Abstract

Data for Pinus radiata D. Don grown in the Australian Capital Territory (ACT) are used to show that annual indices of growth potential can be successfully incorporated into Schumacher projection models of stand basal area growth. Significant reductions in the error mean squares of the models can be obtained by including an annual growth index derived from estimates of photosynthesis simulated with a detailed process-based model: BIOMASS. In the ACT, it was sufficient to estimate the growth index at a single location within the forest estate.
