Native or non native doesn't really matter when there are so many people that either make a living off the game in question or have a supplemental income from them. In order for them to continue this and create a residual income they must ensure survival of their assets. Considering the best pig populations seem to be on private lands I don't think it would make a difference if they opened it up to eliminate them.
It does make a huge difference. As it is right now if I go to the sale yard and by some pigs and I free ranged them on my property if I want to harvest them or there young in a year or two, I would have to have by tag. This is not the case with any other domestic. Also a big question for me is why is there a plane out over private property looking for hog hunters at night? It is legal to hunt hogs at night in Nevada county as well as many countys in this state with a depredation permit, which we dont know weather or not they have one.
As far as the other responces on hunter ethics. These guys are trying to thin the hog load on there property. They are bending the rules and breaking a law or two. If I see a hog in my calving field, it wont be alive long. In the course of a day we as people break many laws. It is funny people say they give "hunters a bad name." I think that the state needs to reevaluate it's prioritys. We have lost trout plants, because they are non-native. They are discusing eliminating striper regulations, and limits because they are non-native. We lowered funding on salmon hatcherys, yet we can aford to send out planes with night vision to catch people killing hogs on private property in there calving fields...... It was not long ago our state payed guys from Austrailia to kill hogs to preserve the kit fox, and now we are calling for guys to be sent to jail over two hogs they killed in there calving fields.
