Before the glacial period, beech trees flourished throughout much of the continent. Now, this species is confined to the eastern U.S. You may be wondering about the best ways to identify the American beech tree should you come across it in the forest. In addition to its signature beechnut fruit—brown, triangular-shaped nuts covered in spines—you can look at the characteristics of its leaves and bark. With this guide, you'll be able to point out the American beech on your next nature walk. Description and Identification Andrea Colarieti / Getty Images The American beech also goes by the names beech, beechnut tree, and red, ridge, or white beech. Its crown is rounded and sometimes oval in shape. The tree can reach between 60 and 80 feet tall, while its trunk can be two to three feet in diameter. You may identify an American beech by its bark. The light gray exterior remains smooth as the tree ages. Because of the thinness of the bark, beech trees too often suffer the carver's knife. If you spy initials carved in a tree, there's a good chance that it's an American beech. The dark green leaves of beech trees are alternate. They feature entire or sparsely toothed leaf margins with straight parallel veins on short stalks. Female flowers are small, single-sexed (monoecious), and borne in pairs. Male flowers are borne on globose heads hanging from a slender stalk, produced in spring shortly after the new leaves appear. The beechnut fruit is a small, sharply three-angled nut, borne singly or in pairs in soft-spined husks known as cupules. The nuts are edible but bitter with a high tannin content. Another identifying characteristic is the slender buds on American beech twigs, which are long and scaly. Native Range and Habitat North America's native beech is found in the East. Its range stretches from Cape Breton Island, Nova Scotia, to Maine, through southern Quebec, southern Ontario, and northern Michigan. Its northwestern limit is in eastern Wisconsin. The range then turns south through southern Illinois, southeastern Missouri, northwestern Arkansas, southeastern Oklahoma, and eastern Texas, and turns east to northern Florida and northeast to southeastern South Carolina. A variety also exists in the mountains of northeastern Mexico. American beech is most often found on moist slopes, in ravines, and atop moist hammocks. The tree loves loamy soils but will also thrive in clay. It will grow on elevations up to 3,300 feet and will often be in groves in a mature forest. Uses The American beech is typically used in landscaping. This shade tree has a vast crown that is appealing to many homeowners. The tree is also used for its wood, which makes great furniture, flooring, and railroad ties. According to the U.S. Forest Service Fire Effects Information System, beechwood has good burning qualities and is therefore favored as fuel wood. "The creosote made from beech wood is used to treat various human and animal disorders," the database says. Planting and Maintenance If you are interested in planting an American beech tree, keep in mind that these trees thrive in loamy-to-claylike soil and generally moist but sunny conditions. It grows best in USDA Plant Hardiness Zones 4 to 8. Make sure to water newly planted trees weekly in times of low precipitation. Even mature trees might need a little help staying moist in dry conditions as they are especially drought-sensitive. While fertilizer may be needed throughout the early years of an American beech's life, it should not be applied in the first year or after the fourth. This tree benefits from light pruning of branches that are diseased or damaged. This should be done in the winter or early spring, while the tree is dormant. Common Pests and Diseases Robert Winkler / Getty Images Scale and blight aphids are two common pests that cause problems because of the mold they secrete after feeding on American beech sap. The latter is sometimes referred to as the "boogie-woogie" aphid because "the nymphs lift their abdomens high in the air and thrash in unison" when a colony is disturbed, the N.C. State Extension says. High numbers of these aphids appear on the tree as fluffy, white masses. Scale aphids, rather, appear like small, shell-like bumps. Aphid infestations can lead to beech bark disease. The pests damage the bark and leave it vulnerable to fungal species that can damage vascular tissue. Look for small red dots developing on the bark—these are the fruiting bodies of the fungus. These clusters or "cankers" will continue to spread and eventually weaken the tree until it dies. Prevention of beech bark disease begins with controlling aphid infestations. Insecticides can be used, of course, but a more environmentally friendly solution to minor infestations is a quick blast of water. View Article Sources "Fagus grandifolia."
