Ecological Risk Screening Summaries - High Risk

Please note that high-risk species are species for which particular caution is needed to reduce the risk of invasive problems to ecosystems of the United States. Great caution is needed when trading or acquiring high-risk species, particularly in parts of the United States where the environmental conditions in the wild have been identified as suitable for the survival of the high-risk species of interest. If the species you want is categorized as high risk, then please consider choosing an alternative species from the low-risk category. If new species are being considered for trade, then we do not recommend high-risk species.

Risk information is presented in the ERSSs. If you need assistance, please seek out professionals who are knowledgeable about the species and your particular situation. If further assessments are needed beyond the ERSS, we recommend relying on results from industry, State or Federal agencies, university researchers, and non-governmental organizations trained in invasive species risk assessment and risk analysis.

For more information on how ERSSs are prepared, go to Ecological Risk Screening Summaries.
