Based on the stand-wise database of IA “Ukrderzhlisproekt” as of January 1, 2011, main mensurational indices, namely mean height, mean diameter and growing stock per hectare of common oak stands in Ukrainian Polissia, have been modelled. Mathematical models employ allometric (power) function (for mean diameter modeling) and Mitscherlich growth function (for mean height and growing stock modeling). Using the data collected at temporary sample plots, where model trees were cut down and measured, mean form factor of common oak stands in Ukrainian Polissia has been modeled. The developed mathematical models together with conventional forest mensuration formulas have enabled development of yield tables for modal stands of common oak of natural (seed) origin in Ukrainian Polissia. The resulting yield tables describe tree stands and their removed parts (due to natural thinning or forest management activities). For removed part, reduction numbers and form factors that were obtained for common oak stands in ForestSteppe zone of Ukraine are used, since intensity of management activities in these natural zones does not differ significantly.
