Oregon White Oak
Quercus garryana
The only oak native to much of the Pacific Northwest, this slow-growing species once shaped vast oak savannas maintained by regular Indigenous burning practices — landscapes now largely lost to fire suppression and development. Its acorns fed people and wildlife alike.
Where found
Open prairies, savannas, and dry foothills of the Willamette Valley and Puget lowlands.
Fun facts
- Gray squirrels, deer, and livestock all rely on its acorns and young shoots as food.
