Sažetak

Amphibians are a significantly and globally threatened group of vertebrates. In the European context, this particularly refers to the fire salamander (Salamandra salamandra Linnaeus, 1758), assessed as a vulnerable species due to a decreasing population trend. Threats affecting the population include climate change, habitat fragmentation due to road and infrastructure construction, and the fungal disease Bsal. Roadkill of amphibians during migration cycles also affects their abundance. In Plitvice Lakes National Park we monitored the number of fire salamander individuals on the road during spring and autumn migrations in 2023, including animals captured in passive traps along eight sections, and those found road-killed. Seven amphibian and one reptile species were recorded during this research. Selected mitigation measures to prevent fire salamander roadkill with the installation of temporary fences with pitfalls and funnel traps, singled out certain sections as more active, providing insight into the sex ratio of individuals and recording the number of casualties. The fire salamander was the most represented amphibian with 170 individuals captured in passive traps, 36 counted alive on the road, and 50 road-killed. Using individual recognition software Amphibian and Reptile Wildbook, 93.81% of individuals were confirmed to be captured only once during the study period. Through ongoing activity, additional data will be gathered on the number of migration routes, including road-killed individuals opposite the temporary fences, identifying new critical points, and documenting roadkills.
