but back to feeding....it has no effect if you do all winter stop half way or don't at all deer will seek out the best habitat..
Sorry but you are wrong on this. In an area that where winters are severe enough that winter mortality can occur, you most certainly WILL create an effect on the native habitat. That's the most important thing...native habitat...that most people with the best of intentions completely overlook. This isn't about the deer. It's about the native ecosystem that they inhabit. Artifically high deer numbers in an area who's native WINTER carrying capacity is less than what's there can damage that ecosystem to the extreme, and maybe permanently.
Mother Nature can be a real b****. The result of keeping deer numbers higher than what the native winter habitat can support are deer die offs (at the best case scenario...deer can recover VERY quickly their population numbers), and LONG TERM HABITAT DESTRUCTION (at the worst) which can DECADES to rejuvanate...if ever. This not only further reduces deer numbers, but also all the other wildlife in the area.
If you can't identify the specific ecosystem you're in, or the plant species in it, OR the current state of plant succession, then all you are doing by supplementally feeding is throwing darts in a dark room. You have NO idea of what's there, what you've hit, what you've damaged, or how severe the damage may be.
Get a professional to assist you in making a plant inventory, and then come up with a management plan that can maybe increase the winter carrying capacity and be happy with that. If all you want are lots of deer, and then just fence the land and make a feedlot out of it, then you can see all kinds of deer. Who knows? You may even get a real live, honest to goodness TV hunting show personality to come and film an episode on it! [;)]
