Dynamically simulating spruce budworm in eastern Canada and its interactions with wildfire

•Eastern spruce budworm representation was integrated into a dynamic global vegetation model (LPJ-LMfire).•Cyclical temporal patterns were determined by post-outbreak regeneration of host trees.•Spatial patterns were determined by density of host trees across landscape, driven by climatic and other environmental conditions.•Outbreak enhanced fire potential through temporarily increased fuel loads but long-term effect was small due to subsequent depleted fuel load.
