Defoliation coverages for five major forest insect pests in Canada have been prepared for the first time on a national, ecologically stratified, base map. Reporting in an ecological framework, while satisfying updated reporting needs for international and national requirements, gives greater detail about these insect disturbance events in the form of maps, tables, and histograms, and offers analytical opportunities for several ecosystem health issues, such as climate change. This Forest Health Network report focuses on spruce budworm (Choristoneura fumiferana Clem.), forest tent caterpillar (Malacosoma disstria Hbn.), jack pine budworm (Choristoneura pinus pinus Free.), hemlock looper (Lambdina fiscellaria fiscellaria Gn.), and mountain pine beetle (Dendroctonus ponderosae Hopkins) for the period 1980-1996.
