According to the American Forests website, "As defined in the Checklist, trees are woody plants with one erect perennial stem or trunk at least 9 1/2 inches in circumference (3 inches in diameter) at 4 1/2 feet above the ground (breast height), a definitely formed crown of foliage, and a height of at least 13 feet. In contrast, shrubs are small woody plants, usually with several perennial stems branching at the base." Note that the "Checklist" referred to above is Agriculture Handbook 541.
