In response to the confirmation of emerald ash borer, an exotic beetle that infests ash trees, in more counties in Oregon, the Oregon Department of Agriculture has enacted a permanent quarantine (OAR 603-052-1075). The quarantine in Washington, Yamhill, Marion and Clackamas counties limits the movement of all plant parts of ash (Fraxinus spp.), white fringe (Chionanthus spp.) and olive (Olea spp.) outside of the counties.
The EAB quarantine in these four counties restricts the movement of tree debris, including logs, green lumber, nursery stock, scion wood, bud wood, chips, mulch, stumps, roots, branches and firewood of hardwood species.
The purpose of the quarantine is to prevent the spread of EAB by restricting the movement of potentially infested tree debris to unaffected locations. To learn more about the quarantine or where you can properly dispose of quarantined tree debris, consult the EAB webpage.
