The Sibley Guide to Trees
David Allen Sibley, the preeminent bird-guide author and illustrator, now applies his formidable skills of identification and illustration to the trees of North America. Monumental in scope but small enough to take into the field, The Sibley Guide to Trees is an astonishingly elegant guide to a complex subject. It condenses a huge amount of information about tree identification more than has ever been collected in a single book into a logical, accessible, easy-to-use format. With more than 4,100 meticulous, exquisitely detailed paintings, the Guide highlights the often subtle similarities and distinctions between more than 600 tree species native trees as well as many introduced species. No other guide has ever made field identification so clear.
