The International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) was established 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 the influence of air pollutants, climate change and other stressors on the condition of forest ecosystems at two levels of monitoring intensity. The Level I monitoring is based on around 6,000 observation plots on a systematic 16 x 16 km transnational grid across Europe and beyond to provide insight into the geographical and temporal variation of forest condition. The Level IIintensive monitoring comprises over 600 plots in selected forest ecosystems with the aim of clarifying cause-effect relationships.
Currently, 40 European countries as well as the USA and Canada are members of the ICP Forests.
