Growing in canyon bottoms and along creeks, this tree can be found from the mountains of the ponderosa pine zone through the foothills in the margins of riparian zones. It grows in the southwest quarter of New Mexico, in the southeast and central mountains of Arizona, and south into Mexico. Arizona walnut may reach up to 80' in height and three feet in diameter, but is generally much smaller and grows in scattered stands. It has little commercial value due to its scattered occurrence, but provides important cover, while the small nuts are important to squirrels.
