I have seen ginseng doing well in places that have been select cut, 10-15 years earlier..
Clear cutting is quite different though.
If any do make it, I would expect it would be big healthy plants, with substancial root. You know it would send up a top in the spring, and for the first month or two (cooler weather), it would probably do OK, but then burn later on and die off early. It might even sit dormant for a year or two after being mis-treated like that and then after 3-4 years send up a top again.
In 3-4-5 years a clear cut area should be really over grown with brush and the ground shaded quite a bit.
I have not checked that out in a clear cut area but that seems like it might happen like that.
You know Ginseng is a survivor - and would not give up easily.
It could be that only the big old roots, in ideal growing conditions (soil wise) and on steeper north facing hillsides, or lucky ones growing on the east side of a big stump or rock - would have the chance of making it and everything else would just suffer too much and eventually die off.
