The research team found that dune area loss across the four shorelines ranged from 18% to 45% after the storms, according to the study. Only 10% to 50% of dune volume had been recovered by September 2024, when Maine’s dune building season ended for that year. AdvertisementThe UNE research team is still collecting data on how the dunes have recovered after two full growing cycles, Kochtitzky said.
