The Conservation (Natural Habitats, &c.) Regulations 1994 (SI 1994/2716) implement the terms of the Directive in Scotland, England and Wales. 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). For example, the Broadland SPA in eastern England is a conglomeration of some 28 SSSIs. SPAs may extend below low tide into the sea, and for these areas SSSI notification is not possible. In Scotland, some SPAs have been classified without any underpinning designation by SSSI.[clarification needed]
Special Protection Areas for Birds in Poland are called OSOPs (Polish: Obszar Specjalnej Ochrony Ptaków). As of 2005, there were 72 OSOP Areas designated as such.
In the Netherlands
In the Netherlands, Special Protection Areas for birds are called Vogelrichtlijngebied.
The Spanish term is ZEPA.
There were 658 Spanish sites as at 2021.[2]
In the Czech Republic
The Czech Republic uses the term Ptačí oblast (PO, bird area) for SPAs. Between 2004 and 2009, 41 bird areas were declared by government directives.[3] They cover 9% of the state area.
