The Wild Trees: A Story of Passion and Daring is a non-fiction book by Richard Preston about California's coastal redwoods (Sequoia sempervirens) and the recreational climbers who climbed them. It is a narrative-style collection of stories from climbers who pioneered redwood climbing, including botanist Steve Sillett, lichenologist Marie Antoine, and Michael Taylor. They inadvertently discovered a thriving ecosystem hidden among the tree tops, 60–90 meters (200–300 ft) above, of redwood lattices, berry bushes, bonsai trees, epiphytes, lichens, voles, and salamanders.
