I have just returned to the US after several years in Germany, as well as hunting in Poland. This is my experience:
Re: teaching LtCol Cooper's rules, I always taught them in my classes. I cannot speak for others.
I have stalked and used the high seat in Poland. I have used the high seat and been on driven hunts in Germany.
Re: ASP (Afrikan Schweinpest, or African Swine Flu. It's a problem everywhere, even if it hasn't been found yet. Germany does not yet have a problem with it, but it has the potential of destroying the domesticated pig population as well. Hence the warning signs at the rest areas all along the Autobahn. Additionally, even in the high times of Covid lockdowns and curfews, I carried a letter from the Forstamt declaring that boar hunting was considered essential, and if I was out at night hunting, the curfew did not apply.
Hunting pigs is normally done at night, because the pigs are normally nocturnal. Night vision of some sort is encouraged, even if it's just a green flashlight and a large objective scope. There are two reasons for this: The first is Weidgerechtikeit, or respect for the animals. That is you need to see to ensure a good hit, which limits wounding animals. Night vision may not seem "fair", but pigs are becoming a problem, and while "culling" isn't what it's called, it is what's being encouraged. This encouragement has led to loosening restrictions on night vision devices. And, let's be honest: I'm using a high-powered repeating rifle using smokeless powder, premium bullets, and a suppressor. We're a bit past the spear with a flint point age, aren't we?
Driven hunts are normally scheduled towards the end of the season. The reason is simple: At the beginning of the season, the authorities will determine the number of animals the area can support, and how many must be removed. If the "goal" is not reached towards the end of the season, a driven hunt is used to try and increase opportunities to thin the herd.
As far as "over bait", from the German perspective, this is not "Weidegerechtikeit". At the same time, farmers need to be protected from damage. So plots are placed to lure the boars from the farmer's field... but one should hunt some slight distance from them.
Because boar are normally hunted at night, it is good to add them to another hunt. You can set a day hunt for roe or stag, and then boar at night. I recommend Poland as less expensive.
