In Oregon, the establishment of EAB could devastate whole habitat types that are dominated by Oregon ash, such as ash swales and sensitive riparian zones, as well as reduce urban forest cover. This pest has proven deadly to all ash species in North America and Europe, including the native Oregon ash (Fraxinus latifolia).

State officials are working to determine how far and how fast this destructive insect is spreading in Oregon.

OSU Extension gathered key resources below to educate on Emerald Ash Borer. Report EAB sightings online at the Oregon Invasive Species Council hotline.
