Abstract

This book contains the proceedings of a workshop held within the framework of COST 612 in March 1988. Regional surveys of forest health rely upon visible symptoms of decline such as leaf loss, discoloration and crown structure. These may be caused, directly or indirectly, by air pollutants, but also depend on climatic, edaphic and biotic factors. There may also be significant interactions between different types of stress. The aim of the workshop was to evaluate the influence of air pollutants on visible symptoms, in the context of present understanding of the effects of other factors. The role of specific diagnostic tests was discussed and their application to field conditions on time scales relevant for quantification and diagnosis (i.e. cumulative or longterm responses).
