    ABSTRACT
    In this contribution, the presence of Dreissena polymorpha (Pallas, 1771) (Bivalvia Dreissenidae) in the upper course of the Tiber River, in the province of Terni in Umbria (Italy), is reported for the first time during a citizen science project. The only other record of the species in this river is downstream at 40 km from the sea. This alien species with high invasive potential causes serious damage to the entire ecosystem and its distribution must be continuously monitored and contained. Involving local communities through citizen science projects can increase the capacity of early detection plans and possible actions to reduce spread of the species.
