ABSTRACT. The emerald ash borer (EAB) is an invasive, wood-boring beetle that has the capacity to decimate entire populations of ash trees. Urban tree populations are especially at risk due to their high traffic, by which infested firewood and nursery trees can be transported. The City of Poughkeepsie, NY, has a substantial population of ash trees that are vulnerable to EAB infestation. Symptoms of EAB infestation were observed on ash trees in the outskirts of the City and sporadically throughout City streets. For this reason, the Environmental Cooperative at Vassar Barns has completed an assessment of EAB infestation in the City of Poughkeepsie. Working with data from a 2006 street tree inventory, tree points were plotted in ArcGIS using address geocoding. Tree locations were then ground-truthed and corrected in the field using the ArcGIS Collector app. Tree condition was assessed based on the presence of stress symptoms. Distinct signs of beetle activity, such as d-shaped exit holes and s-shaped galleries, were noted as indicators of EAB. Of 405 street ash trees, 34 (8.4%) demonstrated definitive signs of EAB infestation, while 283 (58.8%) appeared symptomatic for infestation. These results indicate that EAB is established among the City’s street ash trees and the beetle will likely spread to infest all or most of the City’s ash. The Environmental Cooperative plans to utilize this information in the creation of an EAB management plan, including a published version of the tree point map. This document will aid in the City’s future urban forestry maintenance.
