Description :
The ecosystematical evaluation of different units of landscapes and the distributional pattern of floristical groups and different ecosystems is represented in Ecological Maps with vegetation units. Species diversity, the abundance of species and the occurence of autochtonous and allochtonous ecosystems indicate a precipitation gradient leading from SE to NW, which shows a different effectiveness regarding the conditions of topography, soils and geomorphology. The floristical research was supported by seed bank investigations, which confirm the highest species diversity in landscape units with distinct relief energy.
