Abstract

The threatened species of the insect orders Heteroptera, Lepidoptera and Coleoptera found in Ruissalo, an island with widest oak forests of Finland, are listed. Of the 154 species of threatened Lepidoptera in Finland 12% (19 species) and of the 332 species of threatened Coleoptera 16% (53) are found in Ruissalo. A considerable part of the threatened species of both Lepidoptera and Coleoptera are dependent on oak. The most important areas of the oak forests are already under protection and the other parts of them belong to the national conservation program of herb-grass forests. A forestry plan prepared by the City of Turku considers the nature values of the island of Ruissalo.
