🚨 HISTORIC FIND: Massive Emerald Ash Borer Infestation Confirmed in Salem, Oregon 🚨
Today Associated Arborists was on-site in Salem — Oregon's capital — for what is now a confirmed, large-scale Emerald Ash Borer (EAB) infestation. We worked alongside the Oregon Department of Forestry, the City of Salem, and the City of Keizer as this was verified in real time.
This is a serious moment for Oregon's urban forest. EAB has spread rapidly since it was first detected on the West Coast in Forest Grove back in 2022 — and what we saw today confirms this pest has a real foothold in the Willamette Valley's core.
Huge thanks to the teams who have been educating the arborists and community in the region! The teams from Salem, Keizer and ODF were on site quicker than the ghostbusters and these professionals are smart and motivated to protect our community. These foresters and municipal managers are amazing people that you can tell genuinely care for the community.

If you have ash trees on your property — in Salem, Keizer, or anywhere in the Willamette Valley — now is the time to get them inspected. Early detection and treatment can save a tree. Once EAB takes hold, the timeline moves fast.
