Dr. Brian Sturtevant, Research Ecologist, U.S. Forest Service Northern Research Station, will present results that suggest that a) past management created widely divergent landscape legacies, yet budworm host species patterns were only weakly related to these spatial legacies; b) spruce budworm disperse at a coarser scale than the fragmentation patterns created by land management; c) outbreak characteristics differed substantially across the differently managed landscapes. |

Landscape composition, rather than pattern itself, appeared to contribute to the divergent outbreak responses. This study is among the first to show that forest management can not only influence damage associated with defoliator outbreaks, but also the nature of the outbreaks themselves. |
