A Field Guide to Trees and Shrubs : Northeastern and north-central United States and southeastern and south-central Canada

Summary: the one
Review: As a wetland delineator in PA, this book proves invaluable for field identification of trees, shrubs, and vines. Especially useful is are the keys for identification of these plants in winter when leaves and fruiting bodies are non-existant. I have several other tree books for reference, but they rarely are worth carting along in the field now that I have this book. I highly recommend it.

Summary: the one
Review: No mere Peterson field guide, this scholarly work is a concise encyclopedia of all the trees native to the northeastern United States, with descriptions that can truly be used to tell them apart (a unique feat). Belongs in the backpack of any hiker who wants to learn trees. Fits in a half-gallon Ziploc. Remember you need a magnifying glass and a sharp knife to use the book properly.

Summary: Definitive work for identification
Review: Petrides' work is the most accurate I have found in tree identification. Color pictures are no substitute for a close-up examination of the stems, leaves and fruit of trees and shrubs. It is considered the definitive source for the John Burroughs Naturalist Award bestowed by the Buckeye Council of the Boy Scouts of America only upon those capable of sight identification of approximately 600 trees, shrubs and wildflowers.
