The National Park boast an exceptional diversity of habitats, including nearly all types of terrestrial and aquatic habitats present in the region. It is precisely this diversity of habitats that supports the great diversity of amphibian and reptile species in the area.
The “Research on Amphibians and Reptiles in the Plitvice Lakes National Park Area between 2021 and 2023” project identified 12 amphibian species and 13 reptile species. The research was conducted by the Hyla Association in cooperation with the Park’s Professional Service Department.
Three of these species are target species for the Park area: the Horvath’s rock lizard (Iberolacerta horvathi), the black salamander (Salamandra atra), and the Italian crested newt (Triturus carnifex).

The research aimed to document the amphibian and reptile fauna in the Park, assess the population status of the recorded species and identify the threats they face.
Because of their biological traits, they are particularly vulnerable to road accidents—one of the leading threats to their survival—along with pollution, habitat degradation and loss, as well as disease.
