Torrö Nature Reserve lies in the southernmost part of the Östergötland coast, an archipelago with wind-swept pines, bare smooth rocks, beautiful wild flowers and a rich bird life!

The reserve includes about forty islands, including Torrö. The larger islands are clad with rocky pine forests where the pines grow slowly and become gnarled with the effects of strong winds and salt while struggling to acquire water and nutrients for their survival. Those that survive are very old and provide shelter and food for insects and birds, which makes them very precious.

The smaller islands and cobs are often fertilised by bird droppings. This makes the orange lichens on the smooth rocks blaze with colour. Cracks in the rocks are filled with soil that allows a variety of plants to survive in this rugged environment. The Yellow Stonecrop and Orpine save their moisture in their fleshy leaves, while the Tufted Vetch, like all leguminous plants, can take its nitrogen from the air.

Of the larger birds in the archipelago the Herring Gull is the most common, but Oystercatcher, Common Sandpiper, Turnstone, Cormorant and Common, Arctic and Caspian Terns are often seen. The majestic silhouette of the Sea Eagle is a regular sight and at times the colourful Shelduck, flocks of Mute Swan and Goosander are seen on the sound between the islands and Åsvikelandet. The Ringed Plover nests on a couple of cobs. Two areas in the north are bird protection zones where visits are forbidden between 1 April and 10 July. A very good place for ornithologists to study migrating birds during the spring and autumn is at the tip of the Korsudden headland.

On the island of Lilla Rotskär the rocks have remarkable formations caused by erosion.

Torrö is a reserve with an active community with fishing being an occupation on the main island. Including water, it comprises 1100 hectares and is privately owned.
