The spruce budworm [SBW] (Choristoneura fumiferana ((Clem)) infestation on Cape Breton island, Nova Scotia, reached a peak in 1976-1977 causing widespread mortality of balsam fir (Abies balsamera (L.) Mill.), white spruce (Picea Glauca (Moench) Voss), and black spruce (Picea mariana (Mill.) B.S.P.). SBW-induced changes to the merchantable component of the Island forests were based on analyses of data collected from 258 unharvested randomly established Permanent Sample Plots.
