As the climate changes, it is thought that ice storms will begin to occur with increasing frequency. This project evaluates the damage and changes ice storms cause to northern hardwood forests in nutrient cycling. Ten 20x30 meter plots were established in a predominately sugar maple stand, with 4 icing treatments and 2 control plots. This data set includes soil nitrate (NO3-) and ammonium (NH4+) concentrations, microbial biomass carbon (C ) and nitrogen (N) content, microbial respiration, potential nitrification and N mineralization rates determined via lab incubation and in situ field incubations, denitrification potential, and organic matter content monitored in the Ice Storm Experiment plots at the Hubbard Brook Experimental Forest from 2015-2017.
