Emerald Ash Borer (EAB) is an invasive insect native to Asia and has killed tens of millions of ash trees in urban, rural and forested settings (reprinted from Insecticide Options for Protecting Ash Trees from Emerald Ash Borer – North Central IPM Center).
Infestations of Emerald ash Borer have been identified in Greater Longfellow and in several other neighborhoods in Minneapolis. Ash trees provide a host to these invasive pests who feed on the trees until they are dead. With each dying tree the number of EAB grows and spreads to healthy trees in close proximity.
The Minneapolis Park and Recreation Board (MPRB) has provided the following documents and reports about EAB including how to identify it and treatment options. There are an estimated 250,000 Ash trees in the City of Minneapolis which is approximately 1/4 of the tree canopy.
