I was much deeper in the woods on my property today, scouting for more good sites to plant germinated seed. I happened upon several dozen small patches of younger plants. Nothing found that was as old as those that were poached last year, but there were plenty of them. Lots of single prong with 5 leaflets, fewer 2 prongs and just a few 3 prongs. It was raining lightly so I did not bring my phone to get pics. I did not see any 3 leaflet seedlings near them so I'm guessing that these were from seeds spread a few years ago by critters that dropped them after grazing the older plants. They were much further up the holler from where the older plants were poached, and growing in clusters of plants in close proximity to one another. They were on both the eastern and western slopes of the north facing holler with predominantly maple and poplar.
