Emerald Ash Borer

The Emerald Ash Borer is a pervasive pest that threatens the health of our ash trees. Without adequate protection or action, large percentages of a city’s urban canopy can be lost, severely damaging the health of the overall urban forest. The good news is if you have ash trees on your private property, there are things you can do to protect them!

We at OUFC are pleased to share a helpful Emerald Ash Borer EAB resource for homeowners produced by the Ontario Ministry of Natural Resources, the Ontario Commercial Arborist Association and the City of Toronto.

This booklet has been designed for homeowners and other people who need to manage the emerald ash borer within an infested urban area. It will help you determine if you have ash trees on your property and if they have been infested by the emerald ash borer. We recommend that if you suspect your tree or neighbourhood is infested with emerald ash borer, that you consider management options including pesticide treatment or tree removal without delay. This booklet will provide you with information to guide your decisions.
