The increased nature conservation awareness in the second half of the 20th century initiated nature conservation movements and founding of international nature conservation organizations. Various international conventions were adopted, aimed at biodiversity conservation. In order to achieve these objectives, the EU adopted the Birds and Habitats Directives. The article describes the designation of Natura 2000 network on the basis of both European directives. The procedure of designating the Natura 2000 sites in Slovenia, including biogeographic seminars, is described in detail. The data on changes in the Decree on special protection areas (Natura 2000 sites) that concern the number and surface area of Natura 2000 sites as well as the number of qualifying species and habitat types within the sites are gathered herewith.

Povečana naravovarstvena zavest ljudi v drugi polovici 20. stoletja je sprožila naravovarstvena gibanja in ustanavljanje mednarodnih naravovarstvenih organizacij. Sprejete so bile mednarodne konvencije, namenjene ohranjanju biotske raznovrstnosti. Za uresničevanje ciljev teh konvencij je Evropska unija sprejela Direktivo o pticah in Direktivo o habitatih. Članek opisuje določitev omrežja Natura 2000 na podlagi obeh evropskih direktiv. Podrobno je opisan postopek določitve območij Natura 2000 v Sloveniji, vključno z biogeografskimi seminarji. Zbrani so podatki o spremembah Uredbe o posebnih varstvenih območjih (območjih Natura 2000), ki zadevajo število in površino območij Natura 2000 ter število kvalifikacijskih vrst in habitatnih tipov v območjih.
