On the Great Plains, protective devices such as tree shelters and tubex
have been very successful in insuring first year survival of seedlings. 
The protection from the cold, dry winds of winter seem to be the biggest
advantage here.  My experience in Illinois, showed a marked increase in
seedling growth when these were used.  In one case at the Mason County
state tree nursery, a red oak grew out of the top of a 48" tubex shelter
in one growing season.  The responses seem to vary with the part of the
country you are in.  Hope this helps.
