STEM RECORD METADATA
plotNumber: Plot number
Transect: Transect on which the stem was observed.  PSP and mapped tree plots have transects that are contiguous, seedling and sapling plots have discontiguous transects.
plotStemID: Stem ID that is unique only within the plot
ClonePlotStemID: Unique PlotStemID of parent stem of a clone (usually the first measured) This does NOT reference globalStemID
SpeciesCode: 4-letter species code for the species of the stem.  These code are translated into scientific names in another export.
ScientificName: Full scientific name of the species
X: X coordinate of the stem.
Y: Y coordinate of the stem.
Year: Year the stem was observed in yearly data.
conditionCode: 1 = alive and reasonably intact, 2 = dead (confirmed as such by the presence of a dead stem), 3 = missing (presumed dead, but no stem could be found for verification), 4  die back to below breast height (a marginal note was usually made indicating the possible cause of damage), 5  cut (sawed down by humans), 6  Damage from Hurricane (see special hurricane fields), Missing value = not a tree or not observed.
SeedlingCrownClass: 
BasalDiameter: Diameter at stem base, in mm
SeedlingHeight: Seedling height, in mm, up to 2000 (=2m).  -1 indicates taller than 2000mm
LeafCount: The number of leaves on the seedling, up to 20.  99 indicates more than 20.  Pine leaves were not counted, but were always listed as 99.
SeedlingAge: Estimated age of the seedling when first added to the dataset, estimated from the number of internodes observed.
hurricane1_uproot: Uprooting status (1 = OK, 2 = partial uproot, 3 = complete uproot)
hurricane2_breakage: Breakage (1 = less than 10% canopy loss, 2 = 10-35% canopy loss, 3 = 35-90% canopy loss, 4 = more than 90% canopy loss)
hurricane3_leaning: Leaning (1 = OK, 2 = leaning free, with lean over 10%, 3 = supported by another tree, 4 = down (on ground)
hurricane4_leanedon: Leaned on (1 = free, 2 = upright, supporting a tree ( DBH >30% size of host), 3 = bent or leaning (crown displaced at least 10%), 4 = pinned
