Long-Term Ecological Research (LTER)/HFR006: Hurricane Simulation
Listed in NASA Earthdata CMR
HFR006: Trees will be pulled down to simulate hurricane damage in two mixed hardwood plots: (1) 0.35 ha, September 1989; (2) 0.6 ha, September 1990.
Description
In the first plot, the extent of damage, changes in microtopography, and vegetation regeneration will be measured. In the second plot, vegetation will be measured and mapped before the pulldown.
After the pulldown, selected areas will be treated with chronic nitrogen addition and/or deer exclosure. Measurements will include the extent of damage, changes in microtopography, micrometeorological conditions, vegetation regeneration, litter chemistry, and trace gas fluxes. The Harvard Forest LTER site (HFR) is primarily Eastern deciduous forest.
