Welcome to ICP Forests

– the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests operating under the UNECE Convention on Long-range Transboundary Air Pollution (CLRTAP) –

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

ICP Forests was launched in 1985 under the Convention on Long-range Transboundary Air Pollution (CLRTAP) of the United Nations Economic Commission for Europe (UNECE) in response to wide public and political concern over extensive forest damage that had been observed in Europe in the beginning of the 1980s. ICP Forests monitors forest condition in Europe at two monitoring intensity levels: The Level I monitoring is based on around 6000 observation plots 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 while the Level II intensive monitoring comprises around 500 plots in selected forest ecosystems with the aim to clarify cause-effect relationships. At present 42 countries participate in ICP Forests.
