The City of Madison EAB Task Force and Forestry Section of the Parks Division, in following the outline of the EAB Plan Update of September 2013, will continue to provide updates with currently accepted Integrated Pest Management Plans (IPM). The EAB Task Force will highlight actions taken to mitigate the EAB threat, latest technical/ biological advances and other key issues that impact Madison's urban tree canopy. The USDA's Emerald Ash Borer Biocontrol Program initiated a biological control effort through the use of stingless parasite wasps that attack EAB larvae. The wasps are not expected to eradicate EAB, but are seen as a way that may help control EAB as part of IPM. Wisconsin is one of ten states involved in the research. The release of these wasps in Wisconsin will have no impact on the planned treatment or removals of ash trees in Madison neighborhoods. City Forestry will continue to treat and remove trees as planned.
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.
