The grey wolf (Canis lupus) in Slovenia causes damage to cattle, which has not yet been studied in greater detail. The aim of this undergraduate thesis was to analyze damage inflicted by wolves on cattle in Slovenia between 2009 and 2022. The data used in the study were obtained from the Slovenia Forest Service and the competent ministry (currently the Ministry of the Environment and Spatial Planning). The analysis focused on the age, sex, and breed characteristics of the affected cattle, as well as the temporal and spatial distribution of the damage cases. For the age-related analysis, animals were categorized into distinct age classes. A relative probability index of attack for each age category was introduced, revealing that younger cattle have a significantly higher likelihood of being affected by wolf predation compared to older individuals. Data analyses demonstrated that, in damage cases recorded, a higher number of females than males were preyed upon across all age categories. An increasing trend in the number of attacks and animals attacked was observed during the study period, peaking in 2019, after which the number of damage cases began to decline. Furthermore, differences in the frequency of damage events were observed among cattle breeds. An analysis of compensation claims for property damage showed that the average claimed compensation per animal increased with higher age categories over the study period (2019–2022). A large proportion of the damage was concentrated in the areas around Postojna and Slavnik, with damage recurring regularly at some locations. The results of this study enabled us to provide guidelines for reducing the number of damage cases, which focus primarily on protection of youngest calves on pastures with recurring damages. These could contribute to better coexistence between humans and wolves.
