Tree mortality and growth were examined in defoliated, insecticide treated, and undefoliated stands in the pandora moth outbreak area on the Kaibab National Forest. Tree mortality was less than 1%. Radial and basal area growth were significantly different among areas in trees ≥ 14 inches d.b.h. and increased significantly in the undefoliated area, while rates in the defoliated and treated areas remained unchanged. Defoliation loss was estimated at least 11 f.b.m. per acre per year.
