I'd say badgers but have a look for tracks.
Looks exactly like what had been a beautifully manicured 100m range at Pirbright/Ash when my shooting team turned up to practice the SMG (start at 100m, forward to 75m, 50m, then 25m). Range warden was very unhappy I intended to walk the guys straight down their lanes from firing point to firing point with the weapons made safe - as per the competition rules. He suggested unloading everyone, filing them all off the point, walking down the side then filing back onto the next point etc. Apparently, he expected us to fall over the bumpy bits and spray each other and most of the surrounding countryside with full auto 9mm Parabellum.
I suggested he go and sit in his range hut, drink his coffee and read his Sun/Playboy.
