With the help of beautifully detailed illustrations and photographs, this book leads us on an intimate tour of the oak tree s dense root system, its lush canopy, the trunk s complex circulatory system, its reproductive processes, and its unique and densely-packed seed the acorn. We learn the importance of the oak to combat air pollution, and supply building materials for people, as well as provide a food supply for many woodland animals.
