Verbreitung, Status Und Habitatbindung Der Subspontanen Bestände Der Douglasie (Pseudotsuga Menziesii) in Österreich. Essl, F. Phyton - Annales Rei Botanicae, 45(1):117–144, 2005. abstract bibtex Douglas fir (Pseudotsuga menziesii, Pinaceae) is the commercially most important non-indigenous tree species in Central Europe. So far,an analysis of the invasion process in Austria and its effects has not been made. In this paper, subspontaneous spread, distribution, floristic status and habitat preference of Douglas fir in Austria are studied. At present, Douglas fir is confined to several localities in lowland regions in Austria. Growing sites are known from three federal provinces (Burgenland, Lower Austria, Upper Austria) in 19 mapping units (ca. 30 sqkm) of the floristic mapping project of Central Europe. The largest populations are located at the eastern rim of the Bohemian Mass. At the Manhartsberg-region, the core area of subspontaneous spread, young growth of Douglas Fir colonises 26.8 sqkm, of which 12.3 sqkm are densily colonised. Subspontanous spread of Douglas fir seems to have begun there at about 1975. It is there locally established in natural vegetation types (acidophilous oak forests) and according to Central European classification systems therefore an agriophyte. Experience from the invasion process in Germany, the habitat preferences of Douglas fir and the climatic and geological conditions of some regions make a regional conspicuous spread in Austria in the next decades probable. This applies especially for dry lowland territories at the eastern and southern rim of the Bohemian Mass and for lower parts of the eastern rim of the Central Alps (Rosalien-gebirge, Bucklige Welt, Günser Gebirge). Habitat preference of Douglas fir has been documented by 27 relevés. In Austria young growth preferably colonises open conifer-forests. Near-natural acidophilous oak forests (Sorbo torminalis-Quercetum) are affected by invasion of Douglas fir as well. Forest clearings and road embarkments of streets'in forests-are also colonised repeatedly. Douglas fir rarely invades other plant communities (e.g. Luzulo nemorosae-Fagetum sylvatici) in Austria.
