(2014): The Impact of Soil Conditons on the Growth of Douglas-fir in Austria
AUSTRIAN J FOR SCI. 2014; 131(2): 107-127.

Abstract:
The Douglas-fir, native to western North America, is a drought-tolerant species and considered as one of the most promising key tree species in Western and Central Europe for forest adaption under changing climate conditions. The wide native distribution range of the Douglas-fir, covering a large latitudinal and elevation range, constitutes genetically differentiated populations. Thus, the selection of suitable proveniences and site conditions are of major importance in guaranteeing a successful cultivation outside its natural distribution range. In this study, we investigate how environmental conditions may influence the growth of Douglas-fir in Austria and Southern Bavaria-fir stands. We develop a basal area increment model based on stand density, tree size and site conditions. Furthermore, the environmental factors climate, topography and soil and their relationship versus site index are investigated. Eleven Douglas-fir stands from Austria and Bavaria are randomly selected. The genetic seed sources are from the Western Cascades in Washington and Oregon. The 10 year basal area increment per hectare (BAI10) was modeled with a nonlinear power function explaining 77% of the existing variation.
