The main goal of the thesis was to evaluate the most commonly used steps in the case of prevention of killing and injuring wild animals during agricultural management. The another goal was to choose optimal technique, verify chosen technique (for the prevention of harming wild animals) practice and create a functioning methodology for it afterwards. The used technique was the searching for the wild life by a drone equipped with a thermal camera. There were three flights done with a drone during which the visibility of wild animals via a thermal camera was examinated. We found that the rate of successful identification of the animals is dependent on the drone flight height and on the temperature of scanned area. We also found that monitoring is not applicable when a morning fog is present. Monitoring also showed that optimal daytime for searching for animals is before the sunrise. With drone we mostly managed to detect deer, but also pheasants and hares.
