These are photos from the neighbouring land I stalk. The owner asked me to have a look and see if I could determine what was causing the damage. The turf appears to be folded over and in some cases rolled up. Some is fresh some old by looking at how dead the grass is that has been folded over and the texture of the soil exposed. There are no machines on the ground. First thought is badgers but is covering an area of 1/2 acre. Never seen Boar in the area and very few signs of tracks or claws apart from the odd slot on the soft ground.
