  • Introduction. The 21st meeting for specialists in air pollution effects on forest ecosystems “Forests under changing climate, enhanced UV and air pollution” was held on August 25-30, 2004, in Oulu, Finland, hosted by Department of Biology, Thule Institute and University of Oulu, on behalf of the IUFRO Research Group 7.04.00 “Air Pollution Impacts on Forest Ecosystems”. A satellite microscopy workshop was also held as part of the IUFRO Working Party 7.04.02 “Mechanisms of action and indicator development”. When studying environmental problems in forest ecosystems, particularly in trees, the key question is: which changes or injury do we observe and what is their origin? Field studies and experiments are carried out to document exposure and uptake of pollutants, effects at tree and ecosystem level, to prove dose-response relationship, and to clarify the multiple relationships existing between site factors, climate, pollutants, competition for resources, successional dynamics and tree/ecosystem responses. In the past 20 years, experimental conditions to test air pollution effects have constantly improved using increasingly sophisticated technical installations. These approaches have included greenhouses, climate chambers, open-top chambers, branch and single tree chambers, and recently various free-air release fumigations systems in tree plantations or forest canopies - all with the purpose of measuring the effects in near-natural systems. Research has also focused on the ‘mechanisms of action’ of different stress factors, such as gas exchange, anatomical and biochemical responses. Introductory work has been done using molecular biology methods. Applications using bioindication in the field (initially with exposed sensitive plants and recently with natural vegetation) have been developed. Results from O3 injury assessments were reported in different sessions of this meeting during which much new work was dedicated to understand the effects of increased O3, elevated CO2, nitrogen, and UV-B on ecosystems. Both field studies and experimental works were presented, providing evidence documenting the air pollution impact on forest trees and/or ecosystems in Europe and North America. Here we select and resume some key-results from the oral presentations, whose degree of innovation may contribute to address future research. (literal)
