Arctic coastal saltmarshes

Description (English)

Salt marshes along muddy and sandy intertidal shores in Arctic Europe dominated by halophytic plants with a circumpolar distribution. Stands are usually small and often occurring in a mosaic with bare sediment, as they are subject to erosion by waves and ice. Although the tidal differences are relatively low, the species composition varies according to the frequency and duration of flooding.
