What are the Protected Natural Areas and Natura 2000 sites?

The function of Natural Protected Areas (AA.NN.PP.)  is to maintain the ecological balance of a particular place, increasing biodiversity.
In 1992, the International Union for Conservation of Nature (IUCN), a non-governmental organization that plays a role of coordination between different organizations in environmental matters, defines a protected area as "strip of land, more or less extended, where the guidelines, and rules for a correct use of the environment by man may be applied and where it is possible to safeguard and experiment methods, forms and technologies suited to manage in a balanced way with other living species (plant and animal) the resources the planet. "

Natura 2000  is a network of nature protection areas established under the EU Habitats Directive of 1992, whose main objective is the protection of natural areas and wildlife in Europe. The Sites of Community Importance (SCI) selected for each biogeographical region, together with the Special Protection Areas (ZPS) designated under the Birds Directive, constitute Natura 2000 network that covers all 27 Member States of the EU.
