American walnut trees grow very widely across the eastern USA in mixed hardwood forests and on farms, concentrated in central states but spread from Texas to the eastern seaboard. The trees are one of the few hardwood species planted as well as occurring and regenerated naturally. They grow relatively tall and straight with few lower branches.


FIA data shows U.S. walnut growing stock is 137.8 million m3, 0.9% of total U.S. hardwood growing stock. American walnut is growing 4.8 million m3 per year while the harvest is 1.9 million m3 per year. The net volume (after harvest) is increasing 2.9 million m3 each year. U.S. walnut growth exceeds harvest in all major supplying states except Michigan.
