Arguing that big game populations need to be maintained at a unnatural level, and that man should be the decider on numbers is doomed to failure.
Basically your taking a nonscientific approach to game management.
This will be easy pickins for the anti's in court.
FYI elk were reintroduced into Oregon in the early 1900's, they had been completely wiped out, not by predators, but rather by the hand of man.
Want higher big game populations? Then lobby to end private grazing on public land.
