FEW scientists make much impact with their PhD thesis, but, in 1997, Suzanne Simard did just that. She had discovered that forest trees share and trade food via fungal networks that connect their roots. Her research on "the wood wide web" made the cover of Nature. What was then a challenge to orthodox ideas is today widely accepted. But Simard and her colleagues continue to challenge our preconceptions of how plants interact. Among other things, their research shows that the wood wide web is like a brain and can communicate information throughout the entire forest, that trees recognise their offspring and nurture them and that lessons learned from past experiences can be transmitted from old trees to young ones. Simard calls herself a "forest detective". Her childhood was spent in the woods of British Columbia, Canada, where her family had made a living as foresters for generations. As a young woman, she joined the family profession, but soon realised that modern forestry practices were threatening the survival of the ecosystem she loved. She knew that, when logged with a lighter touch, forests can heal themselves, and she set out to discover how they are so naturally resilient. Along the way, her concern for the future of forests sparked an intense curiosity about what makes them tick.
