Changes in Forest Condition Associated with Gypsy Moth
Eight years after the beginning of repeated but not continuous attacks by the gypsy moth (Lymantria dispar), hardwood plots in the Pocono Mountain region of Pennsylvania had outgrown most losses. Basal area averaged close to preattack values, though with wide variation from plot to plot. Volumes per acre had gained an average of 8 percent. Before the outbreak, 87 percent of the plots were fully stocked or overstocked; after eight years 79 percent were in this condition but with a reduced oak component.
