The aim of the thesis was to further explore the habitat requirements of lean frog (Rana dalmatina). Data collection was conducted in 2007 to 2010 and 2015, a total of 27 locations Hornojiřetínské dump. Were examined factors such as the depth at which they are placed brood, the distance between the clutch, clutches distance from the shore, the location of each type clutches, or whether they are placed in the littoral or not. Furthermore, the slope of the banks surveyed sites and level of insolation. For comparison, if the total number of broods on the site may or may not affect the minimum distance between the clutch, was used Mann Whitney nonparametric test. From the results it can be assumed that the agile frog prefers for laying clutches least partially sunlit areas with plenty of littoral vegetation and gentle slope shores. Depth shallower reservoirs prefers, however, requires the presence of deeper parts of the winter. From the results of a Mann-Whitney non-parametric test in this case is not clearly confirm that the total number of clutches on the location somehow significantly affect distances closest neighboring broods, respectively, that the higher the number of males in the location dwindled defended territory of each of them, and vice versa.
