The Hidden Life of Trees

The Hidden Life of Trees: What They Feel, How They Communicate

by Peter Wohlleben

An absorbing, leisurely read, about how trees grow and communicate. If you enjoy a walk in the woods of area forest preserves or the Morton Arboretum, you may enjoy spending time with German forester Peter Wohlleben. I was interested to learn that trees, even of different species, can communicate with each other through scent and chemical signals sent through the fungal network around their roots. They can send signals of attacks by insect pests or herbivores, and even share sugar when another tree is stressed or injured. They also compete for sunlight and space, migrate (very slowly) when the climate changes, react to storms, drought, and injuries, and take risks deciding when it’s best to grow taller or shed their leaves. The likelihood of a single seedling growing up to be a mature tree is very small, but it can be supported by its parent tree as it grows. Urban trees have more challenges, but still manage to communicate, though they aren’t likely to live hundreds of years like a beech or oak tree in a forest. Wohlleben even has a 500-year plan to create thriving forests, which may be aided by getting his many readers to think about and see trees differently.
