Abstract:
Integrating the multi-functional role of forests in forestry practices constitutes a challenging example of complex system management. Usually, win-win situations between functions are seldom and trade-offs have to be considered. This paper proposes a framework to study dynamical relationships between two important functions in forests: timber production and biodiversity conservation. We built an individual-based model of uneven-aged forests that explicitly takes into account timber harvesting options and dead wood dynamics. Dead wood compartment was selected because it represents a relevant surrogate for biodiversity in forests. We used dynamics metrics based on viability theory framework to evaluate simulations that contrasted different thinning intensities and thinning frequencies. Thanks to this model and the metrics used, we are able to discuss optimal strategies for preserving biodiversity while guaranteeing timber production.
