Abstract
One of the main characteristics of the tree is the diameter at a height of 1.3 m. This figure allows to calculate the cross-sectional area and tree planting stock. When measuring the cross-sectional area it equates to a regular geometric shape (circle or ellipse) and make the appropriate calculation formula. The highest accuracy of the ellipse corresponds to the formula, calculated on the maximum and minimum diameters. But there is a difficulty with the maximum diameter of the search. The purpose of this study - to explain which way to aim the maximum diameter of the trunk, and on what factors it depends.
