Trees are familiar components of many landscapes and have been vital in determining the ecology of our planet as well as the development of human cultures and communities. Yet how much do we really understand about how they work? This updated and revised edition provides a comprehensive introduction to all aspects of tree biology and ecology and presents the state-of-the-art discoveries in this area. The wonders and mysteries of trees are explored throughout the book and questions such as why leaves turn spectacular colours in the autumn, how water reaches the top of the tallest trees, or why the study of genetics has caused so many name changes in trees are all brilliantly answered. Written with a non-technical approach, this book will be a valuable source of reference for students and those with a less formal interest in this fascinating group of plants.
