Large birch trees are easy to maintain and are used in the manufacture of many items, including furniture, skateboards, guitar amplifier, railroad ties, medicine and fuel.

Birch trees are noted for their peeling bark that begins as a brown color and turns white as it ages.

The paper birch is native to North America. The smooth white bark and ornamental green leaves of the paper birch make it a favorite for its beauty. The European white birch is often seen in urban areas. This tree has a smaller stature than the paper birch but is notably colorful in the fall. The gray birch has a tall trunk and is the only birch that does not have peeling bark. The yellow birch has a vast root system and takes an extended time to grow to full height. The bark of this tree curls and has a golden-yellow to yellow-orange color.
