The dinaric calcareous silver fir forests are an endemic vegetation type of the littoral Dinaric Alps, located in the Dinaric Mountains mixed forests ecoregion in southeastern Europe. Pure stands of dinaric calcareous silver fir (Abies alba) forests appear on limestone escarpments in the montane zones of Orjen, Velebit, Biokovo and Prenj. They comprise one of the most interesting formations of Balkan vegetation types as the forests bear several rare plants and are of striking beauty. As a highly endemic and rare vegetation type of the dinarids, it needs protection.
