Site description (2000 baseline):
Site location and context
A complex of shallow (<2 m) bays and relict lakes on the southern coast of Saaremaa island, with small islets, vast reedbeds, coastal meadows and saltmarshes. The main economic activities are fishing, sheep-grazing and forestry.
A diverse selection of migratory waterbirds use the site for staging and/or breeding, with important numbers of several species. Significant proportion (³1%) of national population breeding at site:
Grus grus (10 pairs),
Larus canus (min. 400 pairs),
Larus marinus (20 pairs).
Pressure/threats to key biodiversity
The main threats are unsustainable hunting, intensive fishing, overgrowth of coastal meadows with reed
Phragmites due to undergrazing, and tourism. The IBA is a planned core area of the West Estonian Archipelago Biosphere Reserve, and is also a potential Ramsar Site. Research involves monitoring of migrating waterbirds.
