Hydrology, element budgets, acidification, nutrient N in a climate change perspective for the northern forest region

The aim of this paper is to discuss the potential impact of climate change on element budgets and acidity in northern forest ecosystems. A catchment approach should provide the most appropriate unit and to be investigated in several spatial scales. Future monitoring has also to address tree composition, forestry activities, follow the soil organic matter storage and include changes in hydrology with episodic extremes.
