Individual-based model of spatio-temporal dynamics of mixed forest stands

•Individual-based model of spatiotemporal dynamics of mixed forest stands.•Eco-physiological model of tree growth under competition for light.•Simulation of the natural single- and mixed-species stands dynamics.•Simulation of the effects of different types of disturbances on the stand dynamics and compositions.

This research presents the results of constructing and parameterizing an individual-based model of spatiotemporal dynamics of mixed forest stands. The model facilitates computerized experiments with forest stands having different combinations of species and age structures. These forest stands grow on temperate areas where light is the main system-forming factor that shapes and develops forest ecosystems. The model TEMFORM (TEMperate FORests Model) is developed with few equations and parameters, most of which can be estimated using standard forest inventory data. Parameterization of the model used the growth tables of a set of basic forest-forming species in Far East Russia. Simulation results of the development of the natural single- and mixed-species stands and the effects of different types of disturbances on the stand dynamics and compositions are presented.
