A model was developed to predict the weight of foliage at each age on a branch for a given whorl from undefoliated balsam fir (Abies, Balsamea (L.) Mill) the normal weight of foliage by age classes can be compared to the weight of foliage remaining on a branch to estimate recent, annual defoliation by spruce budworm.
