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.

The history of invasiveness for Eichhronia crassipes is high. E. crassipes is native to the Amazon basin. The species has likely spread worldwide either incidentally or as an ornamental plant. Substantial peer reviewed literature is available documenting adverse impacts caused by this species. Climate matching indicated the contiguous United States has a high climate match with locations that have established E. crassipes populations. This indicates that there is suitable climate that could support further establishment of this species in the contiguous United States. The certainty of assessment is high. The overall risk assessment category is high.
