This study shows the macrozoobenthic biodiversity and the quality status of the Zostera marina meadow in the Gulf of Gdansk. To our knowledge, this is the first study focused on the assessment of environmental quality based on macrofauna occurring on such a small and specific habitat as a seagrass meadow.
The meadow is dominated by Zostera marina, but also Zanichellia palustris and Potamogeton pectinatus are present.
