documentary features the scientific detective work needed to understand the interactions between trees and explores what consequences could and should this knowledge have for our use of our forests.
