The main purpose of this research Site is to study the characteristics of soils, waters and also snow of different study sites at different elevations in the alpine tundra of the Alps, with a particular focus on the effects of the environmental factors ( e.g. snow cover duration, soil temperature and moisture, air temperature) on the carbon and nitrogen dynamics. In summer 2016, other plots were added in order to investigate the relation between abiotic factors (both climatic and pedoclimatic), soil chemistry and vegetation in snowbed areas.
