I can tell you that coyotes, and bobcats...have a big impact on the deer, turkey, quail, etc...population...but you might not understand that.
And I've not even mentioned feral hogs.
As for the rest of your post...you make me LOL...noob.
Regarding predators, even Mountain Lions, significantly hurting deer,turkey or quail populations, that's bogus. By far poaches have a much bigger impact. Are you for shooting poachers? From what I hear from my friends in Oklahoma, lots of Okies have a reputation for pouching. From an ethical hunter's perspective,there is a very narrow and easily crossed line between poaching game and shooting any animal just for the fun of it.
Can't say for Oklahoma, but in Texas deer and turkey are flourishing, the quail's biggest problem is Imported Fire Ants. Hope you are lucky enough to not have them yet.
