  • In 1990-1991, five Scots pine forest stands of IV-VI age classes belonging to the Vaccinium, Myrtillus, and Cladonia forest-site type were observed along the atmospheric pollution deposition gradient in Estonia. In 1992, two new sites were added
  • five trees at each site. The impact of air pollution on the anatomical structure od Scots pine needles was studied in 1992. - (L'A.).

  • The results of IIASA (Austria) based on forest monitoring programmes indicate that nearly 80% of coniferous and 40% of deciduous forests in Europe suffer from air and soil pollution effects. Satellite observations show that in Central Europe
  • the currents of polluted air are spread by the wind to a distance of 700 to 800 km. An increase in precipitation acidity has been recorded in western Lithuania. For several months the pH indicator of precipitation was 3.8 to 4.0. In the eastern direction
  • , the pH indicator becomes more alkaline. This proves that pollutants moved to Lithuania from Western Europe, including neighbouring Poland. - (L'A.).

  • Climate and atmospheric deposition studies in forests. International Conference
  • Degradation of forest ecosystems became widespread throughout the Northern hemisphere in the 1970's. Research projects were developed to clarify the role of air pollution and changes in climatic conditions by using new monitoring methods. Based
