EAB devastation

The Emerald Ash Boer (EAB), an invasive insect from Asia, is considered to be one of the worst alien forest pests to ever be introduced to North America. Since 2002, ash trees across large portions of the United States, Ontario and Quebec have been devastated by the EAB infestation.

EAB lay their eggs in ash trees. The larvae eat the soft wood under the tree’s bark, preventing the tree from moving water and nutrients between its roots and leaves, and killing it within one to three years.

Community engagement has been critical in raising awareness of the threat of EAB to Oakville's tree canopy. Keep up to date with all the news on EAB and other urban forestry related issues. Like us on Facebook and follow @OakCanopyClub on Twitter or email canopyclub@oakville.ca.

Oakville's EAB management program receives international recognition

Since 2008, Oakville has been a municipal leader in EAB management and we continue to take proactive measures to conserve our tree canopy. In 2015, forestry professionals from Canada, the United States and Europe were provided with a guided tour of Oakville’s urban forest. Part of a five-day International Advanced Practitioner Workshop organized by the University of Toronto, the tour provided an opportunity for forest health specialists from a variety of countries to learn about our best practices in EAB management. Sharing our expertise can contribute to early intervention and effective control of EAB in other regions.

Quarantine on ash and ash materials

The Canadian Food Inspection Agency (CFIA) has taken action to limit the spread of EAB by issuing a ministerial order to prohibit the movement of firewood of all tree species, and ash tree products such as nursery stock, logs, branches and wood chips, into or outside regions infested by EAB.

All of the greater Toronto area is inside an infested area, but regions to the north and east may not yet be infested. Take care not to transport firewood into these areas (eg. when visiting cottage country or camping north of the GTA). Review the current area regulated by the CFIA.
