In the late 70's, early 80's, the bear kill in TN was somewhere around 30 bears/yr. There was actually consideration of closing the season. A TWRA working group came up with some plans to make some major changes to try to see if anything could be done to prevent that.
A good friend of mine had completed his research on denning habits of black bears. In it, he found that in a lot of years that females went to their den much earlier than males. By shifting the hunting dates from October and November to December, you could shift the harvest away from females. With their low reproductive potential, it was a major deal. So, those changes were made, and the kill percentage shifted dramatically to the males.
The other major thing they did was work with the USFS to set up bear reserves on both the North and South Cherokee WMA. By not allowing bear hunting in these areas, it provided some refuge from hunting for the bears.
And, Operation Smokey, an undercover investigation with TWRA and the USFWS ended with the arrests of 80+ illegal hunters in TN, NC, and GA in 1988. That operation curtailed SOME of the illegal bear hunting for several years.
All of this together has lead to our modern day bear population and kill. Back when I was working it MANY years ago, I would not have dreamed that it would get to this point. I guess in theory that the bear reserves could be done away with. But, it will take changing the proclamations that set them up. I'm not sure where TWRA and the Forest Service would stand on such changes.
