How badly can OPM damage trees?

Like all caterpillars, OPM feeds on the leaves of oak trees. High caterpillar numbers can result in severe defoliation, but so far no trees have been recorded as dying because of this. Normally defoliated trees produce leaves the following spring and recover. However, annual defoliation over a number of years can weaken trees which might over time result in oak tree decline.
