Welcome to ICP Vegetation

The International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops

The ICP Vegetation was established in 1987 under the United Nation Economic Commission for Europe (UNECE) Convention on Long-Range Transboundary Air Pollution (LRTAP).The ICP Vegetation is an international research programme investigating the impacts of air pollutants on crops and (semi-)natural vegetation and reports to theWorking Group on Effects (WGE). The programme focuses on the following air pollution problems: impacts of ozone pollution on vegetation and the atmospheric deposition of heavy metals and nitrogen to vegetation. In addition, the ICP Vegetation is taking into consideration impacts of pollutant mixtures (e.g. ozone and nitrogen), consequences for biodiversity and the modifying influence of climate change on the impacts of air pollutants on vegetation. The results of studies conducted by the ICP Vegetation are used in assessments of the current, and predictions of the future, state of the environment. Thirty five Parties to the LRTAP Convention participate in the programme.

The programme is led by the UK, has its Programme Coordination Centre at the Centre for Ecology and Hydrology - Bangor and is funded by the Department for Environment Food and Rural Affairs(Defra).
