The article analyzes calculation accuracy of growing stock by different methods when fulfilling visual taxation of forest. It is shown that the methods currently used in practice have significant systematic error leading to underestimation of growing stock. Distribution modeling of stem diameter on the basis of the average diameter ofthe stand and series of the distribution of natural diameter classes makes it possible to increase significantly the accuracy of calculation of growing stock and reduce the systematic error. More accurate methods of growing stock calculation are also more labor-intensive in terms of calculations. However, the widespread introduction of computing machinery into practice of forestry makes this disadvantage insignificant. Thus, the higher labour intensity in growing stock calculation the higher its accuracy.
