I am a doe hunter, so I am going to hunt does, as long as there are permits and deer to chase. I will self-regulate, in that when the population gets bad enough that I cannot have a reasonable expectation of filling a tag, I won't waste my money. I am definitely not going to buy a tag, just to keep one more deer from getting killed.
It bothers me to see states such as Montana and Wyoming complain about deer numbers and continue to offer antlerless, or either-sex permits. If you add hunter mortality onto the doe population along with the predators and bad winters, you have a recipe for a tough recovery.
I am fortunate to live where I do, as far as killing does to fill the freezer. That being said, Game and Parks started really regulating the take of mule deer in certain areas due to declining populations. It has worked and the deer are coming back very strongly. They have superb habitat with lots of food and few winter issues, which really helps, also. There are a couple places where many of the deer winter and the farmers would like them gone. Game and Parks is smart enough not to issue depredation permits to those people, as that is where a good portion of the population of mule deer in that area winters. They do allow hunting, though, so that is not a problem.
I will never waste my gas to drive to Montana, as the permit fees etc., are out of control and the animals are dwindling. I guess that is self-regulation on my part. I will go to Wyoming for elk (cuz I can't draw a Nebraska tag), but I will just continue killing my 10-30 deer a year here until they decide that can no longer do it.
