I personally feel that if the trespass regulations were enough of a deterrent, that would be enough, because you would be able to prevent the act, and if it occurred, you would be able to react quickly and contain it. The issue is that if you cannot react quickly and contain it or prevent it, then that introduces the concept of a risk to biosecurity. That is where I see the addition being protective.
