With mature Douglas firs, Western hemlocks, and bigleaf maples frequently soaring over 100 feet above residential roofs in Thurston County, proactive hazard detection is essential for protecting your family, home, and vehicles.
Tree failure is rarely random; in nearly 90% of non-catastrophic windstorms, fallen trees displayed clear pre-existing structural defects that could have been identified during a professional Tree Risk Assessment Qualification (TRAQ) inspection.
Here are the top warning signs to inspect on your Olympia property:
1. Fresh Root Plate Lifting: If soil is heaving, cracking, or breaking root fibers on the side opposite a tree's lean, the root plate is failing actively. 2. Included Bark in Co-Dominant V-Crotches: When two trunks grow closely together in a tight 'V', bark pinches between them instead of fusing, creating an unbonded structural fault. 3. Bracket Fungus (Conks): Shelf-like conks sprouting from the trunk indicate extensive interior wood decay. 4. Canopy Dieback: Thinning crowns and dead terminal tips indicate root death or vascular disease. 5. Carpenter Ant Frass: Piles of coarse sawdust at the base reveal extensive hollowed-out internal cavities.
6. Deep Vertical Trunk Cracks: Seams running vertically down the trunk indicate severe shear stress or frost cracking. 7. Multiple Dead Limbs: Large dead branches ('widowmakers') over 4 inches in diameter can drop spontaneously in calm weather. 8. Wet Slime Flux / Bacterial Ooze: Fermenting sap bubbling from bark fissures signals bacterial wetwood. 9. Saturated Soil Puddling: Prolonged flooding softens the soil matrix, reducing friction hold on root systems. 10. Prior Root Severing: Excavations for utility trenches or driveway paving within the dripline often sever 40%+ of a tree's anchorage.
If you spot any of these red flags, do not wait for the next atmospheric river windstorm. Contact our certified arborists for an on-site structural evaluation and hazard mitigation plan.
