The paper considers the issue of using the stem taper to model the form factor of pine tree trunks in the Kostroma region. It has been determined that the diameter values predicted by the model can be used to establish the taxation characteristics of trunks. Based on the results of field work and archival data, 10064 diameter measurements were obtained at various heights for 689 pine trees growing in the Kostroma region. The quality of the application of the stem taper model for calculating the form factor was assessed using quality metrics generally accepted in statistics based on data from the analysis of tree trunks. It has been established that the use of the considered stem taper model for calculating the main taxation indicators of tree trunks in pine forests of the Kostroma region will help to increase the accuracy of determining the stock of forest range and will be important for scientific research.
