Herpetofauna is of interest in protected areas because of the large number of protected species. We studied the herpetofauna of Cozia National Park (CNP) between 2016 and 2018. CNP is situated in the central part of the Southern Romanian Carpathians. We recorded 10 species of amphibian (Salamandra salamandra, Triturus cristatus, Lissotriton vulgaris, Bombina variegata, Hyla arborea, Bufo bufo, Bufotes viridis, Pelophylax ridibundus, Rana dalmatina and R. temporaria), and 11 reptile species (Lacerta agilis, L. viridis, Podarcis muralis, Darevskia praticola, Zootoca vivipara, Anguis colchica, Natrix natrix, N. tessellata, Coronella austriaca, Zamenis longissimus and Vipera ammodytes). Reptiles dominate in number of species, number of individuals and distribution records. CNP is situated at the northern limit of the distribution range of some of these reptiles, notably D. praticola and V. ammodytes. Mountain species associated with a colder, moist climate are very rare or even absent. Zootoca vivipara is restricted to the highest areas of Mount Cozia, above 1 350 m. Although mountain species are well represented in other Carpathian regions, the warmer, drier climate of CNP and its surroundings has limited their distribution in the area, pushing Z. vivipara to higher and higher altitudes. Lacerta agilis is syntopic with all the other lizard species. In some areas, as many as four lizard species cohabitate. The distribution of the herpetofauna in CNP has been negatively influenced by past human activity. The dams on the River Olt have favoured species related to large, stagnant bodies of water, in a region where such habitats were naturally missing. In addition, massive deforestation has decreased the abundance of herpetofauna in many areas of CNP.
