Hiiumaa islets

Year of compilation: 2000

Site description
A complex of shallow (<4 m) bays and small islets on the south-east coast of Hiiumaa island. There are reedbeds, coastal meadows and saltmarshes. The main exploitative land-uses are fishing, tourism and non-intensive agriculture.

Key biodiversity
The area is an important staging site for migrating wildfowl, and supports a diverse avifauna, with 190 species recorded (110 of which have been recorded breeding). Significant proportion (³1%) of national population breeding at site: Limosa limosa (min. 10 pairs).

Pressure/threats to key biodiversity
Major threats are posed by human disturbance of birds, tourism, unsustainable hunting, fishing, agricultural pollution, and overgrowth of coastal meadows with reed Phragmites as a result of undergrazing. The IBA is a planned core area of the West Estonian Archipelago Biosphere Reserve. Research involves monitoring of birds, seals (Phocidae) and plants.
