Information on the Emerald Ash Borer
The EAB has killed millions of trees in southwestern Ontario since 2002. This highly destructive insect poses a significant economic and environmental threat to all forests and urban areas. The EBA attacks all species of ash (except the Mountain Ash-not a true ash). Here's some information on the signs to look for, and some resources for inoculations, if you wish to try and save your ash tree.
