For the dataset of all macrophytes recordings (biodiversity dataset ), a total of 75 submerged species is documented in Bavaria. The available taxonomic groups are mainly Spermatophytes (65 species), Charophytes (20 species), Bryophytes (5 species) and Pteridophytes (2 species). The complete abiotic and biotic data (environmental & biodiversity dataset ) cover 57 different species, whereas thebiodiversity time series dataset included 66 species. The total (depth-independent) gamma richness per lake ranges from 5 to 34 species of submerged macrophytes. The mean gamma richness averaged across lakes is 15.36 species with a standard deviation of 6.27 species.
