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 albertisii is a freshwater crayfish native to southwestern Papua New Guinea. It is in the aquarium trade in Turkey, Germany, and the Czech Republic, but does not appear to be in trade in the United States. C. albertisii has never been reported as introduced or established outside of its native range. History of invasiveness is uncertain. This species has a low climate match with the contiguous United States overall, and a medium match in Florida. However, the climate match was based on a general description of the species range because georeferenced occurrences are not available. Due to a lack of introduction history and distribution information relevant to assessing the invasive potential of this species in the contiguous United States, the certainty of this assessment is low. The overall risk assessment category is uncertain.
