A drift line or wrack line,^[1] also known as a wash margin^[2] or wash fringe^[2] (German: Spülsaum)^[2] is an area of the shore on which material is deposited or washed up. It often runs along the margin of a waterbody and there can be several bands due to variations in water levels. As a result of the richness of nutrients that occur in such wash fringes, ruderal species frequently occur here, that, for example, on the Baltic Sea coast consist of grassleaf orache and sea kale.
