Abstract

    The purpose of this survey was to evaluate birch dieback and decline and to collect information on possible contributing factors. Paper birch stands defoliated by birch leaf miners and/or birch skeletonizers were monitored from 1993 to 2002. This survey mainly focused on paper birch stands but defoliated yellow birch stands were also evaluated. Sites were selected on state lands or stands with cooperative landowners, where no future logging was planned. Tree health assessments were conducted every-other year.
