Abstract

We developed a diameter distribution model for even-aged stands of European beech in Denmark using the Weibull distribution. The model parameters were estimated using a large dataset from permanent sample plots covering a wide range of different treatments. Parameters of the model were estimated by fitting the cumulative density function using a non-linear least squares procedure. Further, a model constrained to yield estimates consistent with observed basal area was also developed. Predicted distributions confirmed the expected development of diameter distributions in even-aged beech stands. Due to large differences in initial stem-numbers care should be taken when the model is applied to young stands (<40 years). © 2006 Elsevier B.V. All rights reserved.
