I agre with Buddy. But there is one thing you can do. That is to lower the impact you have for that area you are watching. Reduce the amount of scent you leave when going in and out and keep a low profile by going in where they do not (don't walk along their trail and keep as scent free as possible), go in when they aren't around and cannot see you, keep quiet etc.
I doubt that one pass by a shotgunner is going to boot them out but it may boot some out. That years deer is going to take more than a 6 year old buck. One things for sure they won't hang out where you park your vehicle because of the noise and scent you leave. They say that there are many bucks in the woods that have seen man but have never been seen by human eyes. I believe that to be true. One push and the odd old wise surviving buck is probably gone from your grasp because it either goes somewhere else or it will turn nocturnal.
As Buddy said, stay out of thier sancutary or bedroom and you can milk the area like a cow. No question that some are better survivors than the others. Wheather or not its is intellegence or just better programing is something we'll never know. Its like waterfowl hunting. We never hunt their pond/bedroom until the few days. The last few hunts are a slaughter but they repopluate the pond next year. Maybe not all of them come back but the same numbers do.
