Description complète des menacesTexte détaillé évaluation IUCNExpert
Zostera caulescens is sensitive to pollution and reduced water quality is a particular threat. Habitat loss is also a major threat to this species, as is dredging.
Within its range in Japan there is industrial development in coastal regions, land reclamation, water pollution and disturbance of habitats by fish trawling. In South Korea there is a large amount of coastal eutrophication and some land reclamation.
