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.
The history of invasiveness for the stingray Potamotrygon schroederi is uncertain. No records of introductions were found. The climate match is low. The low match across the contiguous United States indicates that this species requires a fully tropical climate and there are no areas within the United States that would be able to support a population long term. The certainty of assessment is medium. The overall risk assessment category is uncertain.
