Bear Hunting on your land WILL decrease your deer hunting opportunities for archery hunting. I used to bear hunt a lot more when I got a license every year. A good bear bait will create a zone where the deer will vacate. For me it seemed to be about a 25 plus acre piece would be devoid of deer. Once I quit baiting and the bears left, the deer would come back, but it still took several weeks to do so. By Mid October at the latest, everything was back to normal.
