Well, they do a number on grain fields like oats but I do nor know about the timing with regards to hunting seasons. The other option would be to plant berries of some kind. Again the problem of berries would be to find ones that would ripen during the hunting season.
Blackberry and Rasberry would do good at that time of year. I would think that the vines are fast growing too, giving you a sizable cache in the first year. I think it's a neat idea! Keep us posted with the results.
Your season opens just before ours here in the Upper Peninsula and that is about when oats rippen. I had a friend who had an oat field next to his house watch a 400# bear go out into a unharvest oat field, lie down and just reach out and sweep the stalks into his mouth and strip off the grain heads. He wanted his son to shoot that bear but from ground level he could not see the bear because of the stalk height and from the deck, it was around a 400 yd shot that he did not feel confident in trying. The bear filled up on oats and wandered back into the woods.
We have a lot of late ripening apple trees around my place and the bears love 'em. I know it take more than 7 years to get a good tree to bare good fruit so I would look around and see if you already have some growing. When I'm scouting bears I always look for claw marks on the trunks of apple trees. The bears mark their territory and then come back for more later.
I learned this the hard way last year. If you're hunting in an area with lots of bear activity, it's a great idea to stash your food and water up in a tree. I like to wrap everything in a tarp and tie it between two trees. Don't just tie it up in one tree but tie it in between two trees at least 15 feet in the air. I thought I had my backpacking camp's food supply stashed pretty well last year. I returned to camp during the first weekend of archery to find all my food destroyed. Make sure...
