Height-Diameter fixed effects models for the pine in European Russia

Abstract

The purpose of the study is to select and justify a regression model that will most accurately reflect the dependence of heights on the diameters at breast height of pine plantations in the European part of Russia. 28 height-diameter models were selected based on literary sources and tested for research. Näslund’s equation is justified as the best model for the relationship between height and diameter at chest height. It can be applied in practice when performing forestry and research work in pine forests of the European part of Russia.
