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.
Euastacus urospinosus is an Australian crayfish native to high-elevation rainforest surrounding headwater streams. The known native distribution of E. urospinosus has expanded over the past ten years as more research has been done on this species. E. urospinosus has not been reported as introduced outside its native range, so any impacts of introduction remain unknown. Climate match to the contiguous U.S. is medium, with the highest matches occurring in Florida and Texas. Overall risk to the contiguous U.S. is uncertain.
