Ecological Risk Screening Summary - Dreissena carinata (a mussel, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

Dreissena carinata is a mussel indigenous to selected freshwater lakes within the Balkan region of Europe. However, despite taxonomists’ efforts to address the ambiguous Dreissena genus, the taxon and distribution for D. carinata is still somewhat debated. There are no reports of D. carinata beyond its native range, so the history of invasiveness is uncertain. Climate match to the contiguous United States was low overall, with high matches found locally in Massachusetts, Rhode Island, and six western States. The overall risk posed by D. carinata is uncertain.
