A quick scroll through Montana records books and I can see two things not much is in the book recently from either side of the state and western Montana dominates overall. Validates what I have seen in pictures recently as well. Give a whitetail cover and they will survive.
Don't disagree to an extent, but where I hunt, you could eliminate whitetail with enough pressure and they almost did it. I would say reduced the population by 60-70% in 4 years of OTC b-tags.
Recovery has been frightfully slow even though they pretty much quit b-tags. When you shoot a population down that low, combined with increased predator numbers, and still a fair bit of human hunting, they just don't bounce back. Its taken more than decade and the population still is maybe 65% of what it was in 2006.
Shot these deer in 2003-2006
The night that I shot this buck, there were 3 bucks in this size class fighting and running around on a hillside along with a bunch of does and several smaller bucks.
Killed this one at 1 PM and was the 22nd 4x4 or better buck I'd seen THAT DAY. Was also about year 2 into the unlimited b-tags.
By 2008-2009, I was lucky to see 22 4x4 or better bucks the entire season. A bunch of guys started hunting it due to the b-tag availability and they would pound on a buck if they saw one as well.
Its been a long slow grind to get back to even fair hunting.
But, hey what do I know I've only been hunting the same area since 1979, my family for 40 years prior to that.
