Perhaps it is only logical and natural that the man who would devote many years and much artistry to birds would lavish equal attention on the trees where they reside. In layout and spirit, The Sibley Guide to Trees is the perfect match to David Allen Sibley's guide to birds. In its pages, he presents 600 North American tree species with his incomparable paintings, which are models of both detail and elegant clarity. Species are arranged taxonomically (i.e., by families and genera), not (as in most other guides) by leaf shape, thus offering readers an easier path to true understanding of the plant world. The Mercedes-Benz of tree guides; an instant classic.
