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.Birch Condition SurveyData includes plot data, point data from 5 points per plot, and tree condition data collected every-other year.VMC.1140.2442mySQL/femc/data/archive/project/Birch_condition_survey/dataset/birch-condition-surveyxlsx1992-08-012002-08-01SPP_Tree SpeciesTree Speciesint601ITIS #19250, butternut (Juglans cinerea)318ITIS #28731, sugar maple (Acer saccharum)261ITIS #183397, Canada hemlock; hemlock spruce (Tsuga canadensis)375ITIS #19489, paper birch (Betula papyrifera)541ITIS #32931, white ash (Fraxinus americana)391ITIS #19504, American hornbeam (Carpinus caroliniana)97ITIS #18034, red spruce (Picea rubens)531ITIS #19462, American beech (Fagus grandifolia)371ITIS #19481, yellow birch (Betula alleghaniensis)935ITIS #25319, American mountain-ash (Sorbus americana)12ITIS #18032, balsam fir (Abies balsamea)746ITIS #195773, quaking aspen (Populus tremuloides)361None #, Custom Species Code ( )372ITIS #19487, sweet birch (Betula lenta)135None #, Custom Species Code ( )313ITIS #28749, boxelder (Acer negundo)325None #, Custom Species Code ( )2None #, Custom Species Code ( )319ITIS #28758, mountain maple (Acer spicatum)701ITIS #19511, eastern hophornbeam; hophornbeam (Ostrya virginiana)316ITIS #28728, red maple (Acer rubrum)129ITIS #183385, eastern white pine (Pinus strobus)260None #, Custom Species Code ( )761ITIS #24799, pin cherry (Prunus pensylvanica)675None #, Custom Species Code ( )833ITIS #19408, northern red oak (Quercus rubra)315ITIS #28754, striped maple (Acer pensylvanicum)633None #, Custom Species Code ( )855None #, Custom Species Code ( )345ITIS #26449, silktree (Albizia Albizia julibrissin)
