Ecological Risk Screening Summary - Banded Killifish (Fundulus diaphanus) - 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.

The history of invasiveness for Fundulus diaphanus is not documented. There were records of introductions but no information on any impacts from those introductions. There are areas of very high match outside of the native range of the species, indicating there are favorable climate conditions for further establishment of populations outside the native range. The certainty of assessment is medium. The overall risk assessment is uncertain.
