Similarly to the last few years, also in 2013 a mobile seasonal barrier/fence 565 meters in length was installed to prevent amphibians from entering a road around the Souš Water Reservoir (the Jizerské hory/Jizera Mts., northern Bohemia).
All traps for amphibian capturing were carefully checked twice a day and cleaned by the trained staff. After determining species and sex, the captured animal were safely released in the direction of their original movement and migration.
