UPDATE 2/25/25: Emerald Ash Borer (EAB) 

At last night’s City Council meeting, staff provided an update on the local detection of the Emerald Ash Borer. To slow its spread, the City will begin removing infected ash trees.

 

**Infected trees were identified in Wyffles Park in August 2024.  They are scheduled to be removed at the end of March 2025.**

 

While the City did not receive forestry grant funding for mitigation efforts related to the Emerald Ash Borer, it remains committed to exploring alternative funding options to support residents in mitigating and responding to the impacts of EAB. Resources on EAB identification, mitigation, and upcoming events are available at www.OregonEAB.com, including a homeowner pocket guide now in four additional languages.

 

The City will continue sharing updates and resources as they become available via website, Facebook @city of woodburn, and WoodburnNOW app (available in iphone/android app stores)

Emerald Ash Borer (EAB) Information and Resources 

(Information from Oregon Department of Forestry)

Emerald ash borer (Agrilus planipennis) — commonly called EAB — is a destructive, invasive beetle that infests and kills ash trees (Fraxinus species). EAB has spread across North America since it was first detected in Michigan in 2002, killing hundreds of millions of ash trees. EAB was confirmed in Oregon in 2022, the first known case on the West Coast. Once EAB arrives in an area, it cannot be eradicated —which means it doesn't go away. Even though EAB will kill many ash trees in Oregon, there are steps we can take to slow its spread and limit its impacts.

 

Quarantine alert

Quarantine alert for the following counties:  Marion, Clackamas, Yamhill, and Washington.

What you can do:

•Do not move firewood or woody debris more than 10 miles from where you buy or collect it.

•Do not plant ash trees (Fraxinus species). Instead, plant a diversity of trees and plants that are appropriate for the conditions of the site.

•Learn to identify ash trees and the signs and symptoms of an EAB infestation.

•If you think you have found an EAB infestation, report it to the Oregon Invasive Species Hotline (online) or call 1-866-INVADER.

•Determine if you have ash on your property. If you do, discuss your options with an ISA-certified arborist before taking action.

•Sign up for Oregon Tree Health Threats, a monthly newsletter from Oregon Dept. of Forestry covering EAB and other forest health issues.

 

Taking action now will help minimize the impacts of EAB in Oregon.
