Data on growth for fifty tree species during the first seven years of a reforestation experiment. Growth rates (column "GROWTH" in data) represent the difference in individual size (basal diameter measured in mm) between consecutive censuses. The column "CENSUS" represents the numeric id of each census, "ID" represents the unique ID of each individual plant, "SPECIES" represents the species name, "PLOT" represents the identity of the 30 x 30 m plot, "SUBPLOT" represents the identity of 13 x 13 m plots within each plot, "TREATMENT" represents the planting treatment (A=animal-dispersed plantings, W=wind-dispersed plantings, C=Control), "SIZE" represents the basal diameter (in mm) of each individual (at the start of each growth interval), "YEAR" represents the year of each census, and "MONTH" represents months since surveys began
