Abstract in another language

Current climate change projections predict general warming and altered seasonal distribution of precipitation as well as increased occurance of extreme weather conditions in Central Europe. It is unclear if and how well native tree species can cope with these changes. The commercially most important tree species in Central Europe is Picea abies (Norway spruce). According to our current knowledge, P. abies is particularly affected by climate change. It is expected to be less relevant for forestry in many regions in the future. Non-native tree species may be increasingly necessary in future forestry. In this context, it is particularly interesting whether the North American Thuja plicata (western redcedar) is a suitable species for stable forests in future Central Europe. The annual radial growth of T. plicata and P. abies was analysed as well as the dependence of the ring-width on climate and weather parameters. It was hypothesized that the exotic western redcedar has higher radial growth rates and is less sensitive to drought stress than the native Norway spruce. Tree ring chronologies from six forest stands with T plicata and P. abies (overall 88 and 89 trees respectively, 35 to 57 years old) in southern Germany (Franconian Forest, northeastern and mid Black Forest, Tab. 1) were investigated. The influence of 30 weather parameters on the variation of the annual ring-width was tested statistically. The average ring-width of T plicata (5.39 mm) was conspicuously higher than that of P. abies (3.72 mm) (Tab. 2, Abb. 1). The pattern on the tree ring chronology curves in each population was similar in both species (Abb. 2). The ring-width of both species is significantly influenced by a number of climate and weather parameters (Tab. 4). With one exception (water vapor saturation deficit in May), the significant influence was qualitatively similar in each case for Thuja and Picea. Therefore both tree species react very similar to the variation of climate and weather and in particular to their extremes. T plicata is found to be not more sensitive to frost, but also not more tolerant to drought. Western redcedar is a highly productive forestry tree species in Central Europe under the current climatic conditions. However considering the present results, it is questionable if western red cedar will show good growth under changing future climate conditions and specifically if it is a better alternative for Norway spruce in times of global climate change.
