Site details


Site description: A peninsula in the south-west of Islay, exposed to the prevailing south-westerly weather. This results in a highly oceanic climate with closer ecological affinities to western Ireland than to the rest of Britain. The IBA includes rocky shore, blanket mire, heathland and farmland habitats. The site is important wintering greese, and for breeding raptors and other upland species. Anser albifrons are the flavirostris subspecies.
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.
Delineation rationale: First identified in 1989 as The Oa, Islay; renamed in 2007. Digitised onto 1:50,000 scale OS maps.
