The interconnecting waters of the FGSS open up several natural regions; as a result, the continuity from the sea to the spring runs as well as the connection of all subordinate rivers with each other is established. Water quality and biotope structures must meet minimum requirements so that there are no insurmountable obstacles to migratory or spreading animal and plant species.
