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 31 of the 42 member countries and includes:

• an overview of atmospheric deposition in European forests in 2021;
• an overview on meteorological conditions in European forests in 2021;
• an overview of tree crown condition across Europe in 2022;
• the ICP Forests member states’ view on the current ICP Forests Strategy and future activities.

The report also includes:

• national reports on ICP Forests activities from participating countries;
• 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 65 scientific publications for which ICP Forests data and/or the ICP Forests infrastructure were used;
• an overview of the 29 data requests between January and December 2022 used in scientific studies.

The report can be downloaded from the ICP Forests website.
