Very interesting post on the LONE PINE. I have never heard that but it makes a lot of sense. In SE Ohio we don't have any native growing pine or evergreen but it may be worth a try to plant some.

A method I have used is simply dropping "Trash Trees" in a small area to create a jungle of tree-tops, brush, etc that gets taken over into a nasty tangle once the sunlight does its work over a few months or a growing season. My tangles are filled with grapevines, multi-flora rose, sapplings & anything else that was in the forest floor as seeds or blew in. They are used a lot by deer for bedding and browse. It is very difficult to get through for us, but the deer go through it like its nothing. I also think this is good for long-term changes if wanted, the tree tops protect the saplings that end up growing up through the tangles. I've done them in small chunks, but have a friend who did this with several acres and it worked well as a sanctuary.

Good luck!
