Because these driving forces develop independently from each other and not homogeneously within the area, measurement results from a limited number of sites cannot easily be transferred to other sites. Thus, a simple statistical approach or the simu

Since German reunification in 1990, the quantity and chemical composition of emissions have changed drastically (Bellmann ., this volume). By 1992, emission of SO. had been reduced to 40%, alkaline dusts to 20% and NO. to 80% of the values

Firstly, the diameter increase is only proportional to the stem wood production if the tree mortality and the heightdiameter-relation of the trees
