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 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.

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 in Europe and beyond participate in ICP Forests.

7th Meeting of the heads of the laboratories in Brasov / Romania

Together with 30 participants from 16 countries we had a successful meeting of the heads of the labs in Brasov/Romania from 5th till 6th of September 2019! The meeting was very well organized by Dora Lucaci and her team. We discussed the results of the last ring tests (water, foliage and soil). Limits for heavy metals (Cd, Co, Cr, Cu, Ni, Pb and Zn) in water samples were fixed and water ringtest will be performed annually. The future of aqua regia digestion from soil samples with microwave, mercury deposition samplers and determination of mercury in these samples were presented and discussed. Three presentations about phosphorous and phosphorous fractions in soil were given. The final version of the ICP-Forests Manual update was presented and the verification of the submitted data from the LQA file was started. The next meeting will take place in Birmensdorf/Switzerland in September 2021.…
