Birch and Beech TREES are two species of deciduous TREES that are commonly found in temperate climates. They are both members of the Betulaceae family, which includes a variety of other TREES such as alders, hazels, and hornbeams. Birch TREES are characterized by their thin, white bark and their small, triangular leaves. Beech TREES have smooth, gray bark and large, oval-shaped leaves. Both species are popular for their wood, which is used for furniture, flooring, and other woodworking projects.
