Treating Parkway Ash Trees
The Emerald Ash Borer (EAB) is an invasive pest that attacks and kills ash trees, which are native to Illinois and commonplace in Naperville. To combat EAB, the City developed an EAB management plan to protect its urban forest. To learn more, visit the Emerald Ash Borer story page on the City's Open Data Naperville portal.
