In May 1992, the governments of the
European Communities adopted legislation designed to protect the most seriously threatened
habitats and
species across Europe. The
Habitats Directive complements the
Birds Directive adopted in 1979, and together they make up the Natura 2000 network of protected areas. The Birds Directive requires the establishment of
Special Protection Areas for birds. The Habitats Directive similarly requires
Sites of Community Importance which upon the agreement of the European Commission become
Special Areas of Conservation to be designated for species other than birds, and for habitat types (e.g. particular types of forest, grasslands, wetlands, etc.). Together, Special Protection Areas and Special Areas of Conservation form the Natura 2000 network of protected areas. The Natura 2000 network is the EU contribution to the "
Emerald network" of Areas of Special Conservation Interest set up under the
Bern Convention on the conservation of European wildlife and natural habitats. Natura 2000 is also a key contribution to the Program of Work of Protected Areas of the
Convention on Biological Diversity. As a prerequisite for joining the EU, accession states have to submit proposals for Natura 2000 sites meeting the same criteria as EU member states. Some new member states have large areas which qualify to be protected under the directives, and implementation has not always been simple. The Natura 2000 sites are selected by member states and the European Commission following strictly scientific criteria according to the two directives mentioned above. The Special Protection Areas are designated directly by each
EU member state, while the Special Areas of Conservation follow a more elaborate 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. The Habitats Directive divides the EU territory into
nine biogeographic regions, each with its own ecological coherence. Natura 2000 sites are selected according to the conditions in each biogeographical region; thus selected sites represent species and habitat types under similar natural conditions across a suite of countries. Each Natura 2000 site has a unique identification form called a standard data form. This form is used as a legal reference when assessing the management of the species and habitats through the concept of favourable conservation status. The Natura 2000 Viewer is a tool to explore the network and gives access to every standard data form. ==Current status==
