Quality and uncertainty aspects of forest deposition estimation using througfall, stemflow and precipitation measurements
report
In order to gain a better understanding of the effects of air pollution and other stress factors on forests, a Pan-European Progfam for Intensive and Continuous Monitoring of Forest Ecosystems (the so-called Level II or Intensive Monitoring Program) has been implemented. In this context 858 permanent observation plots for intensive monitoring of forest ecosystems have now been selected (EC LIN/ECE, 1997),501 in the European Union and 357 in several non-EU countries. The Pan-European Program is based on both the European Scheme on the Protec tion of Forests 4gainst Atnospheric Pollution (Council Regulation EEC no 3528/56) and the International Co-operative Program on Assessment and Moni toring of Air Pollution effects on Forests (ICP Forests) under the Convention of Long-Range Transboundary Air Pollution (tlN/ECE). The aim of the Pan European Program is to contribute to a better understanding of the impact of air pollution and other factors which may influence forest ecosystems. In the Program a number of surveys are executed on all plots, such as crown condition assess ments, soil surveys, foliar surveys and increment studies. On a limited number of plots, deposition, soil solution and meteorological monitoring is performed. The monitoring started in 1994 and will extend over a period of at least 15-20 years. Details on sampling and analytical procedures are published in EU-Regulations and the manual of ICP Forests on methods and criteria for harmonised sampling, assessment, monitoring and analysis of the effects of air pollution on forests (IN ECE,1994).
