About
Quercus gambelii, with the common name Gambel oak, is a deciduous small tree or large shrub that is widespread in the foothills and lower mountains of western North America. It is also regionally called scrub oak, oak brush, and white oak.
The common and scientific names, Gambel oak and Quercus gambelii, were named after the American naturalist William Gambel (1821–1849).
Where it grows
The natural range of Quercus gambelii is centered in the western United States and northwestern Mexico in the states of Arizona, Chihuahua, Colorado, New Mexico, Sonora, and Utah. It also extends into Nevada, Wyoming, Idaho, Nebraska, the Oklahoma Panhandle, Coahuila, and into the Trans-Pecos region of western Texas.
Uses
Historically, acorns from Gambel oak provided a reliable source of food for Native Americans. If bitter, tannins can be leached from the acorns.
