Emerald Ash Borer Links & Information

The Emerald Ash Borer (EAB) was first spotted in North America in 2002 in both Michigan and Canada, and since then has moved southward and destroyed more than 20 million trees in both locations as well as in Maryland, Ohio, Indiana and Illinois.

The EAB was first confirmed in Chicago in June 2008, at 29th and State Street, and has since then expanded its presence to many other parts of the city. The City of Chicago continues to work with our government and external partners to implement an EAB Management plan designed to protect our urban forest. This is an evolving strategy that builds on previous joint efforts between federal, state and local governments in the impacted areas. It has included injecting more than 15,500 Ash Trees with an internal insecticide that protects the tree from the EAB for up to 3 years per treatment. We have also coordinated the release of thousand of incredibly small insects, or parasitoids, which kill off future generations of the EAB by laying eggs in their larvae and eggs.

The battle against the Emerald Ash Borer has also generated online information about this invasive species. Below are a few qvailable links that may be useful to you.
