I was thinking the same thing. Except I was thinking about Coyotes picking off the young ones. Best estimate 4-5 thousand Cougars in California, 164,000 square miles.

Unless Hogs have an abundant food supply, good cover, water and they aren't hunted much they aren't likely to settle in one local area. But generally they are Gypsies. The food runs out, they get hunted or they just get antsy and they move on. Not uncommon for them to cover ten miles a night when they are on the move. The ones that get too predictable are the first to die. After around three years old they get way smart. The juveniles not so smart. I watched one old Sow lead the sounder on a zig zag course, out of rifle range of half a dozen shooting towers and high seats, I was amazed.

Near my lease there are other leases in the area and bordering mine. We tip each other off when the Hogs are around. One guy harvest out one or two and they are likely to pop up on the next lease. We also harvest out the adolescent 1-2 year olds, typically you are only going to get one or two chances before they move on, we take the potential breeders 1-2 year olds as a priority. And tend to leave the largest Sows because they are the memory of the sounder and make them somewhat predictable.

I wonder if a newspaper ad and/or social media would help. Hog spotters call XXXXXXXXX. Why not? Everybody and their cousin are posting about lost dogs and Cats.
