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.

Faxonius nana is a freshwater crayfish native to the Neosho River basin in Arkansas and eastern Oklahoma. It is reported to be available on the market for wholesale trade in Germany and the Czech Republic. In the Czech Republic it has a potential invasiveness (FI-ISK score) of 15 and a risk category (FI-ISK Category) of Medium. Data on impacts of introductions are lacking. Absence of this research makes the certainty of this assessment low. Climate match with the United States is high. Overall risk posed by this species is uncertain.
