These guides provide simplified reference that allows easy identification of species at a glance. Each pocket-sized folding guide features up to 150 species, and most contain a map pointing to prominent sanctuaries and outstanding natural attractions. Pocket Naturalists are lightweight, laminated for durability, and water- and dirt-resistant.
