Ecological Risk Screening Summary - Cherax boesemani (a crayfish, no common name) - Uncertain Risk

Cherax boesemani is a New Guinean crayfish known only from a single drainage in West Papua. The aquarium industry has interest in this species, with the species commonly available in parts of Europe and available at least rarely in the United States. However, there is no record of introductions or invasiveness. C. boesemani has an overall low climate match for the contiguous United States. The overall risk assessment is uncertain because, although C. boesemani has limited range, a low climate match, and no history of invasiveness, popularity among aquarists does expand the opportunity for introductions, and invasiveness cannot be judged conclusively until there is a record of introduction.

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.
