UNESCO's tentative or provisional list (the list of potential sites) serves as an inventory of properties located within a country’s territory, which are deemed suitable for inclusion on the UNESCO World Heritage List. Member states include properties on their Tentative Lists that they consider to be cultural and/or natural heritage of outstanding universal value, which they intend to nominate in the coming years. Nominations for the World Heritage List are accepted only if the site has previously been included on the tentative list. The natural and historical area of Blidinje has been on UNESCO's tentative list since December 11, 2007. Blidinje is recognized for its exceptional natural beauty and ecological value. These areas are acknowledged for their natural resources, unique landscapes, biodiversity, and cultural significance. Blidinje is renowned for its rich flora and fauna, including rare and endemic species, as well as significant ecosystems like mountain pastures and forest communities. These characteristics make Blidinje worthy of global protection and preservation.
