Special Protection Areas (SPAs) are strictly protected sites classified in accordance with Article 4 of the EC Directive on the conservation of wild birds, also known as the Birds Directive, which came into force in April 1979. They are classified for rare and vulnerable birds, listed in Annex I to the Birds Directive, and for regularly occurring migratory species.
In 2013 there were 17 classified Special Protection Areas wholly within Wales (covering 123,058 ha). Of these, 4 are located within Snowdonia totalling 24,301.5ha.
