Quercus lobata, commonly called the valley oak or roble, is the largest of the California oaks. It is endemic to the state, growing in interior valleys and foothills from Siskiyou to San Diego counties.[4] Deciduous, it requires year-round groundwater,[5][6] and may live up to 600 years. Its thick, ridged bark (resembling alligator hide) and deeply lobed leaves are characteristic, and assist in identification.
