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.
Introduction and population establishment of C. urophthalmum in Florida (United States) is well documented. Climate matches of 6 or higher are indicated for many parts of the Southeastern United States. Although the population has not spread beyond Florida since its initial discovery almost 30 years ago, spread of the population to areas with high climate matched is certainly possible and can be reasonably expected to continue without active eradication measures. The native fauna is potentially at a higher risk to disease and parasite transmission in the presence of C. urophthalmum because of the high rate of infestation found within this species. Further research is needed on this species.
