Methods

Saprobic system: At the selected sampling site, collect all organisms living in the water body that could be indicator species. Sampling should be as representative as possible of the watercourse reach. Since most indicator species would not be determinable with sufficient certainty in the field, the organisms should usually be killed and preserved so that the species can be determined later in the laboratory. Since not only the presence but also the abundance of the species must be known for the saprobic index, sampling must be done in such a way that this can be determined. The latest version of the DIN procedure lists about 200 microsaprobians and more than 600 macrosaprobians. In the procedure, the classification into abundance classes is sufficient for this purpose. Multi-habitat sampling: At each site, benthic macroinvertebrates were sampled within 50 m reaches according to the multi-habitat sampling protocol. A total of 20 sample units from representative microhabitats were taken according to the respective habitats coverage of the stream bottom. Sample units were taken by kick sampling an area of 25 x 25 cm (0.0625 m2) of the stream bottom in front of a shovel sampler (frame 25 x 25 cm, mesh size: 500 µm), to flush dislocated macroinvertebrates into the net. At each site, a total area of 1.25 m² was sampled. All samples were pooled in the field, preserved in ethanol (70% final concentration) and transferred to the lab, where samples were sorted according to the German macroinvertebrate monitoring standard protocol. Determination was to the species level where possible in line with the German operational taxa list (https://www.gewaesser-bewertung-berechnung.de/index.php/perlodes-online.html).
