There is no point in trying to document to log buyers that the trees
have been pruned.  In and of itself pruning has no bearing on the 
value of the logs.  It is the clear lumber that the tree can produce 
following pruning that potentially adds value.   In the Sierra Nevada
it would be at least 20 years before any significant amounts of clear
wood would start to accumulate.  By the time that enough clear wood
had accumulated to be of significantly increased value, the surface
features of the logs would make their increased value apparent.  That
assumes that ther is still a significant premium for clear wood 30-
40 years from now.
This is not to say that pruning can't be a paying proposition.  It 
certainly is where growth rates and clear wood premiums make it  a
very attractive investment - eg. New Zealand.  However,it is a very 
risky investment in relatively low growth rate areas, especially where
most of the mills that are likely to survive are converting to engineered
and reconstituted wood products to replace clear wood.
