Ecological Risk Screening Summary - Corbicula loehensis (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 loehensis is a freshwater bivalve found in Sulawesi, Indonesia. According to Djajasasmita (1977), C. loehensis is found in Lake Towuti, Lake Mahalona, Lake Masapi and Lake Wawantoa. C. loehensis has an uncertain history of invasiveness; it has not been reported outside of its native range and is not in trade. The climate match for the contiguous United States was low with all individual states scoring a low match. No georeferenced locations were available for climate matching, so collection locations reported in the literature were used to select source points. The certainty of assessment is low because of lack of information. The overall risk assessment for Corbicula loehensis is uncertain.
