Presentation
Besides visible, immediate or short-term impacts of drought and heat on forests, there are further effects to be expected in the medium and logn-terme. While numerous investigations have been undertaken on various topics to assess the impacts of drought on forests, a synthesis is needed. For this purpose, French and German scientists have initiated the "drought 2003" expertise , involving scientists of different disciplines and countries; The scientific conference of Freiburg aimed to present and discuss the first results of this expertise. A total of 46 presentations and 16 posters were proposed to the 115 participants from 14 coountries (Germany, France, Switzerland, Italy, Slovaquia, Finland, Romania, Denmark, USA, Sweden, Australia, Russia, Austria and Spain).
