Keywords: Integrated Bedload Monitoring, Sediment Variability, Long-Term Monitoring Species diversity of aquatic life forms are significantly determined by the availability of different habitats and their composition. In this context, the bed substrate (bedload) plays an important role in regard to the ecological functionality. As aquatic habitat for macrozoobenthos or also as spawning habitat for gravel spawning salmonids such as the brown trout. In both cases, the availability of sediments deposited in various grain sizes is a prerequisite for the formation of adequate habitats. Since 2014 the bedload monitoring station located in the Gesäuse national park at the Johnsbach stream derives precious long-term nature-based data, fundamental to various riverine applications and basic research. This paper focuses on relevant issues for aquatic lifeforms, namely: sediment composition, dynamics and quantity.
