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.
Echinodorus paniculatus, Amazon Sword, is a plant that is native to much of Central and South America. It is sometimes present in the ornamental trade. E. paniculatus can be purchased online in the United States. However, sometimes plants sold under this scientific name are another species, and E. paniculatus is sometimes sold under a different scientific name, making it difficult to track trade volumes. There are reports of introductions in gray literature, but no peer reviewed studies documenting established non-native populations, or impacts of introductions. The History of Invasiveness is classified as No Known Nonnative Population. The overall climate match for the contiguous United States is medium. There are areas of high and medium match from Virginia to Texas, in the Southwest, and along the Pacific Coast. Everywhere else was low match. The certainty of assessment is low due to lack of data. The overall Risk Assessment Category is Uncertain.
