Resumen

Currently the problem of the effects of the road network and traffic on the amphibians and reptiles in Bulgaria is poorly studied. During the period March 2002 - March 2004 in the Buffer Zone of Biosphere Reserve “Srebarna” (NE Bulgaria) were built two anti-fire roads from the eastern and western side of the lake in area of grasslands of semi-steppe type, typical for north-eastern Bulgaria. The aim of the constructed roads is to provide access for fire vehicles to areas in and around the reserve. The current study aims to provide data on the impact of road traffic and the newly constructed road network and another previously existing road on the amphibians and reptiles inhabiting the buffer zone of the biosphere reserve “Srebarna”. For the entire period of study in the three studied road sections a total of 15 dead specimens of amphibians belonging to 4 species (Bombina bombina, Hyla arborea, Bufo bufo, Bufo viridis) and 70 dead specimens of reptiles belonging to 8 species (Emys orbicularis, Ablepharus kitaibelii, Lacerta viridis, Podarcis tauricus, Podarcis muralis, Natrix natrix, Coronella austriaca and Dolichophis caspius) were recorded. Several “hot spots”, where most cadavers were recorded are well described and possible conservation measures are discussed.
