Abstract

Diameter distributions in a forest stand have been successfully characterized by use of the Weibull function. Of special interest are cases where parameters of a Weibull distribution that models a future stand are predicted, either directly or indirectly, from current stand density and dominant height. This study evaluated four methods of predicting the Weibull parameters, using data from loblolly pine (Pinus taeda L.) plantations. One method, the CDF Regression, consistently produced better goodness-of-fit statistics than those from the other methods.
