It's not hunting, it's pest eradication.
The two concepts are not necessarily mutually exclusive and by law, you need a hunting license (unless you are the landowner). You may not want to call it hunting, but what folks consider to be "hunting" varies widely and it seems that more often than not, it seems that many hunters think that anything that eases the process makes it not hunting. I can recall some of the old gun rag articles on the use of telescopic sights for hunting making hunting not hunting, LOL. Hunting a baited area isn't hunting, but hunting a food plot planted to attract animals is, LOL.
This law isn't about hunting, however. It is about allowing the commercialization of selling/renting seats on helicopters for the process of taking hogs.
Whether or not the hunters wish to engage in eradication processes or in an attempt to take trophy hogs is another matter.
