Crop damage by wildlife is a frequent source of human-wildlife conflict. Understanding which factors increase the risk of damage is crucial to the development of effective management strategies. The aims of this study were to provide a general description of agricultural damage caused by wild boar Sus scrofa meridionalis over a 7-year period in North-eastern Sardinia (Mediterranean Italy), and to formulate a predictive model of damage risk. We recorded a total of 221 cases of wild boar damage, with economic losses amounting to 483,982 Euros. Damage events mostly involved vineyards, meadows and oat fields, and were characterized by a peak incidence in summer and early autumn, and a minimum in spring. Damaged fields were characterized by an increasing presence of permanent crops, a decreasing presence of woodlands, maquis and urban areas, and a reduced distance from shelter areas (forests and shrublands). The analysis of spatiotemporal variation of boar-induced damage and the identification of factors that augment the risk of damage provides essential information for contributing to the development of a more effective plan for managing wild boar populations.
