Emerald Ash Borer (EAB) (Agrilus planipennis)

The Emerald Ash Borer (EAB) is an invasive beetle that has infested Western New York ash trees.  This destructive pest spreads among the ash trees by feeding on leaves and under the bark, killing the tree.  The EAB infestations are expected to spread across all of New York State, eventually attacking all ash trees.

Erie County has developed a long-term strategy and has begun removing and replacing dead trees in public parks that have been affected by EAB.  This will be an ongoing process as the Emerald Ash Borer moves through Western New York. 

The Erie County Department of Environment & Planning and Parks, Recreation & Forestry are active members of the WNY Emerald Ash Borer Task Force in an effort to remain proactive with Emerald Ash Borer resources and strategies.

What Should Homeowners Do?

  • View the informational brochure, “Emerald Ash Borer: How You Can Help” for guidance on ash tree identification, EAB life stages, and signs of infestation. 
  • View the current EAB Risk Map  for Western New York to see where it has been identified.
  • If you live outside of WNY, please report your detection to Cornell Cooperative Extension - (716) 652-5400, Ext. #150.
  • Learn factors to decide whether to consider treating or removing infested trees from your property:
      • How healthy is your tree canopy? 
      • How large is your tree?
      • Is there much evidence of woodpecker damage on your tree(s)?
  • For more guidance on replacement, treating, removing, timbering or other EAB infestation please follow these links:
