Forest Growth and Yield Modeling

Weiskittel, A. Hann, J. Kershaw and J. Vanclay,

Individual tree models ITMs are classified as growth and production models for projecting current and future forest stands. ITMs are more complex than other growth and production models, show a higher level of detail and, consequently, produce a better modeling resolution. However, the accuracy and efficiency of ITMs have not been properly assessed to date. In this study, we estimated the growth in height, diameter, and individual tree volume of a Eucalyptus urophylla plantation by applying an ITM. Each individual tree volume was estimated for future tree age.

The system can't perform the operation now. Try again later.

Global climate is changing due to increasing anthropogenic emissions of greenhouse gases. Forest managers need growth and yield models that can be used to predict future forest dynamics during the transition period of present-day forests under a changing climatic regime. In this study, we developed a forest growth and yield model that can be used to predict individual-tree growth under current and projected future climatic conditions.

Based on this, Weiskittel et al. () divided forest growth and yield models into four broad categories: (1) statistical models; (2) mechanistic; (3).
