Abstract:

Equations for predicting total aboveground dry weights from height (H) and/or basal diameter (D) were developed from leafless, open-grown seedlings and saplings. Separate linear regressions were fitted to predict biomass for Quercus alba L., Q. velutina Lam., Acer rubrum L., A. saccharum Marsh., Nyssa sylvatica Marsh., Prunus serotina Ehrh., Fraxinus americana L., Sassafras albidum (Nutt) Nees, Liriodendron tulipifera L., and Populus grandidentata Michx. The general model used was Log10Y = b0 + b1 Log10X, where Y denotes aboveground ovendry (700°C) weight of the plant, and X is either D²H or D² alone. In nearly all cases, equations for species having similar ovendry specific gravities were not significantly different and could be combined. Forest Sci. 30:523-527.
