Did you know EAB infested wood may not be moved into or within Madison city limits from April through September?  This is a City ordinance and subject to a fine up to $500 per day. Time outside of these six months (October through March) movement of infested wood is permitted. Simply, if you currently have infested wood leave it until October.

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, November 22, 2013, EAB was confirmed in an ash tree in the City of Madison in the Warner Park area on the City’s northside. As of April 2015, EAB has been found in 5 areas of the city of Madison:

1. Warner/ Berkley Park area
2. High Crossing Blvd/ East Towne area
3. Femrite Dr / Dutch Mill Rd area
4. Doncaster Park/ Mohawk Dr area
5. Middleton. N Gammon Rd/ Teideman's Pond area

Forestry Staff is systematically inspecting all ash terrace trees within the City of Madison. They are placing yellow dots on ash trees that do not meet the EAB treatment criteria.

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.

If you have an ash tree on your private property, you will need to make a decision to treat or remove the tree. If you do not make a decision, it will be made for you. All untreated ash trees will die, EAB is 100% fatal to untreated ash trees. To help you in your decision, we created a homeowner's decision guide.
