Emerald ash borer new locations in Wisconsin

Emerald ash borer (Agrilus planipennis) continues to be found in new areas. Regional Forest Health Updates were not sent during the 2016/2017 winter, so the list below includes new EAB finds from the last few months. Wisconsin continues to track EAB at the municipality or township level; infested areas are shown in green on the map below. If you know you have EAB please contact us with that information so we can verify the infestation and update the maps. If your area:

  • is not shaded in green on the map please contact DNR or
  • is not shaded at all on the map please contact DATCP.

You can reach both agencies from the menu options when you call 1-800-462-2803. EAB quarantines impact the movement of ash products and all hardwood firewood. For information on quarantine regulations check out the State and Federal Quarantines page on  Wisconsin’s Emerald Ash Borer Information Source.

EAB quarantine map. Counties shaded in tan are quarantined for EAB, and includes much of the southern half of Wisconsin, as well as other counties. Areas shaded in green are the townships and municipalities where EAB has actually been identified, and shows that not all counties that are quarantined are fully infested.

A graph of the Cumulative Community EAB Detections shows the number of townships and municipalities that have reported EAB in Wisconsin. 98 new municipalities and townships were added in 2016, pushing the total to more than 300 since 2007.
