Ecological Risk Screening Summary - Cherax wasselli (a crayfish, 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.

Cherax wasselli is a crayfish native to Cape York, Queensland, Australia. Very little is known about this species. The species has an overall low climate match to the contiguous U.S. and no documented history of introduction outside its native range. The Florida Fish and Wildlife Conservation Commission and the Washington Department of Fish and Wildlife have both listed C. wasselli and other species of Cherax as prohibited species. Further information is needed to adequately assess the risk this species poses, so the certainty of this assessment is low. The overall risk assessment category is Uncertain.
