Évaluation des risques posés par la tordeuse des bourgeons de l’épinette (Choristoneura fumiferana) dans l’est du Canada

This report is intended to characterize risks posed by spruce budworm outbreaks to a wide array of forest values. The authors accomplished this by integrating the latest understanding of spruce budworm biology, ecology, and management; qualifying their confidence in that understanding; identifying gaps; and identifying research priorities that will reduce uncertainty. The latter four elements were part of a multifaceted risk analysis. This work is not a systematic review but rather a synthesis of knowledge by experts, with support from the literature and external review. Ultimately, this report is intended to be a reference for forest pest managers in developing contemporary strategies for spruce budworm management and to provide background for decision makers and policymakers whose goals are to minimize or mitigate risks associated with spruce budworm outbreaks. The report is also intended to help research managers and researchers identify areas of inquiry that will help address knowledge gaps and reduce existing uncertainty.
