C. bartonii is a crayfish species native to eastern North America, with a broad distribution from Alabama and Georgia into eastern Canada. It is typically found in small streams with rocky substrates. To date, the species does not appear to be established in any location outside its native range, so potential impacts of its introduction remain unknown. Climate match to the continental
US is high; most areas of high climate match are within the native range of C. bartonii. The overall risk of this species is uncertain.
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.
