Spruce Budworm ( Choristoneura fumiferana (Clem.)) defoliation of balsam fir (Abies balsamea (L.) Mill,) and spruce (Picea sp.) stands in eastern Canada causes substantial reduction of timber volume yield, which must be taken into account in forest management planning. This required data to quantify the relationships between defoliation, forest stand increment and timber yield. In this paper, we describe the establishment and measurement methodology of a network of permanent sample plots in New Brunswick, designed to provide information on effects of budworm defoliation on yield for a variety of stand types.
