Sap flow of birch and Norway spruce during the European heat and drought in summer 2003 : 6th International Workshop on Measuring Xylem Sap Flow and its Application to Plant Science, 27-30 November 2006, Crawley, Australia
Climate change will have a large impact on all ecosystems of the earth. Especially forest ecosystems will bc affcctcd by the environmental changes. A very important issue in this context could be a possibly drastic restriction in the watcr supply of the trees and consequently a shift of forest communities There are some indications that the frequency of extreme heat and drought periods over large parts of Europe will increase (iPCC 2001). The consequences of these changes for the water supply of the European forests are not known in detail. In Central Europe, where Norway spruce is often planted on unsuitable sites, spruce stands outside of its natural range could run into problems. In this studv the differences in the effects of the drought 2003 on Norway spruce and birch. growing on heavy waterlogged soils were studied.
