About

Notholithocarpus densiflorus, commonly known as the tanoak or tanbark-oak, is a broadleaf tree in the family Fagaceae, and the type species of the genus Notholithocarpus. It is a hardwood tree that is native to the far western United States, particularly Oregon and California. It ranges from 15–40 meters (49–131 feet) in height, with a trunk diameter of 60–190 centimeters (24–75 inches). There are a number of radical and incompatible perceptions of tanoak; it has been seen by some as a cash crop and by others as a treasured food plant, while yet others have considered it a "trash tree".

Where it grows

It is native to the far western United States, found in southwest Oregon and in California as far south as the Transverse Ranges and east in the Sierra Nevada. It grows from sea level to elevations of 1,200 m (3,900 ft).
