Models of potential height and diameter for Eucalyptus globulus in Portugal

Document Type


Publication Date



When modeling tree dimensions, it is common in many forest growth models to first predict the potential diameter or height in the absence of resource limitation, and then to modify this downward using functions reflecting the impact of various limiting resources on growth. Most of these models, however, were not parameterized using observations of true potential growth. This study utilizes data from a field trial of Eucalyptus globulus in central Portugal to parameterize models of potential height and diameter of E. globulus in the absence of growth reduction due to moisture or nutrient limitation. The resulting models represent tree height and diameter as functions of a single variable, the growing degree days (5°C basis) accumulated since the date of planting. © 2002 Elsevier Science B.V.
