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.
Ludwigia linifolia is a species of wetland plant native to the southeast United States and southern Mexico. Introductions outside of its native range have been reported in the Congo and Myanmar but establishment is unknown. It is also reported as present in Brazil and Indonesia but there is some uncertainty in the native or introduced status. It is not present in trade. The history of invasiveness is classified as Data Deficient. Overall climate match with the contiguous United States is high. The largest area of high match was centered on and included the species’ native range in the southeast, however, it did expand in almost every direction outside the native range. The certainty of this assessment is low due to a lack of information regarding this species’ history of invasiveness and issues regarding nomenclature. The overall risk assessment category for Ludwigia linifolia is uncertain.
