Around our place, all you need is barbed wire and time. Volunteer cedars and hawthorn trees do the rest. That's at Deer Camp. Up in Cincinnati, a fence line gets choked pretty quickly with locust, mulit-flora rose and honeysuckle.
My advice is this:
[ul][*]Go driving and see what is choking the neighboring fence lines, and then find the stuff on your property and transplant it along a 4-strand barbed wire fence.
[*]Get a visit from the state wildlife biologist and ask for help. He will give you a bunch of help to reach your wildlife management goals.
If you're there all the time, you can easily transplant trees and bushes to this new hedgerow. The problem that I found is that unless you're there to water everything during the dry spells, you're screwed. I learned that the hard way.
Now, I transplant only the smallest of the hardiest plants, I do it in late Fall. I don't expect much, and I have a few rewards. Mostly it's just volunteer stuff that fills in. I also plant a lot of seeds and acorns. I have a few stretches of fence I'm trying to do this way. In 5 years, I've coaxed a few cedars and a few small maple saplings, and a hawthorn or two. The next wet summer we get, I'm sure things will start to take off. It's a snowball thing. Once the seedlings get above the grass and start providing shade, it inhibits evaporation and grass growth which promote more trees and bushes, etc.
If you're trying to influence deer movement, the barbed wire won't do a whole lot, but it's a start. Piling brush along the fence will aid it. The trick is to make it harder in one spot for them to cross and easier in another spot close by. I have one spot that the deer were crossing that was too far away for a bow shot. I put in another hole closer to the stand and did everything I could to stop their passage at the old one. Finally, 5 strands of wire and a bunch of limbs later, they decided to go to the new spot. A tree fell across a fence during Hurricane Ike, and now I have the same problem at another stand.
