Taxation characteristics of the features of the forest fund of the Barnaul forestry of the Altai territory

The study was conducted in order to identify forestry and taxation features of forest plantations in the Barnaul forestry of the Altai Territory, located in the suburban area of Barnaul. Areas of the forest fund were selected at different distances from the city of Barnaul: in the zone of a dense network of roads and settlements (0-15 km) and in the zone of less intensive infrastructure (37 km). Using the methods of ecological profiles, variation statistics, comparative analysis, and forest taxation, the taxation materials of 32 forest quarters were processed, including data from 718 forest taxation allotments. Using two-factor analysis of variance, it was found that the individual studied indicators of forest plantations (average height, completeness, bonus class and reserve per 1 ha) depend on the type of forest. The taxation indicators of stands in the suburban area (except for the average stock per 1 ha) do not have a reliable dependence on the features of Barnaul. The analysis of variance in relation to the natural renewal of the main breed showed that the average height and density depend on the type of forest, and the distance from the city limits affects only the average density. High values of occurrence (65.4-89.5%) of undergrowth were noted in fresh forest, lower in grass forest (15.5-48.4%), but the occurrence increases with distance from the city in both types of forest. Ash-leaved maple finds its ecological niche mainly in the grass forest, displacing local plant species, preventing the natural renewal of pine. It has been previously established that the parameters of forest plantations in suburban pine forests of Barnaul depend on the type of forest, showing different structural and positional stability in relation to anthropogenic factors.
