The potential productivity of forest stands is considered depending on forest conditions. Multiple regression equations are formed. As a dependent variable, the bonitet class is used. Soil, moisture and heat are the main factors affecting the development of plantings. The heat supply of locations is considered as a derivative of the topography. The moisture and fertility indicators of locations are constructed based on the characteristics of taxation stands. A significant decrease in the bonitet class as climbing is observed only in larch stands. The influence of exposure and slope on the productivity of stands is not traced. A ranked range of location moisture is demonstrated relative to a generalized qualitative indicator of forest conditions such as forest. There is a statistically significant relationship between the productivity of the stands and soil types.
