Atmospheric deposition to forests has been monitored in the frame of the ICP Forests programme with sampling and analyses of bulk and throughfall deposition at several hundred forested Level II plots for more than 15 years now. Current deposition of inorganic nitrogen and sulphate is highest in Northern Central Europe as well as in some regions in southern parts. In this study we compared linear regression and MannKendall trend analyses techniques. The choice of method had an influence on the number of trends identified as being significant. We showed that the minimal detectable trends can be estimated with the mean short term temporal variability of the deposition, which is to a large extent due to meteorological variations, such as the precipitation and circulation patterns. The overall decreasing trends for inorganic N and SO42- in the past decade of about 3% and 6% require time series of about 10 and 6 years respectively to detect a trend on a plot with statistical significance. Past reduction of human emission reduced atmospheric deposition of acidifying and eutrophying compounds. This could be confirmed due to the availability of long-term data series. However, further reductions are required to reduce deposition to forests below critical loads for the whole of Europe.

Aim of study: The main aim of the work was to summarize availability, quality and comparability of on-going European Research and Monitoring Networks (ERMN), based on the results of a COST FP0903 Action questionnaire carried out in September 2010 and May 2012. Area of study: The COST Action FP0903 involves 29 European countries and 4 non-COST institutions from USA, Morocco and Tunisia. In this study, the total of 22 replies to the questionnaire from 18 countries were included. Materials and methods: Based on the feedback from the Action FP0903 countries, the most popular European Networks were identified. Thereafter, the access to the network database, available quality assurance/quality control procedures and publication were described. Finally, the so-called “Supersites” concept, defined as a “highly instrumented research infrastructure, for both research and monitoring of soil-plant-atmosphere interactions” was discussed. Main results: The result of the survey indicate that the vast majority of the Action FP0903 countries participate in the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forest (ICP Forest). The multi-disciplinary International Cooperative Programme on Integrated Monitoring of Air Pollution Effects on Ecosystems (ICPIM) is the second most widespread forest programme. Research highlights: To fully understand biochemical cycles in forest ecosystems, long-term monitoring is needed. Hence, a network of “Supersites”, is proposed. The application of the above infrastructure can be an effective way to attain a better integration of research and monitoring networks at forest sites in Europe. Key words: supersites; European Research Monitoring Networks; harmonization; forest.

Tap av nitrogen med grøfte- og overflatevatn frå eng er særleg påverka av nedbørsmengde, tidspunkt for spreiing av gjødsel, jordart, kor sterkt det er gjødsla og driftsmåte elles. Kva gjødselslag som er nytta, hysdyrgjødsel eller handelsgjødsel, synest i mindre grad å verka inn.
