Oregon White Oak
March 26, 1806, at Fort Clatsop, Oregon.
Tree with dense, rounded, spreading crown of stout branches; sometimes shrubby. Leaves 3-6 in (7.5-15 cm) long, 2-4 in (5-10 cm) wide. Height: 30-70 ft (9-21 m). Diameter: 1-2.5 ft (0.3-0.8 m).
In valleys and on mountain slopes; often in pure stands and with other oaks.
Southwestern British Columbia south to central California in Coast Ranges and Sierra Nevada.
The oak of greatest commercial importance in the West and the only native oak in Washington and British Columbia. The sweetish acorns, often common in alternate years, are relished by livestock and wildlife and were eaten by Indians.
