Natura 2000 is a network of protected areas designated by the Member states of the European Union on their territory according to common principles. The aim of this network is to guarantee protection of species and habitats, which are most vulnerable, threatened, or have a limited distribution (endemic).
The designation of Natura 2000 Sites is prescribed by the Council Directive 2009/147/EC on the conservation of wild birds (Bird Directive) and the Council Directive 92/43/EEC on the conservation of natural habitats and of wild flora (Habitats Directive).
Special Protection Areas (SPA) are designated according to the Bird Directive for the protection of bird species. Sites of Community Importance (SCI) are designated according to the Habitats Directive for species and habitat protection. Both types of Sites form Natura 2000 network.
