Emerald Ash Borer is here to stay. How we respond to this invasive species will determine the degree of its effect on our landscape. Our native ash trees and all 43 native arthropod specialist species dependent on these ash are threatened with functional extinction.
Emerald Ash Borer has cost the United States and Canada hundreds of millions of dollars since its introduction in the 1990s, and has the potential to incur a cost of $10.7 billion in the United States and $2 billion in Canada. Passive Management (doing nothing) is often the most expensive “response” and recent studies (CFS) conclude it is cheaper to treat city ash trees for a period of up to 20 years. A recent study has determined a correlation between tree decline caused by EAB and increased human illness.
The purpose of this website and the tagging campaign is to raise awareness about EAB so that Guelph residents may be equipped with the necessary information in order to proactively respond to this invasive species.
This initiative has been a collaborative effort by a number of Guelph residents including students from the University of Guelph and GUFF (Guelph Urban Forest Friends).
