The larger issue as far as I’m aware is in setups for hunting tourism. If you have a chunk of land there’s good money in offering guided hog hunts.
But if there are no feral hogs on your property. Well best go get some. Even better if you can toss in some wild boar! So no we have those introduced too.
This is a major part of how they’ve been introduced and started to proliferate in states like NY and PA. It’s less that individual hunters want it closer to home, than people who will pay a lot of money to go hunt somewhere don’t want to go all the way to Texas or Florida.
In concept they’re supposed to be released into penned areas to keep them from becoming established in the area. But pigs are escape artists, even the big commercial pork producers can’t keep them contained. That’s why states with large pig farms are where the problems are biggest and oldest.
I’m not sure sure that’s the best idea. At least in the absence of a good eradication program, because then you’re removing one of the few pressures on populations. And you don’t generally want to protect invasive species. But like I said hunting, and even organized culls, don’t work. At least not for population control.
I know Missouri has a bit more going on than a lot of other states. But they don’t exactly have a ton of resources for it.
Though that also means a lack of resources for regulating and enforcing introductions, outfitters and what have. So you might as well kill the hunting market locally in that case. You can practically accomplish that, where as it just might not be possible to adequately control it otherwise.
This end of it isn’t divorced from the NRA and their pals promotion of FERAL HOGS as justification. There’s a collusion in promoting Hog hunting as this like be all, end all, REAL AMERICAN version of big game hunting. With high dollar specialized equipment, guns, and assorted merch.
So it went from something that was largely pest control, to something European Tourists will pay top dollar to do.
A big part of that was that it was, and in lot of cases still is, unregulated. Because they’re invasive we weren’t limiting people to 3 a season. Or restricting what caliber ammunition or type of weapon. The whens and wheres.
So maybe straight up ban will work better than trying to institute that after the fact. It looks like the Missouri bans are happening in collaboration with Texas, and were pushed by and through the National Parks Service. So it’ll be interesting to see how this plays out, and it does seem to be broader than just Missouri.
