Emerald Ash Borer: A Startling New Discovery

Ottawa, ON (July 25, 2008)- The Canadian Food Inspection Agency (CFIA), with the help of the City of Ottawa, confirmed the presence of Emerald Ash Borer (EAB) in the city. A month earlier, the species’ presence was confirmed near Montreal (in Carignon), another large metropolitan area. Since then, it has also been discovered in London, ON and Vaughan, ON.


EAB was introduced in North America from Asia. It was first noticed in 2002 in Detroit, MI and Windsor, ON. It had been present in these areas for several years before being discovered. The beetle burrows into ash trees and eats the inner bark, causing the infected trees to die within 1-2 years. Generally, infected trees don’t exhibit any symptoms until they start to die.
Since ash trees are commonly found in urban municipalities there is a concern that the presence of EAB will affect these tree populations.
Tree Canada is part of the Regional Forest Health Network, a group of organizations that works collectively to create awareness about invasive species. The Network is monitoring this situation carefully and is educating the public on how to act to inhibit the beetles’ spread.
If you are concerned about EAB in your area, take note:
* DO NOT move firewood. Buy it locally, burn it on site and DO NOT BRING IT HOME. EAB cannot fly far but it can be displaced by people moving firewood.
* There is NO NEED TO CUT DOWN healthy ash trees. EAB damages the wood only a few centimeters under the bark. For woodlot owners, your ash trees are still a valuable investment.
* For homeowners, EXAMINE your ash trees carefully for signs or symptoms of disease. Please consult Tree Canada’s Tree Killers website for more information on what to look for.
* If you do find EAB in your ash trees, DO NOT CUT DOWN the trees yourself. Contact the CFIA at 866-463-6017 to alert them of the possible infestation.
