I'd say give it awhile, he is likely to be over run. Some of the Lakes not too far north of him had some serious hogs issues, mostly in the State and National forest. They hired trappers.

Santa Cruz mountains had Hog issues for awhile.

I hunt mostly the south, the issue there is water and the drought has dried up a lot of what is available. I hunted Hogs near Santa Barbara, south of Lake Cachuma. Areas of chaparral out their that are really huge. I have no doubt there are still Hogs out there.

It seems to be like Whack a Mole, they get hunted, trapped or run out of one area and pop up someplace else. Been that way since the 70's. It wasn't long ago the central valley had an issue with Hogs carrying disease into there vegetable farms, a lot of people got sick.
