- •Distribution and impacts of freshwater invasive species are assessed in Europe.
- •Impacts are calculated at catchment scale and related to river ecological status.
- •High variation of impact magnitude and spp. occupancy within and across catchments
- •Eleven countries on twenty-five show high impacts at poor and bad river status.
- •The approach can guide more effective catchment strategies to tackle invasive spp.
