État de la populationTexte officiel évaluation IUCNExpert

This is a common and widespread species. Overall, the population for this species is increasing. There has been reported decline in Korea due to land reclamation.

Zostera japonica is an introduced species on the west coast of North America that came in with shipments of oysters used to support the local shellfish industry (Phillips and Shaw 1976). First reported from Willapa Bay, Washington, it spread throughout coastal Washington and now occurs from the southern coast of British Columbia, Canada to Coos Bay, Oregon (Harrison and Bigley 1982, Posey 1988) and Humboldt Bay, California (F. Short pers. obs.).

Description complète des menacesTexte détaillé évaluation IUCNExpert

In some parts of its range, mostly in Korea, Zostera japonica is threatened by aquaculture and hardening of shorelines (land reclamation). It is also affected by resuspended sediments that affect water quality.
