Emerald Ash Borer
Dorsal view of adult with elytra and wings spread.
The emerald ash borer (EAB) is an invasive beetle first introduced in the eastern U.S. that has wiped out native ash trees wherever it has spread. It was recently found in Forest Grove, near Portland. By all accounts, containment is not possible after it has become established. We can expect it to reach the southern Willamette Valley within ten years. The impact on our site will be significant.
