Site details
Site description: A large offshore archipelago in the middle part of the Gulf of Finland. The area holds many islands with rocky or stony shores. The largest of the islands are forested, with areas of meadows and Juniperus stands.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: An important breeding area for archipelagic avifauna, especially for Sterna caspia.
