Summary:

The information presented in this paper is directed towards plant scientists interested in determining the effects of air pollution stress on forest ecosystems. A mathematical model (FORET) designed to examine the successional dynamics of eastern deciduous forests has been used to study the long-term interactions of air pollution stress and forest community dynamics. Differential levels of growth reduction (0%, 10%, and 20%) were applied to trees in three sensitivity classes to simulate changes in biomass of both individual trees and of the forest stand. Results indicate that the response of individual trees in a forest stand may differ markedly from results predicted on the basis of responses determined in the absence of plant competition. Some species may show growth enhancement in spite of pollutant stress since they may gain a competitive advantage as a result of greater impacts on other species with which they interact in the successional process. Other species may experience much greater than anticipated impacts due to reduced competitive potential. We suggest that simulation models can provide a useful function in integrating the results of past research and by permitting projections thereof to extend our understanding of both the nature and extent of air pollution impacts on forest ecosystems.
