ABSTRACT: A hypothesis is presented that atmospheric deposition is predisposing Fraser fir to balsam woolly adelgid (BWA)‐caused mortality and that the amount of mortality in six Fraser fir zones is a reflection of the amount of atmospheric deposits in each zone. We argue that Fraser fir is a highly sensitive species to atmospheric pollutants, that BWA increases that sensitivity, and that the Fraser fir ecosystem is a primary depository of such pollutants. Alternative hypotheses are also discussed. It is likely that a number of factors, including patterns of atmospheric deposits, contribute to Fraser fir mortality patterns in the southern Appalachians.
