Conservation status of two endangered freshwater mussel species in Bavaria, Germany: Habitat quality, threats, and implications for conservation management

1. The freshwater pearl mussel ( Margaritifera margaritifera ) and the thick-shelled river mussel ( Unio crassus ) are relatively widespread across Europe, but are strongly declining and are now protected by the European Habitats Directive. In the course of this study, 20 pearl mussel and 14 thick-shelled river mussel streams in Bavaria, Germany, were investigated. host physicochemical parameters were investigated, e.g. substratum quality, water chem-istry, redox potential, and turbidity. Furthermore, potential risks the were and assessed. 5566 0.85 at M. margaritifera sites, U. Other parameters such as redox potential or electric conductivity also more favourable habitat conditions in M. margaritifera streams. Unio crassus
