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.

A programme tailored for comprehensive information on forest condition in Europe

ICP Forests was launched in 1985 under the Convention on Long-range Transboundary Air Pollution of the United Nations Economic Commission for Europe (UNECE) due to the growing public awareness of possible adverse effects of air pollution on forests. ICP Forests monitors the forest condition in Europe, in cooperation with the European Union using two different monitoring intensity levels. The first grid (called Level I) is based on around 6000 observation plots on a systematic transnational grid of 16 x 16 km throughout Europe. The intensive monitoring level comprises around 500 Level II plots in selected forest ecosystems in Europe. Currently 41 countries participate in the ICP Forests.

A research on radioactivity in Mount Ida (Kazdagi)/ Turkey

In 2010–2012, an extensive study was performed in forest sites of Mount IDA (Kazdagi)/Edremit 26 years after the Chernobyl accident. The 137Cs activity concentrations were determined by gamma-ray spectrometry in the forest soil layers (OL, OF + OH and A horizons) separately. Based on 341 surface soil samples and 118 soil profiles, activity concentrations of 137Cs in OL horizons varied between 0.25 ± 0.14 and 70 ± 1 Bq kg−1, while the ranges of 137Cs activity concentrations in OF + OH and A horizons were 13 ± 1–555 ± 3 Bq kg−1 and 2 ± 1–253 ± 2 Bq kg−1, respectively. Cesium-137 deposition in the study area was estimated to be in the range of 1–39 kBq m−2 and a linear relationship between the deposition of 137Cs and the altitude was observed. The distributions of 137Cs activities in OL, OF + OH and A horizons throughout the region were mapped in detail. The highest 137Cs activities were found in OF + OH horizons, with markedly lower 137Cs activity in mineral horizons of soil profiles.… Continue

New Mobile App for Ozone Injury Assessment

Dear Colleagues,

We would like to draw your attention to a new Mobile App for Ozone Injury Assessment, developed by ICP Vegetation. We encourage in particular the ozone experts among the ICP Forests community to apply and test the new application.

We welcome the app as a great and timely idea which may help drawing more attention to the ozone issue world wide. However, being aware of the issue of quality assurance and quality control, ICP Vegetation is keen on receiving records from ozone experts during the test phase to further develop and improve the app - in collaboration with ICP Forests and taking advantage of the existing expertise and advanced protocols. Hence, a closer collaboration between the two ICPs is anticipated and very…

Soil Solution

What kind of lysimeter are you using for intake of soil solution samples. You know , we need to use can be done of the DOC analysis which should be lysimeter. I would appreciate if you could give the name of the company.

Best regards,
