The localization of Rana temporaria and R. arvalis spawning sites with regard to territory distribution of leading environmental factors (water supply, vegetation, micro- and macro- relief) on the Kizhi Island has been investigated using GIS–technology and component analysis. Spawn layings of R. temporaria are diffusively spread on the territory because spawn is preferably laid in the large pools of water from melted snow. Spawning of R. arvalis takes place in zones of spring waterlogging of mires by lacustrine water and therefore is attached to a narrow lakeside zone of nearshore mires.
