Title:
Modeling forest canopy dynamics to introduce seasonality in phenomenological growth & yield models

Abstract: This talk presents several elements of my PhD thesis.
First, I will give an overview (non-exhaustive) of modelling issues related to phenomenological growth & yield models. They are widely used to optimize sylvicultural practices at forest stand level. Nevertheless, the parameters of such models are strongly site-dependent and do not consider explicitly the environmental (soil composition and climate) influence. This reduces strongly their general use. Second, I will present a strategy aiming to overcome the limitations. In particular, I will describe the SLCD model (stand leaf canopy dynamics) created for the occasion.
Finally, I will consider the application of SLCD to a tropical evergreen forest ecosystem (eucalyptus, Brazil). It consists in: i) introducing a specific formalism of SLCD components dedicated to these particular ecosystems; and ii) parameters estimation using multi-objective optimization.
