The most dangerous trees often look fine from the outside. Internal decay in Oregon species like Oregon white oak, big-leaf maple, and older Douglas fir can progress for years before the bark shows any sign of a problem.
There are clues a trained eye looks for even when the tree seems sound. Conks or shelf fungi at the base or trunk signal active decay. Hollow sounds when the trunk is tapped, soft or spongy wood near the root flare, old wounds that haven't callused, and cracks running parallel to the grain all suggest that what's inside may not match what's visible from the driveway.
For property owners across Lafayette, McMinnville, Newberg, Yamhill, and Yamhill County, summer is a practical time to walk the property and look at the base of large trees. If something prompts a question, it's worth a conversation with a certified arborist before fall storms make it more urgent.

Authentic job photo preferred: a close-up of shelf fungi, a trunk crack, or a soft-wood base on a Willamette Valley tree, or an arborist performing a close inspection of a large oak or fir. Images that show the arborist reading the tree communicate expertise most effectively. Real field photos outperform stock images.
