COLUMN KEY FOR LILLEY CORNETT WOODS OVERSTORY DATA
Header: Description
Year: Year data was collected
Plot Name: Plot name indicating topographic position based on aspect (N = North, E = East, S = South) and elevation (U = Upper, M = Mid, L = Lower)
Plot No: Numerical plot ID; ranges from 1 to 80
Species: Scientific species name
dbh: diameter at breast height; measured in centimeters (cm)
status: dead (D) or alive (L)

NOTE: The 1999 data is missing plot 73 (SL03) because the plot stake could not be located that year.
