Invasive species of forest insects, diseases and plants have threatened Canada’s forested areas and urban environments for well over a century. Historically, pests such as chestnut blight and Dutch Elm Disease for example, have had severe impacts on the population of certain native Canadian tree species, in some cases almost eliminating them. The emerald ash borer, first observed in Canada in 2002, poses a serious threat to ash trees across North America. Strategies to eliminate or slow the spread of these destructive pests can be costly, so tools for assessing risk and best directing mitigation efforts can help ensure that resources are deployed most effectively at a time when decisions may need to be made quickly.
