The EU Birds Directive requires member states, among other things, to designate special protection areas, SPAs, for birds requiring special attention, including vulnerable and rare species and migratory species. It also obliges member states to designate wetlands of international importance.
The main selection criteria in relation to SPAs have included the following: that the area is used regularly by 1% or more of the population of bird species listed in Annex 1 of the birds directive; that the area is used by 1% or more of the population of a regularly occurring migratory species; and that the area is used by over 20,000 waterfowl or 20,000 seabirds in one season.
Other criteria include issues relating to population size and density, species range, breeding success, history of occupancy, multi-species areas, naturalness of the area and the existence of severe weather refuges. Bird surveys undertaken or commissioned by my Department, together with information from Birdwatch Ireland and other sources, underpin the above assessments.
