Emerald Ash Borer Evening Workshops

Emerald Ash Borer Evening Workshops

October 5 & 6, 2022 (4PM-6PM)

Emerald Ash Borer Has Been Found in the Pacific Northwest . . .

. . . and it’s bad news for ash trees.  Emerald ash borer is an invasive beetle that became established in the U.S. in the early 2000’s near Detroit, MI.  It has since killed hundreds of millions of ash trees in the eastern U.S. in Canada and is considered one of the most destructive invasive pests in history. Until recently, it has not been moved west of the Rocky Mountains but this year it was found outside of Portland, Oregon.

This will have big impacts on forest owners in southwest Washington, where the native Oregon ash occurs more frequently.  However, other ash species like green or white ash are also commonly found in landscapes, which means urban and suburban areas will also be affected throughout the state.

It is only a matter of time until the beetle is found in Washington, so now is the time to prepare.  This workshop will focus on properly identifying both the beetle itself and the early symptoms on trees.  We’ll also discuss ways to improve early detection, management implications, and species options for replacing ash-dominant areas.

Both workshops will cover the same material.
