Using natural materials to build a barrier, it is still a man-made barrier.A natural barrier would be something like a sheer drop off like a cliff. Semantics aside, any barrier you use will work. It depends on how much work you are willing to doand if it is permissable for you to do. A couple of pros and cons..... Natural material barriers will blend in better and may be overlooked by humans. They will break down and become a non-factor for the deer.

A length of woven wire fencing will really funnel the deer and won't break down. This won't bother the deer at all, but it will catch the eye of humans and they may investigate the reason for its being.

Personally, if I could I'd use the fencing. If I was on public land I'd use natural materials.
