S10 Sapling Mapping data notes

The original instructions for this study specified recording condition as 
only COND 0 or 1 rather than the 0-6 used elsewhere.  Over the years
conditions proliferated and values for S10 COND now run 0-9, as follows
(the great majority being still 0 or 1):
0: alive
1: dead
2: cull
3: dead top
4: almost dead
5: dead, still standing
6: dead and down
7: outgrowth
8: beaver (quadrat 3E1 only)
9: TSI	(harvest blocks only)


STATION indicates the flag from which each sapling was sighted and recorded 
but sightlines and terrain make it impossible to take observations from each 
flag systematically.  Therefore STATION is not a reliable description of 
sapling location; rather, it should be considered part of each sapling's 
identifier.
