Functional–structural tree models can be used not only for biomass and crown architecture modelling, but also for wood properties. Using L-system language, Fernández et al. develop a model based on plant allometry and environmental signals so that a harmonic growth can be achieved, and by using monthly steps detailed three-dimensional information for crown and wood characteristics is obtained. The model is parameterized for Pinus radiata and validated against forestry inventory data with encouraging results, with the cyclical pattern and increase in growth rings being reasonably well modelled.
