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 americana) and is not threatened by this pest.
In June 2016, the Emerald Ash Borer was officially confirmed in Thunder Bay. Read the City's news release announcing the discovery: Adobe PDF, 1 page, 128 KB
