In 1990, a large hurricane simulation experiment was initaited in a 0.8 ha manipulation (pulldown) and 0.6 ha control area of a maturing Quercus rubra/Acer rubrum forest in New England. 276 trees were toppled in the pulldown, using a winch and cable, in the Northwesterly direction of natural treefall from major hurricanes. Eighty percent of canopy trees and two-thirds of all trees greater than 5 cm dbh suffered direct and indirect damage. Twenty years of measurements were used to evaluate the trajectory and mechanisms of forest response after intense disturbance. Based on the patch size and disturbance magnitude, we expected pioneer tree and understory species to drive succession.Forest Ecosystem Monitoring CooperativeForest Research at Harvard ForestEmeryBooseprincipalInvestigatorSince 1907, the Harvard Forest has served as a center for research and education in forest biology and conservation. The Forest's Long Term Ecological Research (LTER) program, established in 1988 and funded by the National Science Foundation, provides a framework for much of this activity.Vegetation Response in Simulated Hurricane Experiment at Harvard Forest since 1990Wind disturbance profoundly shapes temperate forests but few studies have evaluated patterns and mechanisms of long-term forest dynamics following major windthrows.
