Site details
Site description: An extensive shallow sea area with three large islands (Alvrø, Hjarnø and Endelave), supporting coastal saltmarshes, lagoons, cultivated land and scattered habitation. Several smaller uninhabited islets as well as intertidal areas are included within the IBA.
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: The site holds a large breeding colony of Phalacrocorax carbo and high numbers of wintering Aythya marila and Somateria mollissima. Breeding data are incomplete since numbers were not available for Alrø, Søby Rev and Svanegrunden islands. Several species listed on Annex I of the EC Birds Directive breed at the site, including Circus aeruginosus, Recurvirostra avosetta, Sterna sandvicensis, S. paradisaea and S. albifrons.
