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.
The history of invasiveness of Cipangopaludina japonica is not documented. There are no well documented impacts of C. japonica, however, it is widespread in the United States. The climate match is high. This is not unexpected as this species is already present in many of the areas with the highest climate matches. The certainty of assessment is medium. The overall risk assessment category is uncertain. There is a likelihood that this species could spread further within the United States.
