I saw multiple dead boar carcasses or remains along parts of the VF in eastern France and the forested areas of Italy. If one hikes long enough in the right places, one will see more than one dead boar along the trail. There is a concerted effort in some forested areas to remove them entirely as they are a very destructive specie to native plants and some other wildlife. They are also vectors for swine flu and other diseases.
Note: I grew up in a family where hunting wild boar was part of life in my father's family (less so in ours, but still common). There were hunting seasons and tags/permits had to be acquired, but the family hunted mostly for food, not sport. This was in the mountains of the Western USA and we did not know that hunting boar (among other things) was anything but ordinary.
Fast forward some 60+ years: Walking the VF in early May, I encountered a wild sow and piglets in a forest just south of Viterbo (on the ancient medieval VF route over the Vico volcano). The encounter was brief, as I immediately stopped when I heard the squealing of piglets, located the approximate location/direction where it was, found a suitable large rock and nearby tree to scale if necessary, then located the sow moving slowly through the underbrush parallel to me about 40 feet away. We made brief eye contact when she came to a small clearing about 30 paces ahead of me and I made some noise and clanked my hiking poles on the rocks beside me, but otherwise did not move. I had unclipped my pack so I could shed it to climb the nearby tree if necessary, but the sow gave a snort and grunt and turned away and took the squealing piglets with her. When my adrenaline rush subsided, I resumed hiking, but was singing (loudly and badly) and making a lot of noise for the next couple of miles. I encountered a logging crew a couple of miles on down the trail and they told me to keep my eyes open because there was a lot of pig scat and other signs of activity in the area. I was quite relieved to get back to tarmac and farmland just a couple more miles down the trail.
Side note: we now live in Kona on the Big Island of Hawai'i for five months each year and there is unlimited hunting of boar there as the pigs have destroyed entire eco-systems on the island by uprooting native plants and trees in search of food. The local government there has declared boar an invasive species and allows/encourages an unlimited kill of them year around. Parts of Volcano National Park, near Kilauea, are entirely fenced for many miles along the perimeter to keep boar out of the Park, preserving vital nesting grounds for Nene, the State Bird (and also a threatened specie) as well as certain plant types that only grow in the area around Kilauea. Pigs are a problem everywhere when they become feral/wild.
