Emerald Ash Borer – Information & Resources
Poughkeepsie Ash Tree Program
This project has been funded in part by a grant from the New York State Environmental Protection Fund through the Hudson River Estuary Program of the New York State Department of Environmental Conservation.
Emerald Ash Borer
The emerald ash borer, an invasive beetle from Asia, is firmly established among the ash trees of the City of Poughkeepsie. The map below was created by the Environmental Cooperative at the Vassar Barns using revised data from The City of Poughkeepsie Shade Tree Commission’s 2006 Street Tree Survey. Trees are classified as EAB-infested, Symptomatic of EAB, or Asymptomatic. More than half of all ash trees in the City display symptoms of EAB infestation, while about 9% show definitive signs of EAB colonization.

Our efforts to control the Emerald Ash Borer infestation gained some national media coverage on a recent episode of PRI Public Radio International. Click below to listen:
Emerald Ash Borer was discovered in the United States in 2002 after arriving in packing materials from Asia. This document outlines the history of EAB invasion as well as information on the beetle itself and its potential impacts on North American ash populations, as well as the challenges associated with its management.
What to Look For
The City of Poughkeepsie is home to almost 400 ash trees. Before we can look out for further signs of EAB infestation, we have to know how to identify ash trees themselves! Click this link for ash tree ID tips.
Emerald ash borers are tiny yet very distinct insects. If you want to know what to look out for, or you think you’ve spotted one and want to verify your ID, check out this resource from the New York Invasive Species Information website.
We usually see the evidence left behind by EAB rather than the beetle itself. There are several unmistakable signs of EAB infestation on ash trees. Learn to recognize them with this helpful document, and please report signs of insect damage when observed.
If an ash tree still appears healthy in the midst of an EAB infestation, there may still be time to protect it from insect damage using insecticides. Refer to this guide for information about the various types of available insecticide treatments.
Unfortunately, some insecticides may have undue effects on non-target organisms, such as pollinators or birds. This document answers some of the most common questions about the risks of insecticides used for EAB treatment.
