Pelodytes caucasicus inhabits Turkey, Georgia, Abkhazia, South Ossetia, Azerbaijan, and six regions of Russia (226 localities). The forest cutting strongly threatens its populations. Therefore, the frog is listed in Red Data Books of Georgia, South Ossetia, Azerbaijan, and the Russian Federation. Additional factors influencing the decline of P. caucasicus populations are destruction and contamination of suitable water bodies, clearing of forests from fallen trees, destroying of litter, mortality on roads, and preying by the introduced North American raccoon. Using of MaxEnt, we developed a species distribution model based on climate, landscape and land cover data to estimate the potential distribution range, ecological preferences and conservation status of P. caucasicus. Two precipitation parameters, annual precipitation and precipitation seasonality, had the highest contribution percentage to the model (52% and 11% respectively). As a rule, suitable habitats for the species located in woodland mountain areas with annual precipitation ranged from 513 mm to 2376 mm. Drier regions to the north and south of the Caucasus limit its distribution.
