IUFRO Unit 4.01.08: Effects of environmental changes on forest growth

European Forest Institute (EFI)











The persistent drought and heat of the summer 2003 combined - in many regions - with minor precipitation in the preceding winter and spring have caused severe damages in forests in western, southern and central Europe. Besides visible, immediate or short-term impacts of drought and heat on forests, such as brown colouring and early fall of leaves as well as total disturbance of particularly young stands, there are further (still invisible) effects to be expected in long term. They are related to tree physiology, soil properties and nutrient availability in soils and trees, as well as to the root system reducing tree growth and vitality in the following years, having an impact on environmental, social and economic goods and services provided by forests. While numerous investigations have been undertaken on each of those topics, a synthesis about drought effects on forests taking different climatic scenarios into consideration is urgently needed. For this purpose, French and German scientists have initiated an expertise “Drought 2003” involving scientists of different disciplines, and resulting in this international scientific conference.


The aims of the conference are to

● discuss impacts of severe droughts on forests

● discuss research needs in respect to drought events and their impacts on forests

● present and discuss the results of the multidisciplinary French-German expertise

● explore links between researchers and disciplines concerning the topic

● encourage dialogue and cooperation in the future
