Abstract

We present a simple empirical model that allows an estimation of mortalitydue to spruce budworm (Choristoneura fumiferana) outbreak in relationto fire frequency and site characteristics. The occurrence of arecent spruce budworm outbreak around Lake Duparquet (48°30' N,79°20' W, ca. 300 m a.s.l.) in northwestern Quebec permitted a reconstructionof the stand composition before the outbreak, and also of the mortalityof Abies balsamea due to the outbreak. The basal area of A. balsameaincreases with time since fire in all site types but with increasingvalues for (1) rock and shallow till, via (2) till and mesic clayup to (3) hydric clay. Mortality (measured as percentage loss ofbasal area due to the outbreak) increases with time since fire butdid not vary with site type. The increasing abundance of A. balsameawith time since fire is mainly responsible for this increase inmortality. Mortality for a specific basal area is, however, lowerfor the more recently burned stands suggesting a significant residualeffect of time since fire. A landscape model integrating mortalitydue to the outbreak for stands of different age is developed. Bothabsolute and relative losses of basal area increased with the lengthof the fire cycles. According to this model, changes in fire cyclecould explain a large portion of the spatio-temporal variationsobserved in outbreak mortality in the southeastern boreal forestof Canada.
