Estimating Dbh from Stump Diameter for 15 Southern Species

Data used in this study were gathered In Louisiana (1973) as part of a wood utilization study. The number of samples ranged from 436 for loblolly pine to 14 for yellow-poplar. A species test subset was extracted from every species data set which contained more than 30 sample trees. The majority of the trees were sawtimber size with mean dbh of 12.7 inches for softwoods and 14.4 inches for hardwoods. The mean stump height was 0.8 feet for softwoods and 1.0 feet for hardwoods (table 1).
