We summarise the current knowledge about the Polish population of the Chinese pond mussel. At least 53 locations of the Chinese pond mussel have been confirmed in Poland taking into consideration a literature survey and our own research data comprising new unreported sites. S. woodiana is mostly present in fish ponds (69.8%) but for the last few years it has been discovered in lowland rivers, canals and wetlands, too. Considering these population figures the current data about the distribution of S. woodiana seem to be underestimated. The spreading rate described in the literature and already available knowledge about S. woodiana's biology and its resistance to the environmental conditions indicate that the species should be consider as a really risky invasive species. We suggest that monitoring of S. woodiana presence and abundance should be conducted.
