Site description
An area of both outer and middle archipelago with a large number of islands, situated at the western edge of åland. Most of the islands are bare and almost treeless, but some larger ones hold small patches of forest, swamps, ponds and meadows. Signildskär, one of the largest islands, has the oldest bird observatory in Fennoscandia, founded in 1923. Migration observations have been carried out from the station, but the main activity now is ringing.

Key biodiversity
An important area for island-breeding species, most significantly Alca torda and Cepphus grylle, but also Somateria mollissima (2,000-5,000 pairs), Arenaria interpres (50-100 pairs) and Larus fuscus fuscus (50-100 pairs).
