Dear Colleagues,

The physiological responses of forest trees, as well as the response of forest ecosystems to environmental changes, are complex and multifaceted. Understanding the impact of environmental change on forests through the individual and combined effects of environmental drivers is crucial for predicting forest vitality and resilience.

We are looking for research dealing with various stress factors and disturbances impacting tree physiology and forest health, preferably as a part of complex interactions such as the following: combined heat and drought stress; hail, storms, and windbreaks; atmospheric deposition and climate change; and forest fires and erosion. Tree and forest ecosystem responses differ across environmental gradients. For instance, differing water availability and/or temperature conditions impact water…

It is with great pleasure that we announce the publication of the

ICP Forests 40th Anniversary Report - On the pulse of European forests. 40 years of pan-European forest monitoring: From air pollution to climate change

as presented during the 40th Anniversary Celebration in Dresden on 19 May 2025.

This glossy report presents a comprehensive overview of results from 40 years of transnational forest ecosystem monitoring in Europe and beyond under the UNECE Air Convention.

We hope you enjoy reading this report.

The registration for this year's

The ICP Forests Chairman and the Programme Co-ordinating Centre wish you

a peaceful and relaxing holiday season and a happy and healthy new year 2025.

Once again, we would like to express our sincere gratitude to all those involved in ICP Forests and especially the participating countries for their continued commitment and co-operation in monitoring forest ecosystems across the UNECE region.
