Emerald ash borer (EAB) has been detected in three new counties. Affected counties include Washington, Yamhill, Marion and Clackamas. Tree materials of ash, olive, and white fringe tree must remain within the quarantine area. While this infestation is still distant from Coos and Curry Counties, it’s important to observe and report any symptoms that you see on Oregon Ash. These include crown dieback, D-shaped emergence holes, sucker shoots emerging from the trunk, S-shaped galleries under the bark, bark splitting on trunk or branches, woodpecker activity, tree dying from top down.
