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.
The history of invasiveness for Elimia livescens is not documented. There are records of introduction into the Hudson and Mohawk rivers via the Erie Canal from its native range in the Great Lakes Basin. There were no records of actual impacts from that introduction, but there could be hybridization between Elimia livescens and E. virginica which is native to that area. The climate match is high. The highest matches were in or just outside the species native range. If the native range was removed from the results, the overall climate 6 score would decrease. The certainty of assessment is medium. The overall risk assessment category is uncertain. The history of invasiveness is inconclusive and the native range of the species confounds the results of the climate match.
