Description: Does forest land subject to intensive outbreaks of gypsy moth (Lymantria dispar L.) become less susceptible to defoliation? A model for estimating the likelihood of gypsy moth defoliation has been developed and validated. It was applied to forest-inventory plot data to quantify trends in the susceptibility of forest land in south-central Pennsylvania during a period of intensive infestation. Results show that even though susceptibility of the region's forest apparently has deciined, the potential for future infestations remains relatively high.

Keywords: Forest health, defoliation, susceptibility, hazard classification, Lymantria dispar L.
