Potential Effects of Climatic Changes on Soil Water Status and Drought Stress Susceptability of Norway Spruce Stands in the German Alps

Description: Das Projekt "Potential Effects of Climatic Changes on Soil Water Status and Drought Stress Susceptability of Norway Spruce Stands in the German Alps" wird vom Umweltbundesamt gefördert und von Universität Bayreuth, Bayreuther Institut für Terrestrische Ökosystemforschung, Lehrstuhl für Bodenökologie durchgeführt. Predictions on future climate revealed increasing drought stress for Middle European vegetation because of decreasing precipitation and increasing temperatures esp in summer. The meteorologic conditions of southern Bavaria are somewhat unique in relation to other German Alps. The aims of this project are thus: 1) Modelling of forest growth of Norway spruce stands in the Alps under different climatic conditions based on the relation between yxlem water potential and growth. 2) Beside changes in temperature and precipitation, an increase of atmospheric CO2 is to be expected. This might cause an increased water use efficiency of the tress which might compensate the increased evaporational need. By coupling our soil water model to a physiologically based transpiration model we will be able to include different water use efficiencies in our szenarios. 3) The assessment of drought stress susceptability derived from single stands will be extrapolated to larger areas of the German Alps based on soil survey data. The identification of high risk areas will be usefull for future forest management.
