Quercus wislizeni var. wislizeni

Interior live oak

Family: Fagaceae · Type: tree · Native

Interior live oak is a California native tree found in the Klamath Ranges, northern Coast Ranges, Cascade Range foothills, Sierra Nevada forests, southern Sierra Nevada, Tehachapi, Sutter Buttes, San Francisco Bay Area, southern Coast Ranges, Transverse Ranges, Peninsular Ranges, and eastern Sierra Nevada in interior canyons, slopes, and pine/oak woodlands at elevations below 1,600 meters. Flowering from early February to May, this tree produces small, inconspicuous flowers typical of oak species. Growing as a broad, spreading tree 10 to 25 meters tall with a sturdy, multi-trunked form, it develops a dense, rounded canopy. Its leathery leaves are 2 to 5 centimeters long, dark green and somewhat thick, with smooth to slightly toothed margins. The tree produces acorns that are important food sources for wildlife in California's interior woodland ecosystems.
