You are correct. If there are hunters on the private land, there are going to be a lot less than on public land, and they are generally non resident hunters looking for trophy elk, and are not too interested in shooting wolves. Also, it wouldn't take the wolves long to figure out they could miss ALL the hunters by going nocturnal.
All summer, VarmintGuy was claiming that seeing thousands of elk on farmers fields was proof that the wolves have decimated the elk herds. Nobody could seem to convince him that if there are thousands of elk around, they haven't been wiped out.
