Abstract:

The relationship between height and diameter is an essential component in forest growth and yield models and is also necessary for the estimation of the timber stocks of a forest stand. Using permanent sample plot data, eight tree height and diameter models were evaluated for their predictive abilities for pure even-aged Pinus brutia stands in Syria. The data used to build the generalized height-diameter model came from 1327 sample trees from two inventories; all sample trees in the sample plots had their diameter at breast height and height. 1115 sample trees were used for modeling, while 212 sample trees were used for validation.
Based on statistical analysis, graphical diagnostics, and biological interpretability, the model that performed best was the model proposed by Mirkovich (1958). The model can be recommended for estimating tree heights for P. brutia in Syria.
