In this large-format guide, Gibbons discusses the parts of a tree and their functions, the growth of trees, and the different types of trees. She introduces topics such as photosynthesis and the meaning of terms such as phloem and cambium. In the almost wordless section on identification, the shapes of 15 different trees are shown alongside close-ups of their leaves and bark. The book closes with a discussion of how trees are useful to people, animals, and the environment, and directions for making a tree identification book. The bright watercolor illustrations show cheerful children and adults observing, planting, using, and enjoying many kinds of trees. In this simple, informative book, Gibbons provides a basic guide that is sure to please parents and teachers as well as children. Carolyn Phelan
