What Makes a Tree 'Hazardous' in Spokane?
A hazardous tree isn't necessarily a sick tree — it's any tree whose failure could cause significant damage or injury. In Spokane's specific climate, the most common hazard categories are: drought-stressed ponderosa pine (compromised root systems and brittle wood), wind-damaged Douglas fir (visible cracks, hung limbs, partial trunk failure), beetle-killed conifers (structurally degrading every week), and aging silver maples and cottonwoods with hollow trunks. The 2015 windstorm and every major storm since has reinforced one lesson: trees fail under loads they handled fine for decades, because internal decay accumulates invisibly.
