Ecological Risk Screening Summary - African Elodea (Lagarosiphon major) - High Risk

Species that are considered high risk have a well-documented history of invasiveness in at least one location globally, and a high or medium climate match to the contiguous United States.

Lagarosiphon major is an aquatic plant native to southern Africa and has been introduced in Europe, New Zealand, and parts of Australia. The history of invasiveness for L. major is high. Invasions of L. major have resulted in the loss of native plant species. Climate matching indicated the contiguous United States has a high climate match. The areas of high match are scattered across the contiguous United States from the southwest through the lower Great Lakes. The certainty of this assessment is high. The overall risk assessment category is high.
