The difficulties in broaching the environmental management of the wolf species have increased economic conflicts, mainly with livestock farmers. To facilitate and pacify the debate, an assessment of the risk of wolf attacks on livestock farms in Umbria’s municipalities needed to be carried out. For this assessment, AHPSort II, a new multi-criteria sorting method for a large number of alternatives, has been developed. This is used for sorting the alternatives into predefined, ordered risk categories. It requires far fewer comparisons than its predecessor, AHPSort. This sorting method can be applied to different environmental problems that have a large number of alternatives.
