The Meledic Plateau Protected Area has a double conservation status: protected natural area of national interest (code 2.267) and Natura 2000 site (ROSCI0199). The Protected Natural Area of National Interest Meledic Plateau is a mixed reserve of geological, speleological, zoological and botanical importance. The Natura 2000 Site Meledic Plateau was established for the conservation of a priority habitat and an invertebrate species – the lepidopteran Lycaena dispar. An inventory of the terrestrial invertebrate species was conducted, within the scientific studies that underlay the elaboration of the Management Plan of this protected area, and three invertebrate species of conservation interest were identified: two species of community interest – Lycaena dispar (the Large Copper Butterfly) and Lucanus cervus (the Stag Beetle), and one species of national interest - Euscorpius carpathicus (the Carpathian Scorpion). The results of the inventory conducted from August 2012 to August 2013 indicate that Lucanus cervus and Euscorpius carpathicus are resident, quite rare and isolated species in the protected area’s perimeter, and Lycaena dispar is a resident, quite rare species, with a dynamic distribution in the Natura 2000 Site Meledic Plateau, determined by the availability of hygrophytic vegetation needed by the larva and adult during the entire period of the species seasonal activity.
