Abstract Taxation standards, including growth tables, play an important role in the design of forestry activities and the organization of management in forest areas, but it still cannot be argued that they fully reflect all the features of the dynamics of forest stands in various forest growing conditions. The present work is devoted to filling in the gaps in the characteristics of the growth features of Siberian fir (Abies sibirica L.) stands within the West Siberian southern taiga plain forest region. The aim of the work was to develop models of growth and development of the most common types of forests of the fir formation within the boundaries of the study area. The work is based on the materials of the mass inventory of 3491 stands, while 1367 stands belonged to the stands of the forb group of forest types, and 2124 stands to the green moss. Modeling was carried out for average height (H), average diameter (D), stock (M) of stands. As a result of the study, mathematical models of the dynamics of the taxation indicators of Siberian fir stands of two most common groups of forest types in the study area - green moss fir forests and forb fir forests - were constructed. For practical use, tables of the course of growth of modal fir stands were developed, which were supplemented with information on the age dynamics of phytomass and carbon concentration.
