This book explains what a tree is, how trees are classified, and how to keep a record of the trees you have seen. Packed with over 1,000 full-colour photographs of more than 500 trees this book cuts through the complicated identification process to enable you to recognize a species instantly. The book provides a visual key that shows the differences between conifers, broadleaves, and palms, identifies each genus by leaf type, and guides you to the correct species entry. Every entry combines a precise description with annotated photographs to highlight the tree's chief characteristics and distinguishing features, and a full-colour illustration showing the spread, height, and leaf persistence of the species. A concise glossary defines technical and scientific terms.
