What Has Happened

Emerald Ash Borer Beetle The Emerald Ash Borer (EAB) is a destructive Asian beetle discovered in Ohio around 2003. Shortly thereafter, ash trees in Worthington began showing signs of infestation. At that point in time, there was no treatment available to fight the pest, and affected trees in the City Right-Of-Way were assessed and put on a timetable for removal. Many trees that were in severe decline have been removed, while others receive annual assessment. To learn more about the EAB and how to determine if your tree is affected, visit the EAB Info page.
