Ecological Risk Screening Summary - Najas chinensis (a plant, no common name) - Uncertain Risk

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.

Najas chinensis is a freshwater plant species that is native to Eastern Asia (Japan, Korea, Taiwan, and parts of eastern China and Russia). There are reports of introductions in Greece, Italy, Turkey and western Russia. The History of Invasiveness is No Known Nonnative Population since there was no evidence that there were established nonnative populations. The overall climate match for the contiguous United States was High. The Midwest and Southeast coast were areas where the climate match was the highest. The certainty of this assessment is Low. The overall risk assessment category for Najas chinensis is Uncertain.
