We investigated the long-term effects of drought and defoliation by forest tent caterpillars on trembling aspen radial growth in the province of Ontario using a dendroecological approach. Drought, as measured by Hogg's climate moisture index (CMI), was found to have no discernible impact on aspen radial increment in either northeastern or north- western Ontario during the study period 1930-2003. Forest tent caterpillar outbreaks were strongly decadal in periodicity in both regions and resulted… CONTINUE READING
