Quercus gambelii is a deciduous small tree or large shrub often also called
scrub oak, oak brush or white oak.
It is an important food source for browsing animals. Acorns are frequently gathered by squirrels and stored for winter food.
Gambel oak was named after the American naturalist William Gambel (1821–1849).
