Emerald Ash Borer

The Emerald Ash Borer (EAB) has devastated ash trees in southwestern Ontario and parts of the United States since its discovery in Detroit, Michigan in 2002. EAB is an introduced insect pest from Asia that attacks and kills all species of ash (Fraxinus) trees. Note that the mountain ash tree is not a true ash tree (Sorbus sp.) and is not threatened by this pest. EAB is a major economic and environmental threat that has killed more than 20 million ash trees in Ontario. EAB was detected in Thunder Bay on June of 2016. In Thunder Bay, with over 25% of our city's municipal trees (and an unknown number of private trees) being ash, the invasion of this pest is of great concern. Learn how to properly ID ash trees (Fraxinus) and the Emerald Ash Borer beetle and don't move firewood. Let's prevent it's further spread!
