Question: Driving through Pittsburgh, saw blackened, dead trees on highways. Pine needles brown, trunks black. What causes this? Will it reach Maine?
Almost certainly a forest fire. Fire scorches pines (browning needles) and chars hardwood trunks black. No known disease or insect causes such uniform blackening. Maine's different climate and species make spread unlikely.
