Determine the relationship between the timing of bud development at different levels in the canopy (upper, lower and regeneration).Establish a baseline for the timing and duration of bud development on hardwood trees. 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.
