One of the challenges of interdisciplinary research is to consistently make available the data and products that have been developed in the individual disciplines and to guarantee their long-term availability. For this purpose, the website for the SASSCAL ObservationNet was developed. Biodiversity observatories have been established as research infrastructures that allow the monitoring of the impact of climate and other  environmental changes on biodiversity. Each observatory has a size of 1 km2 and is subdivided according to the needs of disciplinary research, but all of them follow a standardized sampling design (Jürgens et al., 2012). The observatories are studied by researchers from various disciplines including botany, zoology, agriculture, mycology, climatology, meteorology, soil sciences, remote sensing, anthropology, and socio-ecology. Information on changes in the biosphere will be made available in a similar way, as meteorologists are already able to describe climate change (Pereira et al., 2013). In the frame of the Global Observation System of Systems and its Global Biodiversity Observation Network (GEO BON), such plot-based observation sites are important research infrastructures.
