Trees, the largest of all living things, are vital components of the landscape and have been exploited by humans since the beginnings of our history. They cover huge areas of the globe, from the rainforests of the central tropics to the conifer forests of the subarctic, and from high up mountains right down to the seashore. Roland Ennos sheds light on trees by asking simple questions about them. How did trees evolve? How do they stand up? Why are there so many different types? How and why do we exploit them? All these questions, and more are answered in this illustrated book, which aims to provide a fascinating insight into the biology of these magnificent plants.
