Paper Summary

Eastern Canadian forests have long been subject to cyclical spruce budworm (SBW) outbreaks, with over 51 million ha of moderate to severe defoliation in 1975. Although SBW outbreaks subsided in most areas by the late 1980s or early 1990s, another outbreak is expected. This may be foreshadowed by SBW defoliation in Quebec, which has increased from less than 3000 ha in 2003 to over 2.2 million ha in 2012.

Given the likelihood of an imminent SBW outbreak in other areas, forest managers may soon be confronted with several important policy issues regarding mitigation measures. The aim of this paper is to present and interpret analytical results that may provide insight into those issues, and thus offer guidance for managing forests during an outbreak.
