Thanks for these additional comments.
Alan – The problem with erecting fences in the woods is that they require constant maintenance to clear fallen trees, grapevines, etc. So people might well think twice before putting them up. Roger Latham Sr. put up numerous deer exclosures in northern PA back in the 50s, when he was a biologist for the Game Commission, but only one survived – the famous Latham Fence.
patry – Those aren’t leaves, but witch hazel blossoms. They start blooming in late October and usually keep going through the second or third week of November here, lighting up the woods.
