Annual measurements of tree phenology to establish the timing of developmental events and trends, especially as they relate to changes in weather or insect and disease occurrence.Tree Phenology Monitoring: Bud developmentHalmanJoshuaJohnsonMichaelSimmonsTomWilmotSandraLawsonSeanDillnerDanclimate changeplant phenologyforest disturbancecanopiestreesBud Phenology 1992 - 20031992-04-072003-05-23Measurement of hardwood species spring phenological stages at Proctor Maple Research Center, Underhill, VTDetermine the relationship between the timing of bud development at different levels in the canopy and establish a baseline for the timing and duration of bud development on hardwood trees.Z0013_BudPhen92_03VMC.13.14mySQLHalman J., and S.
