CCFM FPWG Spongy Moth Risk Assessment

This assessment was triggered by recent increases in detection of spongy moth (Lymantria dispar dispar), an invasive species, in un-infested areas of Canada, as well as outbreaks in areas where this pest is considered established. The objective of this assessment was to characterize the risk posed by spongy moth’s spread to currently un-infested forested areas across Canada, including the effect of climate change on the risk of spread and establishment of this insect. The assessment also identifies information needs that, once addressed, will help reduce existing uncertainties around spongy moth risk, and ultimately, will enhance prevention and management of spongy moth in Canada.
