Brian Cox and Robin Ince are joined by Ted Lasso's Brendan Hunt, Professor of forest ecology and author of "The Mother Tree", Suzanne Simard and botanist Mark Spencer to discover how trees and plants communicate and what they are saying. Suzanne's incredible discovery that trees form a wood wide web of communication has changed our entire understanding of forests and how they work. With the help of amazing fungi, this incredible network of communication allows the trees and plants in a forest to pass information backwards and forwards to help protect themselves against predators and optimize resource. Incredibly, this could even be viewed as a form of intelligence. Brian and Robin find out how this should change the way we look at all plants, and in particular how we manage our forests and discover some of the secrets of those whispering trees.
