Vegetation of pine (Pinus sylvetris L.) forests subjected to intense air pollution stress in the impact zone of one of the largest air pollution sources in Lithuania – the mineral fertilizer plant Achema data were analysed to determine eutrophication effects between 1988 and 2004. The study sites were established at 3-22 km distances in the prevailing wind direction (70–90 azimuth to the east from the plant) where vegetation data from pine stands which had first been surveyed by prof. S.Karazija in 1987-1988 were available (further referred as 1988). Stands with an age of 55 years with vegetation assigned to the Vaccinio-myrtillosa site type and with similar dendrometrical characteristics were preferred and were investigated in July, 2004.[...].
