Amphibians are commonly viewed as indicators of regional environmental health because of their dual life cycle, sensitivity to environmental changes, and dependence on water. In order to clarify species ranges and identify of factors influencing distribution, we surveyed 5 sites to known systematic and population structure and describes patterns of geographic variation in population structure and describes patterns of geographic variation in population structure and describes patterns of geographic variation in sampling areas since Februarys to June 2013, 105 specimens were collected from different habitats of Arak county. Sampling carried out by hand and also morphology and morphometry, studies to determine of the status of the intra-were measured and all the specimens were identified using recent recognition keys for anuran. In total, 4 species belong to 4 Genera and 3 Families of Amphibians including: Bufo viridis from Bufonidae, Rana ridibunda from Ranaidae, and Hyla savignyi from Hylidae, were collected, studied and identified that Rana cameraniand and Hyla savignyi were reported for the first time from this area.
