Changes in forest condition associated with gypsy moth have now been measured for two infestations: northeastern Pennsylvania (1971-79) and central Pennsylvania (1978-85). Despite the variation in changes inflicted across both affected areas, average damage levels were very similar in these case studies. Measurements taken before and after infestation indicate that changes in average plot volume were 8 and 9%, respectively. Before outbreaks in the respective areas, 87 and 86% of the plots were fully stocked or overstocked; afterward, 79 and 83% were in this condition but with a reduced oak component. North. J. Appl. For. 5:59-61, March 1988.
