Hanhisto meadow and land uplift (Säppi, Eurajoki)

The southern and eastern shores of Säppi are low-lying. They clearly show the gradual change in the nearby species structure (succession), which is due to land uplift (Post-glacial rebound). After the cobble beach, you come to a bank of bladderwrack (Fucus vesiculosus), piled up by the sea, which offers a fertile foundation for a rich variety of plants and microfauna. Depending on the moisture conditions, the next area is either a meadow or a herb-rich forest of black alders (Alnus glutinosa) flanked by a reed (Phragmites australis) bed. On the eastern shore, beyond the bank of bladderwrack, there is a fairly wide meadow, where typical species include lady’s bedstraw (Galium verum), lyme-grass (Leymus arenarius) and wavy hair-grass (Deschampsia flexuosa). There are also pools of freshwater created as a result of land uplift on the island. Waves raised by storms bring seawater into some of these. Their flora includes species such as Mackenzie’s sedge (Carex mackenziei), slender spike-rush (Eleocharis uniglumis), Hippuris x lanceolata, sweet grass (Hierochloe odorata ssp. baltica) and small bur-reed (Sparganium natans).
