There are several counties in WI that are under quarantine due to EAB, This now includes Dane County. Here is the current Map of WI EAB Quarantines and known Locations.


On Friday, Nov 22, 2013, EAB was confirmed in an ash tree in the City of Madison in the Warner Park area on the City’s North side. The Forestry Section is currently assessing the infestation and will post more information on the website as it becomes available.

If you think your private tree is infested with EAB, please contact a private tree care company or certified arborist to verify the infestation at your own expense. City of Madison Forestry Section will be concentrating its efforts on city street trees.
