Estimated defoliation of northern red oak (Quercus rubra) and white oak (Q. alba) removed 40% of leaf area Weights of frass (insect feces) collected at the site were greater than at a nearby site of lower elevation that was not defoliated. Within a month of the outbreak, elevated levels of nitrate-nitrogen (NO
