Site description A very large archipelago with numerous islands lying offshore of Luvia and Rauma. The central archipelago of Rauma has many very large forested and inhabited islands with smaller islands and islets to its north and south. The other main area is the Luvia archipelago, comprising over 400 islands, most of which are rocky and stony and 0.4-4 ha in size. The larger islands of this archipelago are covered by Picea-dominated old forests, belts of Juniperus and Hippophae, and low heaths.
