In the diploma thesis we analyzed forestry accidents based on intervention and accident reporting information system (SPIN) for the 2007-2018 period. The purpose of the research was to present the SPIN application, the operation of the application and the method of data collection, and above all to analyze the multi-annual statistics on forestry accidents in it. We reviewed calls to the crisis center and extracted calls describing an accident while working in the forest. 563 accidents were analyzed. The results show that for 14 % of injured people accidents were fatal, 7 % were severely injured and for the rest, severity of the injury is unknown. The number of all incidents depends heavily on felling and the area of private forests. Accidents in the time analysis are comparable with the previous research, as well as in the damaged parts of the body and causes, sources and types of the accident. SPIN data is more useful for monitoring the timing of accidents, data on damaged parts and causes and sources, and less reliable for estimating the number of accidents in terms of the severity and reducing measures.
