I'm surprised at how many plants are there even tho I sowed it 20 years ago but I'm kinda more surprised that there's not bigger stuff in it. I have around 30 4 prongs, hundreds of 3 prongs and hard to say how many 2s and 3 leafers.
Welcome to the Board. Things are kind of screwed up at the moment. People having problems posting pictures and such. I see bitternut hickory and a boatload of enchanter's nightshade. Habitat I have seen in the Valley. Stick around.
I would not do any thinning of herbaceous plants. That stuff provides cover and concealment. I have already experimented with thinning of hardwood trees. The results were a disaster.
Just don't plant ginseng where wood nettle grows. Also avoid large populations of blue cohosh. Everything else seems harmless.
