most of that area has naturally poor sandy soils and has naturally burned for 
centuries on top of that, it had stunted growth at the time of the first new 
European settlers arrival

in some areas down there no trees grows above 4-5' or so and even in an average 
area they are always stunted to some extent over large portions of the region

it's one of the very few totally natural stunted pitch pine areas, it's nothing 
at all like Marion Brooks

Barry,

Do you think the smaller stunted trees are similar in age to the larger ones 
nearby?  Sometimes stunting is because of high acidity or some exotic mineral 
formed from the weathering of the bedrock. There should not be that drastic of 
a difference geologically in this location to cause the stunting.  In this 
location, I do not think they are stunted because of lack of water.  From the 
setting it looks as if they would not need to develop very long roots to reach 
water - so that is not a likely explanation.

The best suggestion I can make is that this particular area had been subject to 
a severe fire, maybe from a big brush pile after logging or just brush itself 
that grew after logging.  If the fire is severe enough it will destroy the 
organic components of the soil and the soil structure leaving behind a mineral 
soil that will not support many plant species.  These are first occupied by 
some pioneering species, but it will take decades to a couple hundred years 
before the soil rebuilds enough to support "normal" vegetation.  This is what 
happened at Marion Brooks Natural Area in central Pennsylvania.  After eighty 
or ninety years there are still large section that only are growing  
blueberries and bracken fern.  What trees that are present in the worst hit 
areas are paper birch and to a lesser extent pitch pine.  

In your area of the pine barrens the succession is likely first some of the 
lichens and hedges, then perhaps the pitch pines.  But just because they will 
sprout there does not mean they will grow well.  The trees in these areas are 
typically stunted by the poor nutrients and nature of the soil.  I think that 
is what is happening here.  These trees are stunted because they are growing in 
an area particularly hard hit by fires that ruined the soil structure.
