Implementing tree growth models as forest management tools
Abstract
In Europe there is a strong movement toward uneven-aged forest management based on the general understanding that uneven-aged mixed species stands increase or at least maintain soil fertility, increase biodiversity and improve stand resilience reducing there susceptibility to physical and/or biotic disturbances. The shift from even-aged forest management renders existing yield tables increasingly unreliable. One possibility to forecast yields for uneven-aged mixed-species stands is to develop stand growth models that operate at the individual tree level. Such individual tree growth models have been developed mainly to study stand development in uneven-aged mixed-species stands. Although tree growth models have reached a certain level of developmental maturity, there are still some theoretical areas requiring more research. However, with the majority of model development complete, the time is near for modelers to focus on identifying user related needs and testing the models ability to meet user needs. The objectives of this project are to identify missing research needs and demonstrate that individual tree growth models are a viable alternative for enhancing silvicultural decision making as well as sustainable forest resource management.
