The state inventory of forests (SIF) in the Russian Federation is a set of measures to assess the condition of forests, their quantitative and qualitative characteristics and is a strategically important type of forest accounting. However, the system of inventory works borrowed from the countries of Western Europe could not be fully adapted to the Russian conditions. The procedure for conducting the GIL does not contribute to the dynamic implementation of the project, and the methodology for conducting the SIF needs to be adjusted. The aim of the work is to optimize the activity on the state forest inventory when laying test plots. The materials of forest inventory, SFR data, the work of leading scientists on similar topics have been analyzed. When determining the factors that have the greatest significance for the variation of the stand stock, a statistical method based on correlation-regression analysis was applied. The most significant were the planting age, trunk diameter, and type of forest growing conditions (FGC). It is proposed to use the type of forest growing conditions as a unified unit of stratification. This indicator can be used equally on wooded and unforested land. It has been established that the territories where it is advisable to conduct SIF with a predominance of remote sensing methods are about 70%. A simplified method for laying test plots at SIF is proposed, which will enable to lay of a larger number of test plots per unit of time without losing the quality of inventory work
