Emerald Ash Borer found in the City of Cornelius
The emerald ash borer (EAB) is a destructive insect that kills all types of North American ash trees (Fraxinus species). Unfortunately, EAB was found in Forest Grove in 2022 and in Cornelius earlier this year. Ash trees make up a large number of the trees in our community and are common in yards, parks, and streets. They help keep our communities healthy by providing shade, clear air, clean water, and wildlife habitat.
While EAB is here to stay, a coalition of local and state organizations are working together to slow its spread, and you can help! EAB and other destructive pests live in firewood. Infestations spread quickly when people transport firewood for camping or other uses. To help slow the spread of EAB, don’t move firewood more than 30 miles from where you buy or collect it.
You can further prepare for EAB by taking a few additional steps:
- Learn if any trees on your property are ash trees: https://extension.oregonstate.edu/gallery/recognizing-ash-trees-oregon-washington-northern-california
