Site index model for natural stands of rebollo oak (<i>Quercus pyrenaica</i> Willd.) in Galicia, NW Iberian Peninsula.
<p>Data from stem analysis of 56 dominant trees of <em>Quercus pyrenaica</em> Willd., in natural stands in Galicia (NW Iberian Peninsula), were used to evaluate four dynamic site equations derived with the Generalized Algebraic Difference Approach (GADA). All the equations are base...

The GADA formulation derived on the basis of the Bertalanffy-Richards model by considering the asymptote and the initial pattern parameters as related to site productivity.
