At least 20 Wisconsin counties now harbor emerald ash borer, the exotic insect that has decimated urban trees and forests in the eastern half of the nation.
To remind Wisconsinites that they have a role to play in the battle, the U.S. Department of Agriculture has declared May 18-24 Emerald Ash Borer Awareness Week.
This particular week was chosen nationwide because it includes Memorial Day weekend, the beginning of the summer tourism season, when the risk is high for people to move EAB and other pests to new areas inadvertently on firewood.
Since 2008, EAB infestations have been confirmed in La Crosse, Trempealeau and Vernon counties among many others. These counties remain under quarantine.
This summer, state and federal agencies will set more than 1,500 traps around Wisconsin to monitor for the presence of the EAB.
