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 leckii is a crayfish species with a restricted native distribution in northern New South Wales, Australia. The climate matching analysis indicated a low match overall to the contiguous U.S., although medium matches occurred in some eastern states. This species was discovered relatively recently with a very limited range, so the history of invasiveness is likely nonexistent. However, without evidence to the contrary, the potential for injurious impact is still present. Florida and Washington prohibit the possession or trade of C. leckii. The overall risk assessment category is uncertain.
