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.
Cuban bulrush (Oxycaryum cubense) is an aquatic macrophyte native to South America and is cryptogenic in Central America and Africa. The history of invasiveness for O. cubense is high. It has been documented as introduced in the southern United States and has impacted biodiversity and navigation and recreational use of waterways. The climate match is high. The areas of highest match are concentrated around already established populations in the southeastern United States. The certainty of assessment is medium. The overall risk assessment category is high.
