Modelling the growth tables of the oak stands of seed origin of the Voronezh region by type of forest growing conditions

Abstract

Growth rate tables (GRT) used by the forest industry, as a rule, are built according to yield class and have a utilitarian focus. Based on forest inventory data, we built multidimensional models and GRTs for oak (Querqus robur L.) stands for 10 types of forest growing conditions, reflecting the dynamics of forest inventory indicators depending on the age and basal area of stands, and the abundance of oak in the overall species composition. The obtained GRTs in the age range of 10-300 years, for the basal area in the range of 0.3-1.0 and the share of oak in the overall species composition of 1-10 units, can be used in surveys of oak stands based on the measurements of the average heights, diameters and sums of cross-sectional areas.
