American red oak is the dominant species in the U.S. hardwood forests with distinctive grain, and wood that is not always red in colour. The name is supposedly due to the leaf colour in the fall. Red oak trees grow only naturally and almost exclusively in North America, although planted elsewhere. Forest Inventory Analysis (FIA) data shows U.S. red oak growing stock is 18.7% of total U.S. hardwood growing stock and that while 33.9 million m³ of American red oak is harvested each year, more than 32 million m³ is naturally growing over the same period. In general the sapwood of red oaks is light brown and the heartwood is often pinkish to reddish brown. American red oaks have very good overall strength properties relative to weight. Its main uses are furniture, flooring, doors and certain construction applications.
