ABSTRACT
Air pollution is considered a key stress factor affecting the annual ring widths of the trees, especially living in industrialized areas. The Silesia-Krakow Upland is one of the most polluted areas in Poland. Scots pine stands living there have been under influence of air pollution for a long period of time. Dendrochronological analysis in five separated transects, which were performed in this region, showed the abrupt and usually long term reductions observed in radial increments of sampled pines. The abrupt increase of reductions started in the beginning of 1960s. Most of them occurred in the years 1960–1990, after this period the number of Scots pine trees with reduced annual increments decreased considerably. The distribution of reductions in particular sites, especially of the Olkusz transects, indicate a distinct relationship between the amount of reductions and distance from local source of pollution. On the other hand the similarity in temporal distribution of reductions in all transects indicate that the studied area was probably also under influence of air pollution of a regional type.
