Abstract

The study contributes to solving the problem of an uncontrolled increase in the area of derivative deciduous stands in place of indigenous coniferous forests. The aim has been to develop a method for creating an algorithm for the forest formation process, including a system of measures and allowing for a significant reduction in the likelihood of replacing indigenous dark coniferous forests with derivative deciduous stands. Based on our own scientific research and generalization of the experience of other forest scientists, a functional model of the forest formation process in dark coniferous forests has been proposed. It is presented in the form of a graphical matrix structural block diagram, based on the principles set out in the works by B.A. Ivashkevich, developed by B.P. Kolesnikov and their followers, and considers the renewal of indigenous (conditionally indigenous) forests through restoration-age shifts. The model provides 2 objective and most promising directions for the formation of dark coniferous stands: without changing coniferous species to deciduous ones and through the change of 1 generation of deciduous species. This is a matrix in whose cells the inventory characteristics of the forest stand are placed. If the actual characteristics of the inventory area coincide with those recorded in the matrix, the current state of the stand and options for the future development of the forest area are revealed. The direction of forest formation towards the formation of dark coniferous stands is achieved through thinnings and transformation fellings. The latter are a set of measures for the targeted care of young generations of coniferous species, which are carried out up to the age of felling mature birch and aspen forests. As a result, the likelihood of repopulation of areas with soft-wooded broad-leaved species and the formation of derivative soft-wooded broad-leaved stands is significantly reduced. Modern information technologies make it possible to create a digital product based on a functional model in the form of a simulation model of the forest formation process of dark coniferous stands. Its compatibility with existing forest inventory programs and practical application will allow for monitoring, forecasting, and directing forest formation processes towards the development of dark coniferous forests, effectively managing forestry production.
