Emerald Ash Borer (EAB)

The Emerald Ash Borer is a forest pest that feeds solely on ash trees. This pest is causing severe damage throughout much of New York State, costing us the health of our forest ecosystems. Communities are left to foot the bill of removing hundreds of dying trees. This metallic green beetle is continuing to spread. 

 Visit's EAB webpage for information on forest pests including EAB, signs and symptoms of infestation, up to date population maps, and help with planning how to manage your ash.

 Learn how to identify the emerald ash borer and ash trees, as well as to monitor for new infestations and look for the EAB.

Check out our You Tube video to see work that was done to release biocontrol for EAB.
