STEM RECORD METADATA
PlotNumber: Plot number
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
Phase: Code for when location occupied by stem first added to plot: 0=original plot, 1=added in first expansion, 2=second expansion, etc.
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.
Column: For some very large plots, a system of subplots were organized in columns and rows was used to facilitate data collection.  This is the column number, if applicable.
Row: For some very large plots, a system of subplots were organized in columns and rows was used to facilitate data collection.  This is the row number, if applicable.
X: X coordinate of the stem.
Y: Y coordinate of the stem.
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
stemNotes: Any notes about the particular stem, or data errors that cannot be resolved immediately.
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.
Diameter: Diameter at breast height (1.37m above ground level), in cm
heightClass: 
height: Height of the tree, in meters
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
downedAzimuth: Azimuth of downed tree trunk
yearly_remarks: Notes about the yearly measurement, including data errors that cannot be resolved immediately.
