Guide Review - What Tree is That?

What Tree Is That? is one of the best weather-resistant, pocket-sized tree identification manuals with a key available for the most common trees of North America. One hundred and thirty six illustrated pages are crammed full of tips that help in identifying North America's most common native trees. This Arbor Day Foundation tree guide provides every included tree's leaf, fruit, twig and bark description along with great illustrations. Excellent clues are included that assist in making the final identification. This key is dichotomous. You determine the best answer of two questions until identification. Many times you can skip the key if you review the leaf illustrations and have some knowledge of individual tree species.
