2022 Oregon ash tree threat: Invasive Emerald Ash Borer identified in Washington County.
The emerald ash borer, an invasive beetle first identified in Washington County, Oregon, in June 2022, threatens the state's ash trees. This pest, responsible for extensive tree loss in North America, can kill trees by disrupting water supply. Oregon officials recommend monitoring trees for signs of decline and exploring treatment options, including insecticides or removal. The loss of ash trees could adversely affect local ecosystems, particularly fish populations.
