From a hunting perspective only do your orchards meet your expectations? I would say they have an impact, but not as big of an impact as good cover. I can set in my blind and see deer eating persimmons, chestnut and other fruit, but I think the deer would be there just for the cover, and there are other natural foods that they would eat if the orchards were not there.
Do they attract deer? I think they attract resident deer, but I doubt they bring deer in from long distances. They probably help to hold doe groups nearby, and that could help with attracting bucks during the rut.
Help feed the herd? I'm now dropping enough fruit and nuts that I think it is definitely helping to feed the herd. The herd would survive without the orchards, but the orchards gives more diverse food.
Present you with kill shots? Yes.
Are you frustrated at all with some of your choices? Variety? Apples, pears, persimmons, etc? Some of my early apple choices could have been better, but I'm still pretty happy. In the last few years I have fine tuned with some varieties of pears and apples that will be better choices than some of the early ones. I think a guy needs a lot of variety - apples, crabapples, pears, persimmons, chestnuts and even some early fruit like plums and cherries. The main thing in my area is to get apples and pears that are highly disease resistant.
Are they difficult to hunt from an elevated stand? Can deer get in and feed and exit without a good shot? Not difficult to hunt because of some of the planning and design that was done. Just a few of my trees are not easy to see from hunting locations, so deer can feed and exit at places without being seen. At other places my trees are at the edges of shooting lanes on a wagon wheel pattern from the hunting location. They are easy to see at those places. Of course, they can always feed at night and not be seen.
Forget about the satisfaction of growing them. Forget about human consumption. Would you do it again? Or would you focus time money and effort on a different habitat improvement? I would still do it again, because the fruit and nut trees are only a small part of my overall plan. You could put too much effort into orchards and end up being disappointed, but I don't feel like I've done that. I feel the good fall cover is my best attribute at hunting time, and the orchards are just an extra bonus.
