Early Assessment of the Invasiveness of the Alien Plant <i>Vernonia amygdalina</i> Del. Introduced in China

may have substantial invasion potential, supported by high reproductive capacity, strong allelopathic effects, effective defense traits, and broad climatic tolerance. Moreover, current introduction and cultivation practices in southern China may further increase invasion risk by elevating propagule pressure. Preventive actions, including early detection, targeted monitoring, and surveillance systems will be important for managing this species and mitigating potential ecological threats. Our synthesis also highlights the value of assessing invasion risk before introducing non-native species.
