Site description (baseline)
A large, diverse, sparsely populated island closely connected to the city of Turku. Ruissalo is remarkable for both its natural and cultural history. The area supports about half of the natural Quercus forest in the country. Between and around the forests are numerous patches of farmland with narrow belts of reedbeds along the shoreline. The site also encompasses some small, barren islands lying off the main island.

Key biodiversity
An important breeding area for forest avifauna, especially for species of deciduous forests, such as Columba oenas. The site is also important for Strix aluco (10-50 pairs), Picus canus (10-50 pairs) and Dendrocopos minor (10-50 pairs), although populations of these three species do not meet the IBA criteria at this site.
