The changes in the occurrence of amphibian were monitored in the region of Novohradske mountains and in its foothills in seasons 2009-2010. Observation was focused on the presence of 11 species of amphibian in 31 selected locations. The results confirmed a significant decrease in the frequency of the species: Smooth Newt (Lissotriton vulgaris), Alpine Newt (Mesotriton alpestris), Warty Newt (Triturus cristatus) and synklepton Pelophylax synklepton esculentus. A mild decrease by European Tree Frog (Hyla arborea) and Common Spadefood (Pelobates fuscus). The balanced condition was found out by Fired Bellied Toad (Bombina bombina) and Yellow Bellied Toad (Bombina variegata), Common Toad (Bufo bufo), Grass Frog (Rana temporaria), Moor Frog (Rana arvalis) and Agile Frog (Rana dalmatina). Species were determined according to morphological characters. Observed data were compared with results of surveys of monitored sites from years 1999-2004.
