Description complète des menacesExpert
Zostera asiatica is sensitive to pollution, and reduced water quality is a threat.

Within its range in Japan there is industrial development in coastal regions, water pollution and disturbance of habitats by fish trawling. In South Korea, there is a large amount of coastal eutrophication.

The recruitment rate of this species is estimated at five years, and therefore it is relatively slower to recolonize.

Mesures de conservation recommandéesExpert
The distribution of Zostera asiatica falls into protected areas in South Korea (Environmental Conservation Areas or Special Coastal Management Areas). Zostera asiatica is protected by 'The Marine Ecosystem Conservation and Management Act' in Korea.  There are some site-based conservation measures in place.

It is unclear if the federal, provincial or state, or local administrative laws and ordinances recognize this species in the Northeast Pacific.

Zostera asiatica is ranked as Vulnerable (vulnerable stage) in the Red Data Book of threatened Japanese plant species (2000).

More research is needed regarding the population size and distribution of this species, and population trends should be monitored.
