Abstract: The Monitoring net of forest ecosystems in the least polluted areas of Lithuania was established during 1989-1992. The main aim of the study was to determine and predict the condition of Pine stands and their changes with respect to the regional variation of pollutant load and meteorology. Data on pine crown condition collected in Auk taitija National Park for 19 years allowed analysing key factors responsible for changes in forest conditions on a regional scale in Lithuania. Our earlier investigation revealed that defoliation of Scots pine (Pinus sylvestris L.) is closely related to air concentrations and wet deposition of acidifying compounds. In the present study we would like to check the hypothesis that meteorological parameters could reduce negative effect of acidifying compounds and improve pine condition under the rapid climate change condition. The obtained results revealed that spring and summer precipitation and mean winter temperature were shown to be the key factors affecting defoliation. High wind speed also deteriorated pine crown condition. Recent warmer winter and autumn seasons, increasing humidity of vegetation and decreasing wind speed over the dormant period should increase tolerance of pine trees to phytotocic affects of air pollutants including surface ozone and acid deposition in north-eastern part of Lithuania in the near future
