Tree with smooth bark is a term used to describe two types of trees, BIRCH and BEECH. BIRCH trees are deciduous trees that are native to the Northern Hemisphere and have a white bark that peels off in thin layers. BEECH trees are also deciduous trees that are native to temperate regions of Europe, Asia, and North America and have a smooth, gray bark. Both trees are popular for their aesthetic appeal and are often used in landscaping.
