I. Introduction
The conflict between wild animals and humans has recently focused on some species such as large carnivores in Africa and America [1], and the wolf (Canis lupus), the bear (Ursus arctos) and the lynx (Lynx lynx) in Europe [2]–[3]. In particular, the negative impact attributed to these animals is the predations on domestic livestock. In many European countries, however, the damage to crops and agriculture in general is attributed to the wild boar [4]. Among the wild animals, the wild boar is the one best known by the public opinion and whose presence is the most controversial due to its association with the mentioned damages to agriculture [4]–[8], road accidents [9]–[10] and, in recent years, to invasion of cities [11]. In the 21st century, i.e. the era defined by “social networks”, in the web spaces dedicated to animals the wild boars, although appearing strongly competitive with the most loved dogs and cats, seem anyway to be hated due to their unquantified population explosion [12]–[13]. Since ancient times wild boar has always had a close relationship with man, and it is currently considered one of the most invasive species on the planet after man [14].
