Ecological Risk Screening Summary - Corbicula matannensis (a clam, 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. This additional information will help inform decisions on where, when, and how the species may be used to minimize risks of them becoming invasive

Corbicula matannensis is a freshwater bivalve found in Sulawesi, Indonesia. C. matanennsis is found in Lake Matano, Lake Posso, Lake Mahalona, Lake Towuti, Tonusu River, and Lake Posso area. C. matannensis has an uncertain history of invasiveness because it has not been reported outside of its native range or found in trade. The climate match for the contiguous United States was low with all States having a low individual Climate 6 score. No georeferenced locations were available for climate matching, so collection locations reported in the literature were used. The certainty of assessment is low due to lack of information. The overall risk assessment for Corbicula matannensis is uncertain.
