Populus grandidentata, commonly known as Bigtooth Aspen or American Aspen, is a hardwood tree species native to eastern and central North America. It is typically 50-75 feet tall with a trunk diameter of 1-2 feet. The wood is light brown with a reddish or grayish tint and has a straight grain and fine, uniform texture. It is easy to work with hand and machine tools, but can be prone to splintering. Bigtooth Aspen is commonly used for pulp and paper production, furniture, crates, and pallets. While it is not resistant to decay, the species is considered a species of least concern by the International Union for Conservation of Nature (IUCN).
