Abstract

‘Standpak’ is a computer simulation package developed by the New Zealand Forest Research Institute and can be used to predict the quantity and quality of wood yield from a managed forest stand. The package is comprehensive and is organised in modules to facilitate the evaluation of forest stands by predicting the effects of site, stocking and silvicultural treatment on stand growth, log yield and grades, understorey grazing and cash flow. This paper presents the flow of information between the modules of ‘Standpak’ in general, and examine in detail sets of models used in the Stand Growth and Diameter Distribution modules. The benefit of, and opportunities for applying the Standpak modelling framework to predict the performance of tropical moist forests will be explored.
