The Tira Islands ( Swedish Tira öar ) are 16 larger and some small islands in Lake Bolmen in western Sweden , which together cover an area of about 34 hectares. The archipelago was not mapped until 1932.
The islands consist mainly of rubble, gravel and sand that the glaciers of the Ice Age deposited in an 80 km long wall, in the middle of which the islands are located. Today the islands, which are up to 12 meters high and are partly thick and wooded with old trees, and the surrounding water form a 733 hectare nature reserve . Because of the occurrence of a rare cormorant subspecies ( Phalacrocorax carbo sinensis ), the archipelago has been classified as a Natura 2000 area since 1996 .
