Emerald Ash Borer

Apr 15th, 2015 | By | Category: Spring 2015

The Emerald Ash Borer is an Asian beetle that made its way to Toronto from Detroit, Michigan, first detected in our city in 2007.  It happily infested trees for more than three years before it was discovered by city arborists.  The beetle bores into the trees and prevents the flow of nutrients to the top canopy, eventually destroying the whole tree.  It has bored its way into 1 in 12 trees across the city. There are approximately 860,000 ash trees in the city and we are in danger of losing them all as early as 2017.  Half a dozen ash trees in East Lynn Park near Danforth and Woodbine Avenues are being treated by arborists by injected the trees with TreeAzin, a biological insecticide.  This process will be repeated every two years.  But because so many of the ash trees are on private property, it is important that we check to find out if our trees are infected.  The following two sites will help in this process:

There is an excellent video on this site by Greening Ward 32, a community group dedicated to green living, sustainability, parks, gardens and clean food:
