The central archipelago in all its glory!

Gällnö is typical of the central archipelago. In geological, historical and biological respects, Gällnö represents a genuine archipelago environment, where the cultural landscape and buildings are unusually well preserved. Gällnö has a cultural landscape with relatively large, continuous arable fields, grazing areas and pastureland.

The Archipelago Foundation has owned several properties on Gällnö, centred around the Gustavsberg farm, since 1977. All the arable land is leased to active farmers on the island. The pine forests form the basis of  forestry operations, which are conducted with a strong focus on conservation. The shores consist mainly of rocks, both steep and flat, and there are also stony shores with reeds. Sandy beaches can be found on Brännholmen at Torsviken and Västerholmen’s eastern side.


Karklö’s landscape alternates between deciduous and pine forests, interspersed with small-scale farmland and grazing areas. The island is reminiscent of Gällnö both in terms of its geology and plant life. In addition to its open and well managed farmland, the central part of Karklö is characterised by shady, attractive hills of oak trees. On the northern part of the island, the hill reaches an impressive height of 33 metres above sea level. You can also find a soil type known as “marl” on the island’s northern side. Marl is calcium-rich soil that has been transferred to the mainland for use as a soil conditioner.


Idholmen is dominated by spruce forest and a relatively large number of aspen trees, which have grown in areas that had previously been cleared.


Björkholmen is now used only for grazing, with the animals grazing on the long, narrow meadows that run between hills and rocks.
