Past and present outbreaks of the balsam fir sawfly: An analytical review. Forest Ecol
Abstract Historical data of defoliation and population density were examined to determine whether a sustained outbreak of balsam fir sawfly (Neodiprion abietis Harris) in western Newfoundland, Canada is unprecedented in severity and duration. Results indicate that the current outbreak departs substa...
