Abstract:

Periodic outbreaks of black-headed budworms have been reported in southeast Alaska and on Prince William Sound since 1917. The 1950's outbreak caused severe defoliation of mature hemlock and almost one-third of net volume was lost in some stands. The defoliation trend-ratio of acres defoliated in a given year to acres defoliated the year before-was directly related to regional Temperature Index. Since virgin stands have recovered from past outbreaks, widespread defoliation need not be viewed with alarm.
