 abstract={Studies on amphibians of permanent water bodies and marshes in the Wawer district of Warsaw were carried out in the spring of 2007. This terrain is situated on the right bank of the Vistula River, and is one of the least urbanized areas of the city. In this study, species composition, frequency of occurrence and number of individuals on breeding sites were determined. Surprisingly, only six amphibian species were found, which was two times lower than found during previous research in the left bank area of Warsaw. The most common species occurring in Wawer were: moor frog \{Rana arvalis) and common toad \{Bufo bufo). Only 69.2 % of permanent water bodies were inhabited by any amphibian species. To enable future comparative studies to be made on the impact of urban development and increased human activity on local amphibian populations, the precise locality of breeding sites were provided.},
