Both nature and cultural history considered, Ruissalo is a valuable and versatile area. Ruissalo is characterized by the cultural heritage of old fields, gardens, villas from the 19th century, oak forests, and diverse nature.

The nature reserves of Ruissalo were extended notably in 2006 along with an agreement between the State of Finland and the City of Turku concerning land ownership. At the same time the requirements of both the Herb-Rich Forest Conservation Programme and the Natura 2000 network were met.
