    firewood with eab damage
    Please help protect Oregon's forests by not moving firewood from other states or even long distances within the state. Other states have damaging pests and diseases that are not yet established in Oregon such as emerald ash borer, sirex woodwasp, gypsy moth, Asian longhorned beetle, and oak wilt disease.
    Even if you can't see any insects, holes, sawdust, or disease it doesn't mean that the wood doesn't have any invasive species hidden inside. There is a good chance that even the experts wouldn't be able to find organisms such as insect eggs the size of a pin head or microscopic fungus spores in a pile of firewood.

Oregon's latest outbreak appears to have peaked in 2011 at nearly 2.9 million acres infested. Population densities in the last two seasons suggest the outbreak is beginning to wane.


Pest Alert: Spotted wing drosophila (Drosophila suzukii)
spotted wing drosophila
Surveys conducted in Oregon found spotted wing drosophila (SWD) from Portland south into Douglas County. This fly is of concern because unlike most members of its family, which only attack overripe or decaying fruit, it attacks ripe, healthy fruit. Fruits attacked include apple, blueberry, cane berries, cherry, grape, peach, persimmon, plum, and strawberry. If you find SWD suspects or fruit that may be infested please contact the ODA at 503-986-4636 or 1-800-525-0137.
