Many people know how to identify trees by their leaves, but what about when those leaves have fallen or are out of reach? With detailed information and illustrations covering each phase of a tree's lifecycle, this guidebook explains how to identify trees by their bark alone. Chapters on the structure and ecology of tree bark, descriptions of bark appearance, an easy-to-use identification key, and supplemental information on non-bark characteristics - all enhanced by over 450 photographs, illustrations, and maps - will show how to distinguish the textures, shapes, and colors of bark to recognize various tree species, and also understand why these traits evolved.
