Quercus ÃÂ alvordiana, the Alvord oak, is a hybrid oak in the genus Quercus. It is a naturally occurring hybrid between Quercus douglasii and Quercus john-tuckeri.
This hybrid is found throughout dry foothills of the Inner Coast Ranges (Diablo, Gabilan, Caliente, Temblor, Santa Lucia, Griswold Hills, etc.),Transverse Ranges (Tehachapi Mountains & Sierra Pelonas) and the southernmost portion of Sierra Nevada foothills. In certain xeric areas, hybrid swarms of Quercus x alvordiana become the dominant oak tree.
Quercus ÃÂ alvordiana is generally semi-evergreen, but is highly variable. The growth structure is fairly arborescent, usually multi-trunked, and can reach up to 6 meters (20 feet) in height.
