Forest Pest Survey and Detection |
In partnership with the Wisconsin Department of Natural Resources, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has detected emerald ash borer (EAB) for the first time in Lincoln County. This ash tree-killing beetle was found at multiple locations in the city of Tomahawk and on county forest land in the town of Harrison on January 31. It appears to have been present in Lincoln County for some time prior to detection, with several symptomatic trees showing dieback, woodpecker flecking, epicormic sprouts, and D-shaped exit holes.
Lincoln County is the first new county detection of 2022 and marks the 62nd county detection since EAB was first confirmed in the state in 2008. There are no regulatory changes as a result of this detection. EAB was federally deregulated as of January 14, 2021, and Wisconsin instituted a statewide quarantine in 2018.
For more information about EAB and where it has been found, visit https://datcp.wi.gov/Pages/Programs_Services/EAB.aspx.
Note: DATCP will send notifications only when EAB is found for the first time in a county.
