Chemical analyses are an essential part of forest ecosystem monitoring activities. Harmonized, well-defined, and documented analytical methods are an important part of a laboratory Quality Control program and are essential to maximize spatial and temporal comparability of monitoring data. Different quality and data consistency checks, plausible ranges for analytical results, use of reference materials, and control charts are described for internal laboratory Quality Control. On the other side, coordinated ring tests among participating laboratories are an integral part of external Quality Control. Organization of ring tests, evaluation, and the benchmark with tolerable limits are described and specified. Results for water, foliage, and soil ring tests and the evaluation of quality indicators within the European forest ecosystem monitoring program are reported.

Forest Monitoring

Chapter 18. Atmospheric Deposition to Forest Ecosystems

By: Karin Hansen,Anne Thimonier,Nicholas Clarke,Jeroen Staelens,Daniel Žlindra,Peter Waldner,Aldo Marchetto

Atmospheric deposition is an important source of macro- and micronutrients to the forest and also the most important channel for input of long-range air pollutants. This chapter describes the methods used for the determination of atmospheric deposition, especially in rain and snow, in forest ecosystems, including samplers for open-field bulk precipitation, throughfall, and stemflow. These measurements can be used to quantify deposition to forests, to evaluate trends in pollutant inputs, and as inputs to modeling of canopy exchange processes, acidification and eutrophication. A major difficulty in throughfall measurement is high spatial and temporal variations, so that great care must be taken to ensure that samples are representative for the forest stand. Care must also be taken to minimize chemical and biological transformations in the samples. Deposition measurements have contributed to policy development and will continue to do so.
