Ecological Risk Screening Summaries - Uncertain Risk

For species in trade and characterized as uncertain risk, we recommend that more in-depth assessments be relied upon beyond the ERSS to better define the species’ risk to U.S. environments, so that informed decisions on where, when, and how the species may be used that will minimize invasive risks can be made. If a species is not yet in trade and is uncertain risk, we do not recommend its utilization until further assessment occurs.

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.
