I agree about raising the minimum root age to dig up to 10 years. I know in my area, there are plenty of 10+ year roots that I get partially dug out, and see how small the root is, and just put it back. No point digging a 10, 15, 20 year old root that is only the size of a peanut shell.
I like the idea of dealers only buying fresh dug roots also, there is certainly no way roots dug in June could be legally bought in Sept.
My sister has taken an interest in ginseng lately, not for digging, but for preservation. I know she has been in contact with other professors at Penn State, and also with the GC, PA Dept of Natural Resources, and Forestry Service.
She said that most believe that ginseng will be classified as an endangered species in PA within 10 years.
