Site details
Site description: A group of islands in the Bay of Bothnia. The oldest islands are heavily forested, the youngest (more recently formed by continued land uplift) are sandy or swampy with scattered stones. Human impact is minor.</P>
Rationale for qualifying as KBA: The most important group of islands for birds in the Bay of Bothnia. The numbers of <I>Larus fuscus fuscus</I>, <I>L. marinus</I>, <I>Sterna caspia</I> (50 pairs, 120 birds in spring and 250 birds in autumn) and <I>Alca torda</I> are probably the most significant. The area is also one of the most important staging areas for moulting <I>Anser anser</I> (1,200 birds) in the country. Species of global conservation concern that do not meet IBA criteria: <I>Polysticta stelleri</I> (non-breeding), <I>Haliaeetus albicilla</I> (max. 3 birds, passage).</P>
Manageability of the site: Site identified based on BirdLife International's Important Bird and Biodiversity Areas, under which manageability is strongly recommended but not explicitly documented
