Tree scientist Harriet Rix reveals the inventive and astonishing ways trees learned to shape the natural world.

Rix ranges from the earliest prehistoric forests to today’s trees to show trees using fire as a reproductive tool, harnessing large mammals to spread their seed but poisoning less useful smaller mammals, and splitting rock to create fertile ground. Rix says trees manipulate fundamental elements including plants, animals, bacteria, fungi and even humans to get what they need. Rix encourages us to see trees in a new way, not as victims but as agents of change in an ecological narrative.

Rix is a tree science consultant and writer formerly based at the Tree Council. She is a former secretary of Hedgelink and is a trustee of the Iraqi environmental charity Hasar.
