Abstract
An existing growth model for biomass of forest monoculture stands is extended to simulate the growth of individual trees within the stand. The model relates growth of tree components to radiation interception, photosynthesis, respiration, assimilate partitioning, litterfall and root turnover. Competitive effects between trees are simulated in terms of shading of smaller trees by larger. The model reproduces some known behaviour of forest stands. It has considerable flexibility in its ability to deal with the effects on growth of a wide range of environmental circumstances.
