From New York Times bestselling author Doug Tallamy, a revealing look at one of the most essential members of the plant kingdom. Oaks support more life forms and interactions than any other tree genus in North America, sustaining everything from acorn-collecting woodpeckers to caterpillars that dazzle like jewels. Tallamy uncovers the busy hub of life in an oak tree through the seasons, and once again turns the nature that surrounds us into a source of wonder and discovery.
