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 parvus is a crayfish native to northeast Queensland, Australia. Very little is known about the species, in part because it was first described only 25 years ago and has a very restricted native range. Florida and Washington prohibit possession or trade of C. parvus. The climate matching analysis indicates low match with the contiguous United States, based on a very small and tropical source region. No introductions of this species have been reported. Overall risk assessment category of Cherax parvus is uncertain.
