The studies are devoted to a comparative assessment of the operational characteristics of individual trees in the regions of the Northern economic area of the Russian Federation (NEA). On the basis of the estimation, the weighted average structure of the stand is obtained in terms of thickness for NEA. This made it possible to draw a conclusion about the possibility of creating a forest machine with parameters that allow it to be used effectively in all regions of the NEA.

The studies are devoted to a comparative assessment of the average performance characteristics of the timber stands of the regions of the Northern economic area (NEA). The work presents the distributions for the NEA regions: the total timber resources, the timber resources of ripe and over-mature plantations in operational forests, the volume of logging, and the volume of the cut-off area and the species composition of stand. Based on the evaluation of the performance characteristics of timber stands and individual trees, the weighted average characteristics of the model stand for NEA were calculated. The obtained results of a comparative assessment of forest resources can be used in forecasting the productivity and operating costs of forest harvesting machines operating in the conditions of NEA forests.
