The correlation method was used to examine the losses of volume after defoliation by the spruce budworm in the 1950's with relation to the tree's characteristics. The results show that the loss of volume and dbh are highly correlated and it will be possible to predict past losses by dbh with a linear model. This study is based on data from stem analysis of 40 dominant fir trees from north Gaspé Peninsula.
