All measurements are in metric units.
Fourteen 20x20m plots were established in 1984. Tree data from all 14 plots are combined by year of measurement, so there is a separate file with the same structure for each year trees were measured. For each plot, diameter measurements are listed by species, but not by individual tree. Thus, the rows in the data spreadsheet are variable in length, depending on how many trees of each species were found in each plot. Diameters for each tree in the plot are listed by species.
