The spread of exotic forest pests represents a growing threat to Canada's forests and its international trade. Between 1981 and 1995, insects and diseases, both native and exotic, damaged approximately one billion cubic metres of timber in Canada. Detecting and identifying exotic pests is a crucial part of guarding against the dangers they pose and protecting forest resources.
