Ecological Risk Screening Summary - Cherax gladstonensis (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.

Cherax gladstonensis is a crayfish native to coastal Queensland, Australia. Climate matching to the type locality of C. gladstonensis shows the highest climate matches within the contiguous U.S. occur in Florida and Texas. No introductions of this species have been reported, so impacts of introduction are unknown. Florida and Washington prohibit the possession or trade of C. gladstonensis. The overall risk assessment is uncertain because of the poorly-described range, lack of introduction history, low climate match score, and general lack of information available on the species.
