What Tree Is That?: A Guide to the More Common Trees Found in North America

The Arbor Day Foundation's What Tree Is That? is a unique field guide that uses a step-by-step approach to identify common trees of the United States and Canada. The fully illustrated, 164-page book helps readers recognize more than 250 varieties based on trunk bark, leaf margins and textures, pods, nuts, and the arrangement of leaves on twigs.

Focusing on specific characteristics, this easy-to-use field guide poses a series of questions paired with botanical illustrations to help classify the tree in question. Created by the world's largest nonprofit devoted to trees and the environment, this guide offers a proven classification method for people of all ages--from youth to adult, amateur to professional.

The guide is a practical educational tool containing both the common and scientific names of trees and measurements in both inches and centimeters. Equipped with a durable, water-resistant cover, this 8½ x 4-inch companion guide slips easily into a pocket for easy reference on hikes.

The Arbor Day Foundation is a nonprofit environmental and education organization of nearly one million members, with a mission of inspiring people to plant, nurture, and celebrate trees. It has

• helped plant nearly 10 million trees in 2007.
• helped replant more than 10 million trees in national forests in the last ten years.
• helped preserve over 48,000 acres of rain forest.

Karina I. Helm, a graduate of the University of California Santa Cruz's prestigious science illustration program, painstakingly created original illustrations for What Tree Is That? based on her extensive training in biology and art. Her work has been displayed in juried exhibitions throughout the country and has appeared in numerous publications. Karina also teaches visual art techniques at art and natural history centers in and around Lincoln, Nebraska.
