Intertidal and probably shallow subtidal Zostera marina beds provide food for a variety of wildfowl. Brent and Canadian geese rely on Zostera marina for a large proportion of their food. Declines in Brent geese and wigeon parallel the decline of Zostera marina. Little evidence to support the hypothesis that Zostera marina beds are nursery areas for fish
The presence of seagrass beds reduces water flow and increases sedimentation in their locality and may be important in coastal defense. Their loss may increase wave energy reaching the shore and accelerate erosion. Zostera marina is also protected under the Berne convention.
