Site description A very large area of outer archipelago covering the whole north-east part of the Gulf of Finland. The site comprises extensive areas of open sea scattered with several large and forested islands, and numerous small, rocky islets. There are some remarkable submerged ridges in the area, and, more importantly for the avifauna, extensive spawning areas of the Baltic herring.

Key Biodiversity The area holds the largest population of Larus fuscus fuscus in the country, and also is important for other archipelagic species such as Alca torda and Cepphus grylle. During spring migration hundreds of thousands of Arctic ducks stop over within the IBA.
