Mark record


The spread of exotic forest pests, whether insects or diseases, is a growing threat to Canadian forests and an international trade issue. Since the late 19th century, more than 40 exotic pests capable of causing considerable damage to our forests have been introduced into Canada, including the emerald ash borer, which has destroyed millions of ash trees to this day. The detection and identification of exotic pests are key elements in combating this threat and protecting forest resources.

Plain Language Summary

This publication reports on research work focusing on the identification and detection of exotic forest pests.

Natural Resources Canada and the Canadian Food Inspection Agency are working together to prevent the introduction of new pest species and limit their spread.

This collaborative effort has made it possible to draw up a profile of exotic fungi that are present on urban trees and to develop a molecular diagnosis kit for detecting pests that are invisible to the naked eye.

In the long term, this research work will increase our understanding of the biology of exotic pests and their pathways into Canada in order to guide the development of effective control methods.

Branching Out is a series of plain language fact sheets describing Laurentian Forestry Centre research projects.
