Abstract
The pattern of distribution of endemic Fraser fir Abies fraseri in the S Appalachians is being affected by infestation of the exotic balsam woolly adelgid (BWA) Adelges piceae. Prediction of the effects of BWA requires an assessment of 1) the population dynamics of the BWA and the fir, 2) the prevailing physical conditions that affect the spread of BWA, and 3) the subsequent pattern of fir mortality. This paper predicts the patterns of fir mortality and recovery on an elevation gradient by using a population model with site-specific environmental conditions and ecological interactions. Temperature range and amplitude, which affect survival and development rates of BWA, can have an indirect influence on the spatial pattern of living trees. Persistence of both species, with oscillations in numbers over time and space, is probable. -from Authors
