Welcome to ICP Forests

A programme aiming at a comprehensive compilation of information on the condition of forests in Europe and beyond

The International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) was launched in 1985 under the Convention on Long-range Transboundary Air Pollution (Air Convention, formerly CLRTAP) of the United Nations Economic Commission for Europe (UNECE).

ICP Forests monitors forest condition at two monitoring intensity levels:

The Level I monitoring is based on 5730 observation plots (as at 2024) on a systematic transnational grid of 16 x 16 km throughout Europe and beyond to gain insight into the geographic and temporal variations in forest condition.

The Level II intensive monitoring comprises 639 plots (as at 2023) in selected forest ecosystems with the aim to clarify cause-effect relationships.

At present 42 countries in Europe and beyond participate in ICP Forests. All data are available upon request.
