Latest results from the transnational forest monitoring under ICP Forests

The International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) determines the impact of air pollution and climate change on European forest ecosystems within the framework of the UNECE Air Convention.

To provide a regular overview of the programme's activities, the ICP Forests Programme Co-ordinating Centre (PCC) publishes an annual ICP Forests Technical Report summarizing key research findings. This year's report presents results from 32 of the 42 member countries and includes:

• a review of key findings in the scientific literature on the influence of nitrogen deposition, ozone, and heavy metals on forest ecosystems and on interactions between air pollution and climate change;
• a list of 70 scientific publications for which ICP Forests data and/or the ICP Forests infrastructure were used;
• an overview of data requests between January and December 2021 and ongoing projects;
• a review of the 9th ICP Forests Scientific Conference FORECOMON 2021;
• an overview of atmospheric deposition in European forests in 2020;
• an overview of tree crown condition across Europe in 2021;
• the history of the QA/QC working group in the laboratories and progress in ICP Forests data quality;
• national reports on ICP Forests activities from participating countries.

The report can be downloaded from the ICP Forests website.
