Could these be used it recently logged areas,to thicken it up quicker?
Yes, but I doubt it would "thicken up quicker" than just letting an area go naturally. NWSG take two years to really get established. Two years will produce a lot of natural growth in a logged area.
Now if you wanted to favor NWSG growth over hardwood saplings in a logged area (basically, change the habitat type of the area on a long-term basis), planting NWSG in the area would certainly accomplish that, althpough broadleaf-specific herbicides would probably be needed as well.
