Hen Harrier SPA Habitat Map
This dataset provides a habitat map for the six Special Protection Areas (SPAs) classified in Ireland under Article 4 of the Birds Directive (2009/147/EC) for the conservation of the Hen Harrier (Circus cyaneus). The SPAs cover a combined land area of approximately 1,671 km². The classification followed a national survey of breeding Hen Harriers, which recorded between 128 and 172 breeding pairs. The map supports identification of suitable breeding and foraging habitat within these designated conservation areas and is relevant to national biodiversity and land-use planning work concerning this protected bird species.Under Article 4 of the Birds Directive (Directive 2009/ 147/EC) six Special Protection Areas (SPAs), covering a total land area of c.1,671km² has been classified for the conservation of the Hen Harrier Circus cyaneus in Ireland. A survey of breeding Hen Harrier reported that 128 to 172 breeding pai…
