However, in most instances where I see a high percentage of mature bucks with 6 or fewer points, the problem is high-grading of the middle-aged buck population. I have a club client that for many years had a 2 1/2 year-old buck harvest rule. This meant the very best 2 1/2 and 3 1/2 year-old were shot ever year. The bottom end middle-aged bucks were not killed. What this produced was a lot of mature bucks with 6 or fewer points.
I believe this phenomena is exactly what is happening in most areas hunted statewide.
The best yearling bucks, the best 2 1/2s, and the best 3 1/2s simply get killed at a much higher rate than their peers having average to below average antlers.
In "managed" areas, it just happens more with the 2 1/2's & 3 1/2's.
In less "managed" areas, it just happens more with 1 1/2's & 2 1/2's.
But in both areas, surviving results are similar by 4 1/2 & older, in that it's mainly just the below average antlered bucks surviving to maturity
EVERYWHERE bucks are hunted any amount at all.
On QDM areas, 1 1/2-yr-old (yearling) bucks are highly protected, but then highly shot as top-end 2 1/2's or 3 1/2's. In "un-managed" hunting areas, those 6 to 8-point top-antlered yearling bucks get slaughtered, but surprisingly, the number of above averaged mature bucks may end up similar, sometimes even greater in the "un-managed" areas. Go figure that one.
About the only practical way to reduce hunters' antler high-grading is simply to have less buck hunting, and/or less buck hunting with more highly effective weapons. But we like to hunt, and we prefer hunting when the taking of a buck is an option.
Every option has its trade-offs.
Be careful for what you wish.
