Together with Special Areas of Conservation ( SACs ), the SPAs form a network of protected sites across the EU, called Natura 2000.

In Great Britain, SPAs ( and SACs ) designated on land or in the intertidal area are normally also notified as Sites of Special Scientific Interest ( SSSIs ), and in Northern Ireland as Areas of Special Scientific Interest ( ASSIs ).

The SPAs are designated directly by each EU Member State, while the SACs follow a more elaborated process: each EU Member State must compile a list of the best wildlife areas containing the habitats and species listed in the Habitats Directive ; this list must then be submitted to the European Commission, after which an evaluation and selection process on European level will take place in order to become a Natura 2000 site.
