Perhaps this is not practical, but could a company produce a set of medium range drones that use ML to identify cow vs. wolf vs. human vs. vehicle and thus report which section of their range has a wolf or human poacher? A pair of drones patrols the perimeter while a pair charge up, then they swap places automatically and run 24/7. Perhaps these could even report if a rancher or hiker is laying on the ground (injury, medical issue) and send footage to the ranch owners phone with coordinates? Is this feasible?
