Divergent land management histories created differences in landscape patterns of spruce budworm host (i.e., spruce and fir) that were mapped using remote sensing.  Spruce budworm disturbance histories reconstructed via tree-ring analyses across this study area include a range of outbreak frequencies and intensities (lower left, where position roughly corresponds to geographic location).  The greatest variation in the time-series of outbreak patterns were explained by forest configuration, followed by forest proportion, and then the variance shared by these two variables, while climate accounted for comparatively little variation (lower left).
