The wild boar (Sus scrofa), the wild relative of the domestic pig, lives in most of European forests but it's more frequent in our evergreen oak woods. The wild boar eats fruits (mainly acorns in Bages) and roots, bulbs and rhizomes that it digs up with its snout. It can also eat some animals. Like most of mammals it is not easily seen in the forest. It walks in the twilight, while it hides into the dense vegetation during the day. However, it leaves notorious traces of its activity. The most frequent ones are its deep footprints of two open toes on the mood of the puddles of the paths or nearby the pools -as seen in the image in the middle left-, the dig out ground by its snout looking for roots, bulbs, worms or edible mushrooms -as seen in the image middle right from Montserrat- and the worn out woods, usually pines, that the wild boar uses regularly to scratch itself -as seen in the image down-. At the end, these pines loses the bark, they appear as a naked wood on the middle of a stepped ground. Some stuck with mood thick, black hairs proof that is the boar that has caused this serious damage to the tree. Since wolves were extinguished in Catalunya, the only depredators of adult wild boars are men. [photos Jordi Badia (top, middle right and down) and Florenci Vallès (middle left)]
