The presented vegetational data includes recordes on different study sites around Obergurgl. Primary succession on alpine virgin soil was studied in the glacier foreland of the Rotmoosferner, under the aspect of plant sociology and population biology. Vegetational records were made with plots along an transect between Schoenwieskopf (2300 m) and Liebener Rippe (up to 3180 m). With increasing stabilization of the substrate and progression of soil development, a sequence of different stages of vegetation development can be observed. With increasing distance from the glacier, diversity and vegetation cover accumulate and pioneer stages close to the glacier evolve into grassland with closed structure.
