Ecological Risk Screening Summary - Koonac (Cherax plebejus) - 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.

Cherax plebejus is a large, dark-colored crayfish native to Western Australia. Very little information has been published about this species. Climate match with the contiguous U.S. is unknown, as are potential impacts of introduction because no introductions of C. plebejus have been observed. The States of Florida and Washington prohibit possession or trade of this species. Overall risk posed by C. plebejus to the contiguous U.S. is uncertain.
