Situated in the Province of Turku and Pori in south-western Finland, this biosphere reserve comprises terrestrial and marine habitats, including coniferous forests, wood meadows, heaths, rocky meadows, rocky or sandy islets, arable land, seashores and open sea. It represents a coastal environment of small islands in the Baltic Sea. Island societies are small in scale, and people who have lived there for generations maintain close contact with the sea and nature. Traditional livelihoods such as fishing and agriculture are becoming less profitable, and the population has declined markedly since the beginning of the last century.
