Lineage |
This dataset displays distribution of Potamogeton friesii according to HELCOM RED LIST assessment based on the following data sources:
The records of species compiled from the Swedish Species Gateway (www.artportalen.se) and from the Finnish database of threatened species (Hertta). The species occurs also in inland waters, e.g. in Russia, southern and central Sweden and northern Finland (occurrences not shown on the map). It is possible that not all of the occurrences included in the map represent brackish water locations, e.g. the sites on the west coast of Sweden may also represent lakes/rivers that are just close to the coast.
