One further comment is that is the USA wildlife belongs to the nation and if you have a valid tag/permit you may hunt it. There are restrictions regarding species, bag limits and seasons as well as posted land. I think that covers it.
In South Africa the game belongs to the landowner. That may be a farmer who does not even know there is a record book Kudu on his farm but if you shoot it, that's poaching. Certain species such as dangerous, endangered or exotic animals like lion,wild dog, elephant, Rhino, tigers come under closer limitations regarding ownership. The core difference is that the landowner can dispose of 'stock' at his discretion, and invite others to help him. This is where the ugly practice of lion farming arose, lions are not endangered but are considered 'dangerous' and in many areas are declared 'problem animals' in terms of the law. A problem animal must be destroyed unless it is kept under certain conditions, like a twelve foot electric fence. Have that and if you need to 'destroy' the animal you can sell the work to anyone you like...
If you are a hunter you need a valid hunting licence and permission from the farmer. The licence will describe HOW and WHAT you may hunt under the act, eg rifle, bow, with dogs etc.If you transport game or game products you need permits from the state/provincial authorities and a form from the farmer stating that the game was legally aquired. Now the methods of hunting are set down in regulations that mostly start with what you are not allowed to do and then comes a list if conditions under which you may hunt...The base assumption is that you are not allowed to..except if you fufill a set of requirements.
It seems ponderous but I believe it has its origins in the old British notion of royal game and was intended to prevent the wholesale destruction of species by unscrupulous exploitation of game in open land. By giving game a value it has encouraged farmers to look after it. This has been a remarkable success story, there is now more land under game and more individual animals alive to day than there were 120 years ago, in the 'golden age of hunting in SA'! Amazing to think. South Africa can boast of hunters having multiple shot opportunities in good hunting conditions, they are happy and the farmers are happy.
I had the absolute gift of a job that took me to many game reserves and hunting farms over a period of four years and I was amazed at the care and expense farmers went to to ensure the health of their animals and farms. There were very few bad operations I am glad to report, although we saw a few masquerading as 'research or rehabilitation centres' that I doubt were anything of the sort.
