Signature Oak
Posted on: February 6th, 2025 in Heritage Tree Details |


The Signature Oak is a symbol of the lasting importance of the Oregon white oak to the ecology and culture of the Willamette Valley. It is the oldest and largest tree in a grove of Oregon white oaks that predates settlement of the Willamette Valley by European immigrants and their descendants. The latest native inhabitants of the region were the Santiam group of the Kalapuyan tribe.
Native people in the region depended on oak groves as a source of acorns, camas and deer — important staples in their diet. Today more than 140 species of wildlife use oak groves as habitat for nesting, feeding, and resting.
