A Budworm Vigor-Resistance Classification for Spruce and Balsam Fir
Abstract:A spruce budworm epidemic again threatens the spruce-fir pulpwood forests of the Northeast. One defense against this insect is through silviculture. The author suggests selective-cutting methods to make spruce-fir stands more resistant, and offers a tree-classification system as a guide for selecting trees to cut or retain.
