Reforming Spartina alterniflora policies for sustainable coastal resilience: an evidence-based adaptive strategy.

The global debate on managing invasive Spartina alterniflora—eradication versus coexistence—remains unresolved. China’s nationwide eradication campaign risks ignoring regional ecological variations and potential benefits like sediment stabilization and carbon sequestration. We advocate adaptive, site-specific strategies that balance ecological risks with functional contributions, replacing one-size-fits-all eradication with evidence-based management.
