ICP Forests

The International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) aims at a comprehensive compilation of information on the condition of forests in Europe and beyond.

ICP Forests was launched in 1985 in response to wide public and political concern over extensive forest damage that had been observed in Europe in the beginning of the 1980s. It monitors forest condition in Europe and beyond 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 throughout the UNECE region participate in ICP Forests. Its Programme Co-ordinating Centre is based at the Thünen Institute of Forest Ecosystems in Eberswalde, Germany.
