what seems to be missed here maybe for some vague ideas of it being less "natural" is that every hedgerow that I've ever seen that is being used as a livestock barrier has a hefty dose of barbed wire preventing the livestock from going through. You can nail barbed wire right into trees and bushes and attach electric fences with screw on attachments right into trees. Works great. Still has all the benefits for nature but is much more practical from a farmer point of view.
