Chumachenko S.I., Smirnova O.V. Modeling of Succession Dynamics of Forest Stands
// Forest Science (Lesovedenie). 2009. No 6. P. 3-17 (in Russian). The results of modeling the succession dynamics of forest stands using the FORRUS-S model are presented. An algorithm for the calculation of the succession stand status was elaborated. This algorithm is based on the determination of the age and ontogenetic status, tree species strategy types, the age structure of stands, and the presence or absence of dead wood at different stages of decomposition. A scheme of succession development of stands from different initial stations (after fire, tillage, and cuttings) was elaborated. The results on modeling of spontaneous (natural, undisturbed) development of stands after clear cutting are presented. Simulation of succession dynamics was carried out for southern taiga forest stands at the Chukhlomskii leskhoz (Kostroma region). The model experiment showed that the restoration of the natural composition and structure of mixed coniferous-broad-leaved forests appeared to occur for the life time of three-four generations of late succession species. The algorithm proposed can be used for assessing the succession status of forest stands from different natural zones in the availability of required specific biological and ecological information.
